What Is a Case Study? | Definition, Examples & Methods

Published on May 8, 2019 by Shona McCombes . Revised on November 20, 2023.

A case study is a detailed study of a specific subject, such as a person, group, place, event, organization, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research.

A case study research design usually involves qualitative methods , but quantitative methods are sometimes also used. Case studies are good for describing , comparing, evaluating and understanding different aspects of a research problem .

Table of contents

When to do a case study, step 1: select a case, step 2: build a theoretical framework, step 3: collect your data, step 4: describe and analyze the case, other interesting articles.

A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case.

Case studies are often a good choice in a thesis or dissertation . They keep your project focused and manageable when you don’t have the time or resources to do large-scale research.

You might use just one complex case study where you explore a single subject in depth, or conduct multiple case studies to compare and illuminate different aspects of your research problem.

Once you have developed your problem statement and research questions , you should be ready to choose the specific case that you want to focus on. A good case study should have the potential to:

• Provide new or unexpected insights into the subject
• Challenge or complicate existing assumptions and theories
• Propose practical courses of action to resolve a problem
• Open up new directions for future research

TipIf your research is more practical in nature and aims to simultaneously investigate an issue as you solve it, consider conducting action research instead.

Unlike quantitative or experimental research , a strong case study does not require a random or representative sample. In fact, case studies often deliberately focus on unusual, neglected, or outlying cases which may shed new light on the research problem.

Example of an outlying case studyIn the 1960s the town of Roseto, Pennsylvania was discovered to have extremely low rates of heart disease compared to the US average. It became an important case study for understanding previously neglected causes of heart disease.

However, you can also choose a more common or representative case to exemplify a particular category, experience or phenomenon.

Example of a representative case studyIn the 1920s, two sociologists used Muncie, Indiana as a case study of a typical American city that supposedly exemplified the changing culture of the US at the time.

While case studies focus more on concrete details than general theories, they should usually have some connection with theory in the field. This way the case study is not just an isolated description, but is integrated into existing knowledge about the topic. It might aim to:

• Exemplify a theory by showing how it explains the case under investigation
• Expand on a theory by uncovering new concepts and ideas that need to be incorporated
• Challenge a theory by exploring an outlier case that doesn’t fit with established assumptions

To ensure that your analysis of the case has a solid academic grounding, you should conduct a literature review of sources related to the topic and develop a theoretical framework . This means identifying key concepts and theories to guide your analysis and interpretation.

There are many different research methods you can use to collect data on your subject. Case studies tend to focus on qualitative data using methods such as interviews , observations , and analysis of primary and secondary sources (e.g., newspaper articles, photographs, official records). Sometimes a case study will also collect quantitative data.

Example of a mixed methods case studyFor a case study of a wind farm development in a rural area, you could collect quantitative data on employment rates and business revenue, collect qualitative data on local people’s perceptions and experiences, and analyze local and national media coverage of the development.

The aim is to gain as thorough an understanding as possible of the case and its context.

In writing up the case study, you need to bring together all the relevant aspects to give as complete a picture as possible of the subject.

How you report your findings depends on the type of research you are doing. Some case studies are structured like a standard scientific paper or thesis , with separate sections or chapters for the methods , results and discussion .

Others are written in a more narrative style, aiming to explore the case from various angles and analyze its meanings and implications (for example, by using textual analysis or discourse analysis ).

In all cases, though, make sure to give contextual details about the case, connect it back to the literature and theory, and discuss how it fits into wider patterns or debates.

Case studies

Case studies are essential to qualitative research , offering a lens through which researchers can investigate complex phenomena within their real-life contexts. This chapter explores the concept, purpose, applications, examples, and types of case studies and provides guidance on how to conduct case study research effectively.

Whereas quantitative methods look at phenomena at scale, case study research looks at a concept or phenomenon in considerable detail. While analyzing a single case can help understand one perspective regarding the object of research inquiry, analyzing multiple cases can help obtain a more holistic sense of the topic or issue. Let's provide a basic definition of a case study, then explore its characteristics and role in the qualitative research process.

Definition of a case study

A case study in qualitative research is a strategy of inquiry that involves an in-depth investigation of a phenomenon within its real-world context. It provides researchers with the opportunity to acquire an in-depth understanding of intricate details that might not be as apparent or accessible through other methods of research. The specific case or cases being studied can be a single person, group, or organization – demarcating what constitutes a relevant case worth studying depends on the researcher and their research question .

Among qualitative research methods , a case study relies on multiple sources of evidence, such as documents, artifacts, interviews , or observations , to present a complete and nuanced understanding of the phenomenon under investigation. The objective is to illuminate the readers' understanding of the phenomenon beyond its abstract statistical or theoretical explanations.

Characteristics of case studies

Case studies typically possess a number of distinct characteristics that set them apart from other research methods. These characteristics include a focus on holistic description and explanation, flexibility in the design and data collection methods, reliance on multiple sources of evidence, and emphasis on the context in which the phenomenon occurs.

Furthermore, case studies can often involve a longitudinal examination of the case, meaning they study the case over a period of time. These characteristics allow case studies to yield comprehensive, in-depth, and richly contextualized insights about the phenomenon of interest.

The role of case studies in research

Case studies hold a unique position in the broader landscape of research methods aimed at theory development. They are instrumental when the primary research interest is to gain an intensive, detailed understanding of a phenomenon in its real-life context.

In addition, case studies can serve different purposes within research - they can be used for exploratory, descriptive, or explanatory purposes, depending on the research question and objectives. This flexibility and depth make case studies a valuable tool in the toolkit of qualitative researchers.

Remember, a well-conducted case study can offer a rich, insightful contribution to both academic and practical knowledge through theory development or theory verification, thus enhancing our understanding of complex phenomena in their real-world contexts.

What is the purpose of a case study?

Case study research aims for a more comprehensive understanding of phenomena, requiring various research methods to gather information for qualitative analysis . Ultimately, a case study can allow the researcher to gain insight into a particular object of inquiry and develop a theoretical framework relevant to the research inquiry.

Why use case studies in qualitative research?

Using case studies as a research strategy depends mainly on the nature of the research question and the researcher's access to the data.

Conducting case study research provides a level of detail and contextual richness that other research methods might not offer. They are beneficial when there's a need to understand complex social phenomena within their natural contexts.

The explanatory, exploratory, and descriptive roles of case studies

Case studies can take on various roles depending on the research objectives. They can be exploratory when the research aims to discover new phenomena or define new research questions; they are descriptive when the objective is to depict a phenomenon within its context in a detailed manner; and they can be explanatory if the goal is to understand specific relationships within the studied context. Thus, the versatility of case studies allows researchers to approach their topic from different angles, offering multiple ways to uncover and interpret the data .

The impact of case studies on knowledge development

Case studies play a significant role in knowledge development across various disciplines. Analysis of cases provides an avenue for researchers to explore phenomena within their context based on the collected data.

This can result in the production of rich, practical insights that can be instrumental in both theory-building and practice. Case studies allow researchers to delve into the intricacies and complexities of real-life situations, uncovering insights that might otherwise remain hidden.

Types of case studies

In qualitative research , a case study is not a one-size-fits-all approach. Depending on the nature of the research question and the specific objectives of the study, researchers might choose to use different types of case studies. These types differ in their focus, methodology, and the level of detail they provide about the phenomenon under investigation.

Understanding these types is crucial for selecting the most appropriate approach for your research project and effectively achieving your research goals. Let's briefly look at the main types of case studies.

Exploratory case studies

Exploratory case studies are typically conducted to develop a theory or framework around an understudied phenomenon. They can also serve as a precursor to a larger-scale research project. Exploratory case studies are useful when a researcher wants to identify the key issues or questions which can spur more extensive study or be used to develop propositions for further research. These case studies are characterized by flexibility, allowing researchers to explore various aspects of a phenomenon as they emerge, which can also form the foundation for subsequent studies.

Descriptive case studies

Descriptive case studies aim to provide a complete and accurate representation of a phenomenon or event within its context. These case studies are often based on an established theoretical framework, which guides how data is collected and analyzed. The researcher is concerned with describing the phenomenon in detail, as it occurs naturally, without trying to influence or manipulate it.

Explanatory case studies

Explanatory case studies are focused on explanation - they seek to clarify how or why certain phenomena occur. Often used in complex, real-life situations, they can be particularly valuable in clarifying causal relationships among concepts and understanding the interplay between different factors within a specific context.

Intrinsic, instrumental, and collective case studies

These three categories of case studies focus on the nature and purpose of the study. An intrinsic case study is conducted when a researcher has an inherent interest in the case itself. Instrumental case studies are employed when the case is used to provide insight into a particular issue or phenomenon. A collective case study, on the other hand, involves studying multiple cases simultaneously to investigate some general phenomena.

Each type of case study serves a different purpose and has its own strengths and challenges. The selection of the type should be guided by the research question and objectives, as well as the context and constraints of the research.

The flexibility, depth, and contextual richness offered by case studies make this approach an excellent research method for various fields of study. They enable researchers to investigate real-world phenomena within their specific contexts, capturing nuances that other research methods might miss. Across numerous fields, case studies provide valuable insights into complex issues.

Critical information systems research

Case studies provide a detailed understanding of the role and impact of information systems in different contexts. They offer a platform to explore how information systems are designed, implemented, and used and how they interact with various social, economic, and political factors. Case studies in this field often focus on examining the intricate relationship between technology, organizational processes, and user behavior, helping to uncover insights that can inform better system design and implementation.

Health research

Health research is another field where case studies are highly valuable. They offer a way to explore patient experiences, healthcare delivery processes, and the impact of various interventions in a real-world context.

Case studies can provide a deep understanding of a patient's journey, giving insights into the intricacies of disease progression, treatment effects, and the psychosocial aspects of health and illness.

Asthma research studies

Specifically within medical research, studies on asthma often employ case studies to explore the individual and environmental factors that influence asthma development, management, and outcomes. A case study can provide rich, detailed data about individual patients' experiences, from the triggers and symptoms they experience to the effectiveness of various management strategies. This can be crucial for developing patient-centered asthma care approaches.

Other fields

Apart from the fields mentioned, case studies are also extensively used in business and management research, education research, and political sciences, among many others. They provide an opportunity to delve into the intricacies of real-world situations, allowing for a comprehensive understanding of various phenomena.

Case studies, with their depth and contextual focus, offer unique insights across these varied fields. They allow researchers to illuminate the complexities of real-life situations, contributing to both theory and practice.

Understanding the key elements of case study design is crucial for conducting rigorous and impactful case study research. A well-structured design guides the researcher through the process, ensuring that the study is methodologically sound and its findings are reliable and valid. The main elements of case study design include the research question , propositions, units of analysis, and the logic linking the data to the propositions.

The research question is the foundation of any research study. A good research question guides the direction of the study and informs the selection of the case, the methods of collecting data, and the analysis techniques. A well-formulated research question in case study research is typically clear, focused, and complex enough to merit further detailed examination of the relevant case(s).

Propositions

Propositions, though not necessary in every case study, provide a direction by stating what we might expect to find in the data collected. They guide how data is collected and analyzed by helping researchers focus on specific aspects of the case. They are particularly important in explanatory case studies, which seek to understand the relationships among concepts within the studied phenomenon.

Units of analysis

The unit of analysis refers to the case, or the main entity or entities that are being analyzed in the study. In case study research, the unit of analysis can be an individual, a group, an organization, a decision, an event, or even a time period. It's crucial to clearly define the unit of analysis, as it shapes the qualitative data analysis process by allowing the researcher to analyze a particular case and synthesize analysis across multiple case studies to draw conclusions.

Argumentation

This refers to the inferential model that allows researchers to draw conclusions from the data. The researcher needs to ensure that there is a clear link between the data, the propositions (if any), and the conclusions drawn. This argumentation is what enables the researcher to make valid and credible inferences about the phenomenon under study.

Understanding and carefully considering these elements in the design phase of a case study can significantly enhance the quality of the research. It can help ensure that the study is methodologically sound and its findings contribute meaningful insights about the case.

Conducting a case study involves several steps, from defining the research question and selecting the case to collecting and analyzing data . This section outlines these key stages, providing a practical guide on how to conduct case study research.

Defining the research question

The first step in case study research is defining a clear, focused research question. This question should guide the entire research process, from case selection to analysis. It's crucial to ensure that the research question is suitable for a case study approach. Typically, such questions are exploratory or descriptive in nature and focus on understanding a phenomenon within its real-life context.

Selecting and defining the case

The selection of the case should be based on the research question and the objectives of the study. It involves choosing a unique example or a set of examples that provide rich, in-depth data about the phenomenon under investigation. After selecting the case, it's crucial to define it clearly, setting the boundaries of the case, including the time period and the specific context.

Previous research can help guide the case study design. When considering a case study, an example of a case could be taken from previous case study research and used to define cases in a new research inquiry. Considering recently published examples can help understand how to select and define cases effectively.

Developing a detailed case study protocol

A case study protocol outlines the procedures and general rules to be followed during the case study. This includes the data collection methods to be used, the sources of data, and the procedures for analysis. Having a detailed case study protocol ensures consistency and reliability in the study.

The protocol should also consider how to work with the people involved in the research context to grant the research team access to collecting data. As mentioned in previous sections of this guide, establishing rapport is an essential component of qualitative research as it shapes the overall potential for collecting and analyzing data.

Collecting data

Gathering data in case study research often involves multiple sources of evidence, including documents, archival records, interviews, observations, and physical artifacts. This allows for a comprehensive understanding of the case. The process for gathering data should be systematic and carefully documented to ensure the reliability and validity of the study.

Analyzing and interpreting data

The next step is analyzing the data. This involves organizing the data , categorizing it into themes or patterns , and interpreting these patterns to answer the research question. The analysis might also involve comparing the findings with prior research or theoretical propositions.

Writing the case study report

The final step is writing the case study report . This should provide a detailed description of the case, the data, the analysis process, and the findings. The report should be clear, organized, and carefully written to ensure that the reader can understand the case and the conclusions drawn from it.

Each of these steps is crucial in ensuring that the case study research is rigorous, reliable, and provides valuable insights about the case.

The type, depth, and quality of data in your study can significantly influence the validity and utility of the study. In case study research, data is usually collected from multiple sources to provide a comprehensive and nuanced understanding of the case. This section will outline the various methods of collecting data used in case study research and discuss considerations for ensuring the quality of the data.

Interviews are a common method of gathering data in case study research. They can provide rich, in-depth data about the perspectives, experiences, and interpretations of the individuals involved in the case. Interviews can be structured , semi-structured , or unstructured , depending on the research question and the degree of flexibility needed.

Observations

Observations involve the researcher observing the case in its natural setting, providing first-hand information about the case and its context. Observations can provide data that might not be revealed in interviews or documents, such as non-verbal cues or contextual information.

Documents and artifacts

Documents and archival records provide a valuable source of data in case study research. They can include reports, letters, memos, meeting minutes, email correspondence, and various public and private documents related to the case.

These records can provide historical context, corroborate evidence from other sources, and offer insights into the case that might not be apparent from interviews or observations.

Physical artifacts refer to any physical evidence related to the case, such as tools, products, or physical environments. These artifacts can provide tangible insights into the case, complementing the data gathered from other sources.

Ensuring the quality of data collection

Determining the quality of data in case study research requires careful planning and execution. It's crucial to ensure that the data is reliable, accurate, and relevant to the research question. This involves selecting appropriate methods of collecting data, properly training interviewers or observers, and systematically recording and storing the data. It also includes considering ethical issues related to collecting and handling data, such as obtaining informed consent and ensuring the privacy and confidentiality of the participants.

Data analysis

Analyzing case study research involves making sense of the rich, detailed data to answer the research question. This process can be challenging due to the volume and complexity of case study data. However, a systematic and rigorous approach to analysis can ensure that the findings are credible and meaningful. This section outlines the main steps and considerations in analyzing data in case study research.

Organizing the data

The first step in the analysis is organizing the data. This involves sorting the data into manageable sections, often according to the data source or the theme. This step can also involve transcribing interviews, digitizing physical artifacts, or organizing observational data.

Categorizing and coding the data

Once the data is organized, the next step is to categorize or code the data. This involves identifying common themes, patterns, or concepts in the data and assigning codes to relevant data segments. Coding can be done manually or with the help of software tools, and in either case, qualitative analysis software can greatly facilitate the entire coding process. Coding helps to reduce the data to a set of themes or categories that can be more easily analyzed.

Identifying patterns and themes

After coding the data, the researcher looks for patterns or themes in the coded data. This involves comparing and contrasting the codes and looking for relationships or patterns among them. The identified patterns and themes should help answer the research question.

Interpreting the data

Once patterns and themes have been identified, the next step is to interpret these findings. This involves explaining what the patterns or themes mean in the context of the research question and the case. This interpretation should be grounded in the data, but it can also involve drawing on theoretical concepts or prior research.

Verification of the data

The last step in the analysis is verification. This involves checking the accuracy and consistency of the analysis process and confirming that the findings are supported by the data. This can involve re-checking the original data, checking the consistency of codes, or seeking feedback from research participants or peers.

Like any research method , case study research has its strengths and limitations. Researchers must be aware of these, as they can influence the design, conduct, and interpretation of the study.

Understanding the strengths and limitations of case study research can also guide researchers in deciding whether this approach is suitable for their research question . This section outlines some of the key strengths and limitations of case study research.

Benefits include the following:

• Rich, detailed data: One of the main strengths of case study research is that it can generate rich, detailed data about the case. This can provide a deep understanding of the case and its context, which can be valuable in exploring complex phenomena.
• Flexibility: Case study research is flexible in terms of design , data collection , and analysis . A sufficient degree of flexibility allows the researcher to adapt the study according to the case and the emerging findings.
• Real-world context: Case study research involves studying the case in its real-world context, which can provide valuable insights into the interplay between the case and its context.
• Multiple sources of evidence: Case study research often involves collecting data from multiple sources , which can enhance the robustness and validity of the findings.

On the other hand, researchers should consider the following limitations:

• Generalizability: A common criticism of case study research is that its findings might not be generalizable to other cases due to the specificity and uniqueness of each case.
• Time and resource intensive: Case study research can be time and resource intensive due to the depth of the investigation and the amount of collected data.
• Complexity of analysis: The rich, detailed data generated in case study research can make analyzing the data challenging.
• Subjectivity: Given the nature of case study research, there may be a higher degree of subjectivity in interpreting the data , so researchers need to reflect on this and transparently convey to audiences how the research was conducted.

Being aware of these strengths and limitations can help researchers design and conduct case study research effectively and interpret and report the findings appropriately.

• Pros and Cons

What Types of Case Studies Are Out There?

Where do you find data for a case study, how do i write a psychology case study.

A case study is an in-depth study of one person, group, or event. In a case study, nearly every aspect of the subject's life and history is analyzed to seek patterns and causes of behavior. Case studies can be used in many different fields, including psychology, medicine, education, anthropology, political science, and social work.

The point of a case study is to learn as much as possible about an individual or group so that the information can be generalized to many others. Unfortunately, case studies tend to be highly subjective, and it is sometimes difficult to generalize results to a larger population.

While case studies focus on a single individual or group, they follow a format similar to other types of psychology writing. If you are writing a case study, we got you—here are some rules of APA format to reference.  

At a Glance

A case study, or an in-depth study of a person, group, or event, can be a useful research tool when used wisely. In many cases, case studies are best used in situations where it would be difficult or impossible for you to conduct an experiment. They are helpful for looking at unique situations and allow researchers to gather a lot of˜ information about a specific individual or group of people. However, it's important to be cautious of any bias we draw from them as they are highly subjective.

What Are the Benefits and Limitations of Case Studies?

A case study can have its strengths and weaknesses. Researchers must consider these pros and cons before deciding if this type of study is appropriate for their needs.

One of the greatest advantages of a case study is that it allows researchers to investigate things that are often difficult or impossible to replicate in a lab. Some other benefits of a case study:

• Allows researchers to capture information on the 'how,' 'what,' and 'why,' of something that's implemented
• Gives researchers the chance to collect information on why one strategy might be chosen over another
• Permits researchers to develop hypotheses that can be explored in experimental research

On the other hand, a case study can have some drawbacks:

• It cannot necessarily be generalized to the larger population
• Cannot demonstrate cause and effect
• It may not be scientifically rigorous
• It can lead to bias

Researchers may choose to perform a case study if they want to explore a unique or recently discovered phenomenon. Through their insights, researchers develop additional ideas and study questions that might be explored in future studies.

It's important to remember that the insights from case studies cannot be used to determine cause-and-effect relationships between variables. However, case studies may be used to develop hypotheses that can then be addressed in experimental research.

Case Study Examples

There have been a number of notable case studies in the history of psychology. Much of  Freud's work and theories were developed through individual case studies. Some great examples of case studies in psychology include:

• Anna O : Anna O. was a pseudonym of a woman named Bertha Pappenheim, a patient of a physician named Josef Breuer. While she was never a patient of Freud's, Freud and Breuer discussed her case extensively. The woman was experiencing symptoms of a condition that was then known as hysteria and found that talking about her problems helped relieve her symptoms. Her case played an important part in the development of talk therapy as an approach to mental health treatment.
• Phineas Gage : Phineas Gage was a railroad employee who experienced a terrible accident in which an explosion sent a metal rod through his skull, damaging important portions of his brain. Gage recovered from his accident but was left with serious changes in both personality and behavior.
• Genie : Genie was a young girl subjected to horrific abuse and isolation. The case study of Genie allowed researchers to study whether language learning was possible, even after missing critical periods for language development. Her case also served as an example of how scientific research may interfere with treatment and lead to further abuse of vulnerable individuals.

Such cases demonstrate how case research can be used to study things that researchers could not replicate in experimental settings. In Genie's case, her horrific abuse denied her the opportunity to learn a language at critical points in her development.

This is clearly not something researchers could ethically replicate, but conducting a case study on Genie allowed researchers to study phenomena that are otherwise impossible to reproduce.

There are a few different types of case studies that psychologists and other researchers might use:

• Collective case studies : These involve studying a group of individuals. Researchers might study a group of people in a certain setting or look at an entire community. For example, psychologists might explore how access to resources in a community has affected the collective mental well-being of those who live there.
• Descriptive case studies : These involve starting with a descriptive theory. The subjects are then observed, and the information gathered is compared to the pre-existing theory.
• Explanatory case studies : These   are often used to do causal investigations. In other words, researchers are interested in looking at factors that may have caused certain things to occur.
• Exploratory case studies : These are sometimes used as a prelude to further, more in-depth research. This allows researchers to gather more information before developing their research questions and hypotheses .
• Instrumental case studies : These occur when the individual or group allows researchers to understand more than what is initially obvious to observers.
• Intrinsic case studies : This type of case study is when the researcher has a personal interest in the case. Jean Piaget's observations of his own children are good examples of how an intrinsic case study can contribute to the development of a psychological theory.

The three main case study types often used are intrinsic, instrumental, and collective. Intrinsic case studies are useful for learning about unique cases. Instrumental case studies help look at an individual to learn more about a broader issue. A collective case study can be useful for looking at several cases simultaneously.

The type of case study that psychology researchers use depends on the unique characteristics of the situation and the case itself.

There are a number of different sources and methods that researchers can use to gather information about an individual or group. Six major sources that have been identified by researchers are:

• Archival records : Census records, survey records, and name lists are examples of archival records.
• Direct observation : This strategy involves observing the subject, often in a natural setting . While an individual observer is sometimes used, it is more common to utilize a group of observers.
• Documents : Letters, newspaper articles, administrative records, etc., are the types of documents often used as sources.
• Interviews : Interviews are one of the most important methods for gathering information in case studies. An interview can involve structured survey questions or more open-ended questions.
• Participant observation : When the researcher serves as a participant in events and observes the actions and outcomes, it is called participant observation.
• Physical artifacts : Tools, objects, instruments, and other artifacts are often observed during a direct observation of the subject.

If you have been directed to write a case study for a psychology course, be sure to check with your instructor for any specific guidelines you need to follow. If you are writing your case study for a professional publication, check with the publisher for their specific guidelines for submitting a case study.

Here is a general outline of what should be included in a case study.

Section 1: A Case History

This section will have the following structure and content:

Background information : The first section of your paper will present your client's background. Include factors such as age, gender, work, health status, family mental health history, family and social relationships, drug and alcohol history, life difficulties, goals, and coping skills and weaknesses.

Description of the presenting problem : In the next section of your case study, you will describe the problem or symptoms that the client presented with.

Describe any physical, emotional, or sensory symptoms reported by the client. Thoughts, feelings, and perceptions related to the symptoms should also be noted. Any screening or diagnostic assessments that are used should also be described in detail and all scores reported.

Your diagnosis : Provide your diagnosis and give the appropriate Diagnostic and Statistical Manual code. Explain how you reached your diagnosis, how the client's symptoms fit the diagnostic criteria for the disorder(s), or any possible difficulties in reaching a diagnosis.

Section 2: Treatment Plan

This portion of the paper will address the chosen treatment for the condition. This might also include the theoretical basis for the chosen treatment or any other evidence that might exist to support why this approach was chosen.

• Cognitive behavioral approach : Explain how a cognitive behavioral therapist would approach treatment. Offer background information on cognitive behavioral therapy and describe the treatment sessions, client response, and outcome of this type of treatment. Make note of any difficulties or successes encountered by your client during treatment.
• Humanistic approach : Describe a humanistic approach that could be used to treat your client, such as client-centered therapy . Provide information on the type of treatment you chose, the client's reaction to the treatment, and the end result of this approach. Explain why the treatment was successful or unsuccessful.
• Psychoanalytic approach : Describe how a psychoanalytic therapist would view the client's problem. Provide some background on the psychoanalytic approach and cite relevant references. Explain how psychoanalytic therapy would be used to treat the client, how the client would respond to therapy, and the effectiveness of this treatment approach.
• Pharmacological approach : If treatment primarily involves the use of medications, explain which medications were used and why. Provide background on the effectiveness of these medications and how monotherapy may compare with an approach that combines medications with therapy or other treatments.

This section of a case study should also include information about the treatment goals, process, and outcomes.

When you are writing a case study, you should also include a section where you discuss the case study itself, including the strengths and limitiations of the study. You should note how the findings of your case study might support previous research. 

In your discussion section, you should also describe some of the implications of your case study. What ideas or findings might require further exploration? How might researchers go about exploring some of these questions in additional studies?

case study , detailed description and assessment of a specific situation in the real world created for the purpose of deriving generalizations and other insights from it. A case study can be about an individual, a group of people, an organization, or an event, among other subjects.

By focusing on a specific subject in its natural setting, a case study can help improve understanding of the broader features and processes at work. Case studies are a research method used in multiple fields, including business, criminology , education , medicine and other forms of health care, anthropology , political science , psychology , and social work . Data in case studies can be both qualitative and quantitative. Unlike experiments, where researchers control and manipulate situations, case studies are considered to be “naturalistic” because subjects are studied in their natural context . ( See also natural experiment .)

The creation of a case study typically involves the following steps:

• The research question to be studied is defined, informed by existing literature and previous research. Researchers should clearly define the scope of the case, and they should compile a list of evidence to be collected as well as identify the nature of insights that they expect to gain from the case study.
• Once the case is identified, the research team is given access to the individual, organization, or situation being studied. Individuals are informed of risks associated with participation and must provide their consent , which may involve signing confidentiality or anonymity agreements.
• Researchers then collect evidence using multiple methods, which may include qualitative techniques, such as interviews, focus groups , and direct observations, as well as quantitative methods, such as surveys, questionnaires, and data audits. The collection procedures need to be well defined to ensure the relevance and accuracy of the evidence.
• The collected evidence is analyzed to come up with insights. Each data source must be reviewed carefully by itself and in the larger context of the case study so as to ensure continued relevance. At the same time, care must be taken not to force the analysis to fit (potentially preconceived) conclusions. While the eventual case study may serve as the basis for generalizations, these generalizations must be made cautiously to ensure that specific nuances are not lost in the averages.
• Finally, the case study is packaged for larger groups and publication. At this stage some information may be withheld, as in business case studies, to allow readers to draw their own conclusions. In scientific fields, the completed case study needs to be a coherent whole, with all findings and statistical relationships clearly documented.

Case studies have been used as a research method across multiple fields. They are particularly popular in the fields of law, business, and employee training; they typically focus on a problem that an individual or organization is facing. The situation is presented in considerable detail, often with supporting data, to discussion participants, who are asked to make recommendations that will solve the stated problem. The business case study as a method of instruction was made popular in the 1920s by instructors at Harvard Business School who adapted an approach used at Harvard Law School in which real-world cases were used in classroom discussions. Other business and law schools started compiling case studies as teaching aids for students. In a business school case study, students are not provided with the complete list of facts pertaining to the topic and are thus forced to discuss and compare their perspectives with those of their peers to recommend solutions.

In criminology , case studies typically focus on the lives of an individual or a group of individuals. These studies can provide particularly valuable insight into the personalities and motives of individual criminals, but they may suffer from a lack of objectivity on the part of the researchers (typically because of the researchers’ biases when working with people with a criminal history), and their findings may be difficult to generalize.

In sociology , the case-study method was developed by Frédéric Le Play in France during the 19th century. This approach involves a field worker staying with a family for a period of time, gathering data on the family members’ attitudes and interactions and on their income, expenditures, and physical possessions. Similar approaches have been used in anthropology . Such studies can sometimes continue for many years.

Case studies provide insight into situations that involve a specific entity or set of circumstances. They can be beneficial in helping to explain the causal relationships between quantitative indicators in a field of study, such as what drives a company’s market share. By introducing real-world examples, they also plunge the reader into an actual, concrete situation and make the concepts real rather than theoretical. They also help people study rare situations that they might not otherwise experience.

Because case studies are in a “naturalistic” environment , they are limited in terms of research design: researchers lack control over what they are studying, which means that the results often cannot be reproduced. Also, care must be taken to stay within the bounds of the research question on which the case study is focusing. Other limitations to case studies revolve around the data collected. It may be difficult, for instance, for researchers to organize the large volume of data that can emerge from the study, and their analysis of the data must be carefully thought through to produce scientifically valid insights. The research methodology used to generate these insights is as important as the insights themselves, for the latter need to be seen in the proper context. Taken out of context, they may lead to erroneous conclusions. Like all scientific studies, case studies need to be approached objectively; personal bias or opinion may skew the research methods as well as the results. ( See also confirmation bias .)

Business case studies in particular have been criticized for approaching a problem or situation from a narrow perspective. Students are expected to come up with solutions for a problem based on the data provided. However, in real life, the situation is typically reversed: business managers face a problem and must then look for data to help them solve it.

What is a Case Study? Definition & Examples

By Jim Frost Leave a Comment

Case Study Definition

A case study is an in-depth investigation of a single person, group, event, or community. This research method involves intensively analyzing a subject to understand its complexity and context. The richness of a case study comes from its ability to capture detailed, qualitative data that can offer insights into a process or subject matter that other research methods might miss.

A case study strives for a holistic understanding of events or situations by examining all relevant variables. They are ideal for exploring ‘how’ or ‘why’ questions in contexts where the researcher has limited control over events in real-life settings. Unlike narrowly focused experiments, these projects seek a comprehensive understanding of events or situations.

In a case study, researchers gather data through various methods such as participant observation, interviews, tests, record examinations, and writing samples. Unlike statistically-based studies that seek only quantifiable data, a case study attempts to uncover new variables and pose questions for subsequent research.

A case study is particularly beneficial when your research:

• Requires a deep, contextual understanding of a specific case.
• Needs to explore or generate hypotheses rather than test them.
• Focuses on a contemporary phenomenon within a real-life context.

Learn more about Other Types of Experimental Design .

Case Study Examples

Various fields utilize case studies, including the following:

• Social sciences : For understanding complex social phenomena.
• Business : For analyzing corporate strategies and business decisions.
• Healthcare : For detailed patient studies and medical research.
• Education : For understanding educational methods and policies.
• Law : For in-depth analysis of legal cases.

For example, consider a case study in a business setting where a startup struggles to scale. Researchers might examine the startup’s strategies, market conditions, management decisions, and competition. Interviews with the CEO, employees, and customers, alongside an analysis of financial data, could offer insights into the challenges and potential solutions for the startup. This research could serve as a valuable lesson for other emerging businesses.

See below for other examples.

Types of Case Studies

Several standard types of case studies exist that vary based on the objectives and specific research needs.

Illustrative Case Study : Descriptive in nature, these studies use one or two instances to depict a situation, helping to familiarize the unfamiliar and establish a common understanding of the topic.

Exploratory Case Study : Conducted as precursors to large-scale investigations, they assist in raising relevant questions, choosing measurement types, and identifying hypotheses to test.

Cumulative Case Study : These studies compile information from various sources over time to enhance generalization without the need for costly, repetitive new studies.

Critical Instance Case Study : Focused on specific sites, they either explore unique situations with limited generalizability or challenge broad assertions, to identify potential cause-and- effect issues.

Pros and Cons

As with any research study, case studies have a set of benefits and drawbacks.

• Provides comprehensive and detailed data.
• Offers a real-life perspective.
• Flexible and can adapt to discoveries during the study.
• Enables investigation of scenarios that are hard to assess in laboratory settings.
• Facilitates studying rare or unique cases.
• Generates hypotheses for future experimental research.
• Time-consuming and may require a lot of resources.
• Hard to generalize findings to a broader context.
• Potential for researcher bias.
• Cannot establish causality .
• Lacks scientific rigor compared to more controlled research methods .

Crafting a Good Case Study: Methodology

While case studies emphasize specific details over broad theories, they should connect to theoretical frameworks in the field. This approach ensures that these projects contribute to the existing body of knowledge on the subject, rather than standing as an isolated entity.

The following are critical steps in developing a case study:

• Define the Research Questions : Clearly outline what you want to explore. Define specific, achievable objectives.
• Select the Case : Choose a case that best suits the research questions. Consider using a typical case for general understanding or an atypical subject for unique insights.
• Data Collection : Use a variety of data sources, such as interviews, observations, documents, and archival records, to provide multiple perspectives on the issue.
• Data Analysis : Identify patterns and themes in the data.
• Report Findings : Present the findings in a structured and clear manner.

Analysts typically use thematic analysis to identify patterns and themes within the data and compare different cases.

• Qualitative Analysis : Such as coding and thematic analysis for narrative data.
• Quantitative Analysis : In cases where numerical data is involved.
• Triangulation : Combining multiple methods or data sources to enhance accuracy.

A good case study requires a balanced approach, often using both qualitative and quantitative methods.

The researcher should constantly reflect on their biases and how they might influence the research. Documenting personal reflections can provide transparency.

Avoid over-generalization. One common mistake is to overstate the implications of a case study. Remember that these studies provide an in-depth insights into a specific case and might not be widely applicable.

Don’t ignore contradictory data. All data, even that which contradicts your hypothesis, is valuable. Ignoring it can lead to skewed results.

Finally, in the report, researchers provide comprehensive insight for a case study through “thick description,” which entails a detailed portrayal of the subject, its usage context, the attributes of involved individuals, and the community environment. Thick description extends to interpreting various data, including demographic details, cultural norms, societal values, prevailing attitudes, and underlying motivations. This approach ensures a nuanced and in-depth comprehension of the case in question.

Case Study – Methods, Examples and Guide

Table of Contents

A case study is a research method that involves an in-depth examination and analysis of a particular phenomenon or case, such as an individual, organization, community, event, or situation.

It is a qualitative research approach that aims to provide a detailed and comprehensive understanding of the case being studied. Case studies typically involve multiple sources of data, including interviews, observations, documents, and artifacts, which are analyzed using various techniques, such as content analysis, thematic analysis, and grounded theory. The findings of a case study are often used to develop theories, inform policy or practice, or generate new research questions.

Types of Case Study

Types and Methods of Case Study are as follows:

Single-Case Study

A single-case study is an in-depth analysis of a single case. This type of case study is useful when the researcher wants to understand a specific phenomenon in detail.

For Example , A researcher might conduct a single-case study on a particular individual to understand their experiences with a particular health condition or a specific organization to explore their management practices. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of a single-case study are often used to generate new research questions, develop theories, or inform policy or practice.

Multiple-Case Study

A multiple-case study involves the analysis of several cases that are similar in nature. This type of case study is useful when the researcher wants to identify similarities and differences between the cases.

For Example, a researcher might conduct a multiple-case study on several companies to explore the factors that contribute to their success or failure. The researcher collects data from each case, compares and contrasts the findings, and uses various techniques to analyze the data, such as comparative analysis or pattern-matching. The findings of a multiple-case study can be used to develop theories, inform policy or practice, or generate new research questions.

Exploratory Case Study

An exploratory case study is used to explore a new or understudied phenomenon. This type of case study is useful when the researcher wants to generate hypotheses or theories about the phenomenon.

For Example, a researcher might conduct an exploratory case study on a new technology to understand its potential impact on society. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as grounded theory or content analysis. The findings of an exploratory case study can be used to generate new research questions, develop theories, or inform policy or practice.

Descriptive Case Study

A descriptive case study is used to describe a particular phenomenon in detail. This type of case study is useful when the researcher wants to provide a comprehensive account of the phenomenon.

For Example, a researcher might conduct a descriptive case study on a particular community to understand its social and economic characteristics. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of a descriptive case study can be used to inform policy or practice or generate new research questions.

Instrumental Case Study

An instrumental case study is used to understand a particular phenomenon that is instrumental in achieving a particular goal. This type of case study is useful when the researcher wants to understand the role of the phenomenon in achieving the goal.

For Example, a researcher might conduct an instrumental case study on a particular policy to understand its impact on achieving a particular goal, such as reducing poverty. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of an instrumental case study can be used to inform policy or practice or generate new research questions.

Case Study Data Collection Methods

Here are some common data collection methods for case studies:

Interviews involve asking questions to individuals who have knowledge or experience relevant to the case study. Interviews can be structured (where the same questions are asked to all participants) or unstructured (where the interviewer follows up on the responses with further questions). Interviews can be conducted in person, over the phone, or through video conferencing.

Observations

Observations involve watching and recording the behavior and activities of individuals or groups relevant to the case study. Observations can be participant (where the researcher actively participates in the activities) or non-participant (where the researcher observes from a distance). Observations can be recorded using notes, audio or video recordings, or photographs.

Documents can be used as a source of information for case studies. Documents can include reports, memos, emails, letters, and other written materials related to the case study. Documents can be collected from the case study participants or from public sources.

Surveys involve asking a set of questions to a sample of individuals relevant to the case study. Surveys can be administered in person, over the phone, through mail or email, or online. Surveys can be used to gather information on attitudes, opinions, or behaviors related to the case study.

Artifacts are physical objects relevant to the case study. Artifacts can include tools, equipment, products, or other objects that provide insights into the case study phenomenon.

How to conduct Case Study Research

Conducting a case study research involves several steps that need to be followed to ensure the quality and rigor of the study. Here are the steps to conduct case study research:

• Define the research questions: The first step in conducting a case study research is to define the research questions. The research questions should be specific, measurable, and relevant to the case study phenomenon under investigation.
• Select the case: The next step is to select the case or cases to be studied. The case should be relevant to the research questions and should provide rich and diverse data that can be used to answer the research questions.
• Collect data: Data can be collected using various methods, such as interviews, observations, documents, surveys, and artifacts. The data collection method should be selected based on the research questions and the nature of the case study phenomenon.
• Analyze the data: The data collected from the case study should be analyzed using various techniques, such as content analysis, thematic analysis, or grounded theory. The analysis should be guided by the research questions and should aim to provide insights and conclusions relevant to the research questions.
• Draw conclusions: The conclusions drawn from the case study should be based on the data analysis and should be relevant to the research questions. The conclusions should be supported by evidence and should be clearly stated.
• Validate the findings: The findings of the case study should be validated by reviewing the data and the analysis with participants or other experts in the field. This helps to ensure the validity and reliability of the findings.
• Write the report: The final step is to write the report of the case study research. The report should provide a clear description of the case study phenomenon, the research questions, the data collection methods, the data analysis, the findings, and the conclusions. The report should be written in a clear and concise manner and should follow the guidelines for academic writing.

Examples of Case Study

Here are some examples of case study research:

• The Hawthorne Studies : Conducted between 1924 and 1932, the Hawthorne Studies were a series of case studies conducted by Elton Mayo and his colleagues to examine the impact of work environment on employee productivity. The studies were conducted at the Hawthorne Works plant of the Western Electric Company in Chicago and included interviews, observations, and experiments.
• The Stanford Prison Experiment: Conducted in 1971, the Stanford Prison Experiment was a case study conducted by Philip Zimbardo to examine the psychological effects of power and authority. The study involved simulating a prison environment and assigning participants to the role of guards or prisoners. The study was controversial due to the ethical issues it raised.
• The Challenger Disaster: The Challenger Disaster was a case study conducted to examine the causes of the Space Shuttle Challenger explosion in 1986. The study included interviews, observations, and analysis of data to identify the technical, organizational, and cultural factors that contributed to the disaster.
• The Enron Scandal: The Enron Scandal was a case study conducted to examine the causes of the Enron Corporation’s bankruptcy in 2001. The study included interviews, analysis of financial data, and review of documents to identify the accounting practices, corporate culture, and ethical issues that led to the company’s downfall.
• The Fukushima Nuclear Disaster : The Fukushima Nuclear Disaster was a case study conducted to examine the causes of the nuclear accident that occurred at the Fukushima Daiichi Nuclear Power Plant in Japan in 2011. The study included interviews, analysis of data, and review of documents to identify the technical, organizational, and cultural factors that contributed to the disaster.

Application of Case Study

Case studies have a wide range of applications across various fields and industries. Here are some examples:

Business and Management

Case studies are widely used in business and management to examine real-life situations and develop problem-solving skills. Case studies can help students and professionals to develop a deep understanding of business concepts, theories, and best practices.

Case studies are used in healthcare to examine patient care, treatment options, and outcomes. Case studies can help healthcare professionals to develop critical thinking skills, diagnose complex medical conditions, and develop effective treatment plans.

Case studies are used in education to examine teaching and learning practices. Case studies can help educators to develop effective teaching strategies, evaluate student progress, and identify areas for improvement.

Social Sciences

Case studies are widely used in social sciences to examine human behavior, social phenomena, and cultural practices. Case studies can help researchers to develop theories, test hypotheses, and gain insights into complex social issues.

Law and Ethics

Case studies are used in law and ethics to examine legal and ethical dilemmas. Case studies can help lawyers, policymakers, and ethical professionals to develop critical thinking skills, analyze complex cases, and make informed decisions.

Purpose of Case Study

The purpose of a case study is to provide a detailed analysis of a specific phenomenon, issue, or problem in its real-life context. A case study is a qualitative research method that involves the in-depth exploration and analysis of a particular case, which can be an individual, group, organization, event, or community.

The primary purpose of a case study is to generate a comprehensive and nuanced understanding of the case, including its history, context, and dynamics. Case studies can help researchers to identify and examine the underlying factors, processes, and mechanisms that contribute to the case and its outcomes. This can help to develop a more accurate and detailed understanding of the case, which can inform future research, practice, or policy.

Case studies can also serve other purposes, including:

• Illustrating a theory or concept: Case studies can be used to illustrate and explain theoretical concepts and frameworks, providing concrete examples of how they can be applied in real-life situations.
• Developing hypotheses: Case studies can help to generate hypotheses about the causal relationships between different factors and outcomes, which can be tested through further research.
• Providing insight into complex issues: Case studies can provide insights into complex and multifaceted issues, which may be difficult to understand through other research methods.
• Informing practice or policy: Case studies can be used to inform practice or policy by identifying best practices, lessons learned, or areas for improvement.

Advantages of Case Study Research

There are several advantages of case study research, including:

• In-depth exploration: Case study research allows for a detailed exploration and analysis of a specific phenomenon, issue, or problem in its real-life context. This can provide a comprehensive understanding of the case and its dynamics, which may not be possible through other research methods.
• Rich data: Case study research can generate rich and detailed data, including qualitative data such as interviews, observations, and documents. This can provide a nuanced understanding of the case and its complexity.
• Holistic perspective: Case study research allows for a holistic perspective of the case, taking into account the various factors, processes, and mechanisms that contribute to the case and its outcomes. This can help to develop a more accurate and comprehensive understanding of the case.
• Theory development: Case study research can help to develop and refine theories and concepts by providing empirical evidence and concrete examples of how they can be applied in real-life situations.
• Practical application: Case study research can inform practice or policy by identifying best practices, lessons learned, or areas for improvement.
• Contextualization: Case study research takes into account the specific context in which the case is situated, which can help to understand how the case is influenced by the social, cultural, and historical factors of its environment.

Limitations of Case Study Research

There are several limitations of case study research, including:

• Limited generalizability : Case studies are typically focused on a single case or a small number of cases, which limits the generalizability of the findings. The unique characteristics of the case may not be applicable to other contexts or populations, which may limit the external validity of the research.
• Biased sampling: Case studies may rely on purposive or convenience sampling, which can introduce bias into the sample selection process. This may limit the representativeness of the sample and the generalizability of the findings.
• Subjectivity: Case studies rely on the interpretation of the researcher, which can introduce subjectivity into the analysis. The researcher’s own biases, assumptions, and perspectives may influence the findings, which may limit the objectivity of the research.
• Limited control: Case studies are typically conducted in naturalistic settings, which limits the control that the researcher has over the environment and the variables being studied. This may limit the ability to establish causal relationships between variables.
• Time-consuming: Case studies can be time-consuming to conduct, as they typically involve a detailed exploration and analysis of a specific case. This may limit the feasibility of conducting multiple case studies or conducting case studies in a timely manner.
• Resource-intensive: Case studies may require significant resources, including time, funding, and expertise. This may limit the ability of researchers to conduct case studies in resource-constrained settings.

In the field of psychology, case studies focus on a particular subject. Psychology case histories also examine human behaviors.

Case reports search for commonalities between humans. They are also used to prescribe further research. Or these studies can elaborate on a solution for a behavioral ailment.

The American Psychology Association  has a number of case studies on real-life clients. Note how the reports are more text-heavy than a business case study.

Famous psychologists such as Sigmund Freud and Anna O popularised the use of case studies in the field. They did so by regularly interviewing subjects. Their detailed observations build the field of psychology.

It is important to note that psychological studies must be conducted by professionals. Psychologists, psychiatrists and therapists should be the researchers in these cases.

What is a case study in research?

Research is a necessary part of every case study. But specific research fields are required to create studies. These fields include user research, healthcare, education, or social work.

For example, this UX Design  report examined the public perception of a client. The brand researched and implemented new visuals to improve it. The study breaks down this research through lessons learned.

Clinical reports are a necessity in the medical field. These documents are used to share knowledge with other professionals. They also help examine new or unusual diseases or symptoms.

The pandemic has led to a significant increase in research. For example,  Spectrum Health  studied the value of health systems in the pandemic. They created the study by examining community outreach.

The pandemic has significantly impacted the field of education. This has led to numerous examinations on remote studying. There have also been studies on how students react to decreased peer communication.

Social work case reports often have a community focus. They can also examine public health responses. In certain regions, social workers study disaster responses.

You now know what case studies in various fields are. In the next step of our guide, we explain the case study method.

Return to Table of Contents

A case analysis is a deep dive into a subject. To facilitate this case studies are built on interviews and observations. The below example would have been created after numerous interviews.

Case studies are largely qualitative. They analyze and describe phenomena. While some data is included, a case analysis is not quantitative.

There are a few steps in the case method. You have to start by identifying the subject of your study. Then determine what kind of research is required.

In natural sciences, case studies can take years to complete. Business reports, like this one, don’t take that long. A few weeks of interviews should be enough.

The case method will vary depending on the industry. Reports will also look different once produced.

As you will have seen, business reports are more colorful. The design is also more accessible . Healthcare and psychology reports are more text-heavy.

Designing case reports takes time and energy. So, is it worth taking the time to write them? Here are the benefits of creating case studies.

• Collects large amounts of information
• Helps formulate hypotheses
• Builds the case for further research
• Discovers new insights into a subject
• Builds brand trust and loyalty
• Engages customers through stories

For example, the business study below creates a story around a brand partnership. It makes for engaging reading. The study also shows evidence backing up the information.

We’ve shared the benefits of why studies are needed. We will also look at the limitations of creating them.

There are a few disadvantages to conducting a case analysis. The limitations will vary according to the industry.

• Responses from interviews are subjective
• Subjects may tailor responses to the researcher
• Studies can’t always be replicated
• In certain industries, analyses can take time and be expensive
• Risk of generalizing the results among a larger population

These are some of the common weaknesses of creating case reports. If you’re on the fence, look at the competition in your industry.

Other brands or professionals are building reports, like this example. In that case, you may want to do the same.

There are six common types of case reports. Depending on your industry, you might use one of these types.

Descriptive case studies

Explanatory case studies, exploratory case reports, intrinsic case studies, instrumental case studies, collective case reports.

We go into more detail about each type of study in the guide below.

When you have an existing hypothesis, you can design a descriptive study. This type of report starts with a description. The aim is to find connections between the subject being studied and a theory.

Once these connections are found, the study can conclude. The results of this type of study will usually suggest how to develop a theory further.

A study like the one below has concrete results. A descriptive report would use the quantitative data as a suggestion for researching the subject deeply.

When an incident occurs in a field, an explanation is required. An explanatory report investigates the cause of the event. It will include explanations for that cause.

The study will also share details about the impact of the event. In most cases, this report will use evidence to predict future occurrences. The results of explanatory reports are definitive.

Note that there is no room for interpretation here. The results are absolute.

The study below is a good example. It explains how one brand used the services of another. It concludes by showing definitive proof that the collaboration was successful.

Another example of this study would be in the automotive industry. If a vehicle fails a test, an explanatory study will examine why. The results could show that the failure was because of a particular part.

An explanatory report is a self-contained document. An exploratory one is only the beginning of an investigation.

Exploratory cases act as the starting point of studies. This is usually conducted as a precursor to large-scale investigations. The research is used to suggest why further investigations are needed.

An exploratory study can also be used to suggest methods for further examination.

For example, the below analysis could have found inconclusive results. In that situation, it would be the basis for an in-depth study.

Intrinsic studies are more common in the field of psychology. These reports can also be conducted in healthcare or social work.

These types of studies focus on a unique subject, such as a patient. They can sometimes study groups close to the researcher.

The aim of such studies is to understand the subject better. This requires learning their history. The researcher will also examine how they interact with their environment.

For instance, if the case study below was about a unique brand, it could be an intrinsic study.

Once the study is complete, the researcher will have developed a better understanding of a phenomenon. This phenomenon will likely not have been studied or theorized about before.

Examples of intrinsic case analysis can be found across psychology. For example, Jean Piaget’s theories on cognitive development. He established the theory from intrinsic studies into his own children.

This is another type of study seen in medical and psychology fields. Instrumental reports are created to examine more than just the primary subject.

When research is conducted for an instrumental study, it is to provide the basis for a larger phenomenon. The subject matter is usually the best example of the phenomenon. This is why it is being studied.

Take the example of the fictional brand below.

Assume it’s examining lead generation strategies. It may want to show that visual marketing is the definitive lead generation tool. The brand can conduct an instrumental case study to examine this phenomenon.

Collective studies are based on instrumental case reports. These types of studies examine multiple reports.

There are a number of reasons why collective reports are created:

• To provide evidence for starting a new study
• To find pattens between multiple instrumental reports
• To find differences in similar types of cases
• Gain a deeper understanding of a complex phenomenon
• Understand a phenomenon from diverse contexts

A researcher could use multiple reports, like the one below, to build a collective case report.

What makes a case study a case study?

A case study has a very particular research methodology. They are an in-depth study of a person or a group of individuals. They can also study a community or an organization. Case reports examine real-world phenomena within a set context.

How long should a case study be?

The length of studies depends on the industry. It also depends on the story you’re telling. Most case studies should be at least 500-1500 words long. But you can increase the length if you have more details to share.

What should you ask in a case study?

The one thing you shouldn’t ask is ‘yes’ or ‘no’ questions. Case studies are qualitative. These questions won’t give you the information you need.

Ask your client about the problems they faced. Ask them about solutions they found. Or what they think is the ideal solution. Leave room to ask them follow-up questions. This will help build out the study.

How to present a case study?

When you’re ready to present a case study, begin by providing a summary of the problem or challenge you were addressing. Follow this with an outline of the solution you implemented, and support this with the results you achieved, backed by relevant data. Incorporate visual aids like slides, graphs, and images to make your case study presentation more engaging and impactful.

Now you know what a case study means, you can begin creating one. These reports are a great tool for analyzing brands. They are also useful in a variety of other fields.

A case study research paper examines a person, place, event, condition, phenomenon, or other type of subject of analysis in order to extrapolate  key themes and results that help predict future trends, illuminate previously hidden issues that can be applied to practice, and/or provide a means for understanding an important research problem with greater clarity. A case study research paper usually examines a single subject of analysis, but case study papers can also be designed as a comparative investigation that shows relationships between two or more subjects. The methods used to study a case can rest within a quantitative, qualitative, or mixed-method investigative paradigm.

How to Approach Writing a Case Study Research Paper

General information about how to choose a topic to investigate can be found under the " Choosing a Research Problem " tab in the Organizing Your Social Sciences Research Paper writing guide. Review this page because it may help you identify a subject of analysis that can be investigated using a case study design.

However, identifying a case to investigate involves more than choosing the research problem . A case study encompasses a problem contextualized around the application of in-depth analysis, interpretation, and discussion, often resulting in specific recommendations for action or for improving existing conditions. As Seawright and Gerring note, practical considerations such as time and access to information can influence case selection, but these issues should not be the sole factors used in describing the methodological justification for identifying a particular case to study. Given this, selecting a case includes considering the following:

• The case represents an unusual or atypical example of a research problem that requires more in-depth analysis? Cases often represent a topic that rests on the fringes of prior investigations because the case may provide new ways of understanding the research problem. For example, if the research problem is to identify strategies to improve policies that support girl's access to secondary education in predominantly Muslim nations, you could consider using Azerbaijan as a case study rather than selecting a more obvious nation in the Middle East. Doing so may reveal important new insights into recommending how governments in other predominantly Muslim nations can formulate policies that support improved access to education for girls.
• The case provides important insight or illuminate a previously hidden problem? In-depth analysis of a case can be based on the hypothesis that the case study will reveal trends or issues that have not been exposed in prior research or will reveal new and important implications for practice. For example, anecdotal evidence may suggest drug use among homeless veterans is related to their patterns of travel throughout the day. Assuming prior studies have not looked at individual travel choices as a way to study access to illicit drug use, a case study that observes a homeless veteran could reveal how issues of personal mobility choices facilitate regular access to illicit drugs. Note that it is important to conduct a thorough literature review to ensure that your assumption about the need to reveal new insights or previously hidden problems is valid and evidence-based.
• The case challenges and offers a counter-point to prevailing assumptions? Over time, research on any given topic can fall into a trap of developing assumptions based on outdated studies that are still applied to new or changing conditions or the idea that something should simply be accepted as "common sense," even though the issue has not been thoroughly tested in current practice. A case study analysis may offer an opportunity to gather evidence that challenges prevailing assumptions about a research problem and provide a new set of recommendations applied to practice that have not been tested previously. For example, perhaps there has been a long practice among scholars to apply a particular theory in explaining the relationship between two subjects of analysis. Your case could challenge this assumption by applying an innovative theoretical framework [perhaps borrowed from another discipline] to explore whether this approach offers new ways of understanding the research problem. Taking a contrarian stance is one of the most important ways that new knowledge and understanding develops from existing literature.
• The case provides an opportunity to pursue action leading to the resolution of a problem? Another way to think about choosing a case to study is to consider how the results from investigating a particular case may result in findings that reveal ways in which to resolve an existing or emerging problem. For example, studying the case of an unforeseen incident, such as a fatal accident at a railroad crossing, can reveal hidden issues that could be applied to preventative measures that contribute to reducing the chance of accidents in the future. In this example, a case study investigating the accident could lead to a better understanding of where to strategically locate additional signals at other railroad crossings so as to better warn drivers of an approaching train, particularly when visibility is hindered by heavy rain, fog, or at night.
• The case offers a new direction in future research? A case study can be used as a tool for an exploratory investigation that highlights the need for further research about the problem. A case can be used when there are few studies that help predict an outcome or that establish a clear understanding about how best to proceed in addressing a problem. For example, after conducting a thorough literature review [very important!], you discover that little research exists showing the ways in which women contribute to promoting water conservation in rural communities of east central Africa. A case study of how women contribute to saving water in a rural village of Uganda can lay the foundation for understanding the need for more thorough research that documents how women in their roles as cooks and family caregivers think about water as a valuable resource within their community. This example of a case study could also point to the need for scholars to build new theoretical frameworks around the topic [e.g., applying feminist theories of work and family to the issue of water conservation].

Structure and Writing Style

The purpose of a paper in the social sciences designed around a case study is to thoroughly investigate a subject of analysis in order to reveal a new understanding about the research problem and, in so doing, contributing new knowledge to what is already known from previous studies. In applied social sciences disciplines [e.g., education, social work, public administration, etc.], case studies may also be used to reveal best practices, highlight key programs, or investigate interesting aspects of professional work.

In general, the structure of a case study research paper is not all that different from a standard college-level research paper. However, there are subtle differences you should be aware of. Here are the key elements to organizing and writing a case study research paper.

I.  Introduction

As with any research paper, your introduction should serve as a roadmap for your readers to ascertain the scope and purpose of your study . The introduction to a case study research paper, however, should not only describe the research problem and its significance, but you should also succinctly describe why the case is being used and how it relates to addressing the problem. The two elements should be linked. With this in mind, a good introduction answers these four questions:

• What is being studied? Describe the research problem and describe the subject of analysis [the case] you have chosen to address the problem. Explain how they are linked and what elements of the case will help to expand knowledge and understanding about the problem.
• Why is this topic important to investigate? Describe the significance of the research problem and state why a case study design and the subject of analysis that the paper is designed around is appropriate in addressing the problem.
• What did we know about this topic before I did this study? Provide background that helps lead the reader into the more in-depth literature review to follow. If applicable, summarize prior case study research applied to the research problem and why it fails to adequately address the problem. Describe why your case will be useful. If no prior case studies have been used to address the research problem, explain why you have selected this subject of analysis.
• How will this study advance new knowledge or new ways of understanding? Explain why your case study will be suitable in helping to expand knowledge and understanding about the research problem.

Each of these questions should be addressed in no more than a few paragraphs. Exceptions to this can be when you are addressing a complex research problem or subject of analysis that requires more in-depth background information.

II.  Literature Review

The literature review for a case study research paper is generally structured the same as it is for any college-level research paper. The difference, however, is that the literature review is focused on providing background information and  enabling historical interpretation of the subject of analysis in relation to the research problem the case is intended to address . This includes synthesizing studies that help to:

• Place relevant works in the context of their contribution to understanding the case study being investigated . This would involve summarizing studies that have used a similar subject of analysis to investigate the research problem. If there is literature using the same or a very similar case to study, you need to explain why duplicating past research is important [e.g., conditions have changed; prior studies were conducted long ago, etc.].
• Describe the relationship each work has to the others under consideration that informs the reader why this case is applicable . Your literature review should include a description of any works that support using the case to investigate the research problem and the underlying research questions.
• Identify new ways to interpret prior research using the case study . If applicable, review any research that has examined the research problem using a different research design. Explain how your use of a case study design may reveal new knowledge or a new perspective or that can redirect research in an important new direction.
• Resolve conflicts amongst seemingly contradictory previous studies . This refers to synthesizing any literature that points to unresolved issues of concern about the research problem and describing how the subject of analysis that forms the case study can help resolve these existing contradictions.
• Point the way in fulfilling a need for additional research . Your review should examine any literature that lays a foundation for understanding why your case study design and the subject of analysis around which you have designed your study may reveal a new way of approaching the research problem or offer a perspective that points to the need for additional research.
• Expose any gaps that exist in the literature that the case study could help to fill . Summarize any literature that not only shows how your subject of analysis contributes to understanding the research problem, but how your case contributes to a new way of understanding the problem that prior research has failed to do.
• Locate your own research within the context of existing literature [very important!] . Collectively, your literature review should always place your case study within the larger domain of prior research about the problem. The overarching purpose of reviewing pertinent literature in a case study paper is to demonstrate that you have thoroughly identified and synthesized prior studies in relation to explaining the relevance of the case in addressing the research problem.

III.  Method

In this section, you explain why you selected a particular case [i.e., subject of analysis] and the strategy you used to identify and ultimately decide that your case was appropriate in addressing the research problem. The way you describe the methods used varies depending on the type of subject of analysis that constitutes your case study.

If your subject of analysis is an incident or event . In the social and behavioral sciences, the event or incident that represents the case to be studied is usually bounded by time and place, with a clear beginning and end and with an identifiable location or position relative to its surroundings. The subject of analysis can be a rare or critical event or it can focus on a typical or regular event. The purpose of studying a rare event is to illuminate new ways of thinking about the broader research problem or to test a hypothesis. Critical incident case studies must describe the method by which you identified the event and explain the process by which you determined the validity of this case to inform broader perspectives about the research problem or to reveal new findings. However, the event does not have to be a rare or uniquely significant to support new thinking about the research problem or to challenge an existing hypothesis. For example, Walo, Bull, and Breen conducted a case study to identify and evaluate the direct and indirect economic benefits and costs of a local sports event in the City of Lismore, New South Wales, Australia. The purpose of their study was to provide new insights from measuring the impact of a typical local sports event that prior studies could not measure well because they focused on large "mega-events." Whether the event is rare or not, the methods section should include an explanation of the following characteristics of the event: a) when did it take place; b) what were the underlying circumstances leading to the event; and, c) what were the consequences of the event in relation to the research problem.

If your subject of analysis is a person. Explain why you selected this particular individual to be studied and describe what experiences they have had that provide an opportunity to advance new understandings about the research problem. Mention any background about this person which might help the reader understand the significance of their experiences that make them worthy of study. This includes describing the relationships this person has had with other people, institutions, and/or events that support using them as the subject for a case study research paper. It is particularly important to differentiate the person as the subject of analysis from others and to succinctly explain how the person relates to examining the research problem [e.g., why is one politician in a particular local election used to show an increase in voter turnout from any other candidate running in the election]. Note that these issues apply to a specific group of people used as a case study unit of analysis [e.g., a classroom of students].

If your subject of analysis is a place. In general, a case study that investigates a place suggests a subject of analysis that is unique or special in some way and that this uniqueness can be used to build new understanding or knowledge about the research problem. A case study of a place must not only describe its various attributes relevant to the research problem [e.g., physical, social, historical, cultural, economic, political], but you must state the method by which you determined that this place will illuminate new understandings about the research problem. It is also important to articulate why a particular place as the case for study is being used if similar places also exist [i.e., if you are studying patterns of homeless encampments of veterans in open spaces, explain why you are studying Echo Park in Los Angeles rather than Griffith Park?]. If applicable, describe what type of human activity involving this place makes it a good choice to study [e.g., prior research suggests Echo Park has more homeless veterans].

If your subject of analysis is a phenomenon. A phenomenon refers to a fact, occurrence, or circumstance that can be studied or observed but with the cause or explanation to be in question. In this sense, a phenomenon that forms your subject of analysis can encompass anything that can be observed or presumed to exist but is not fully understood. In the social and behavioral sciences, the case usually focuses on human interaction within a complex physical, social, economic, cultural, or political system. For example, the phenomenon could be the observation that many vehicles used by ISIS fighters are small trucks with English language advertisements on them. The research problem could be that ISIS fighters are difficult to combat because they are highly mobile. The research questions could be how and by what means are these vehicles used by ISIS being supplied to the militants and how might supply lines to these vehicles be cut off? How might knowing the suppliers of these trucks reveal larger networks of collaborators and financial support? A case study of a phenomenon most often encompasses an in-depth analysis of a cause and effect that is grounded in an interactive relationship between people and their environment in some way.

NOTE:   The choice of the case or set of cases to study cannot appear random. Evidence that supports the method by which you identified and chose your subject of analysis should clearly support investigation of the research problem and linked to key findings from your literature review. Be sure to cite any studies that helped you determine that the case you chose was appropriate for examining the problem.

IV.  Discussion

The main elements of your discussion section are generally the same as any research paper, but centered around interpreting and drawing conclusions about the key findings from your analysis of the case study. Note that a general social sciences research paper may contain a separate section to report findings. However, in a paper designed around a case study, it is common to combine a description of the results with the discussion about their implications. The objectives of your discussion section should include the following:

Reiterate the Research Problem/State the Major Findings Briefly reiterate the research problem you are investigating and explain why the subject of analysis around which you designed the case study were used. You should then describe the findings revealed from your study of the case using direct, declarative, and succinct proclamation of the study results. Highlight any findings that were unexpected or especially profound.

Explain the Meaning of the Findings and Why They are Important Systematically explain the meaning of your case study findings and why you believe they are important. Begin this part of the section by repeating what you consider to be your most important or surprising finding first, then systematically review each finding. Be sure to thoroughly extrapolate what your analysis of the case can tell the reader about situations or conditions beyond the actual case that was studied while, at the same time, being careful not to misconstrue or conflate a finding that undermines the external validity of your conclusions.

Relate the Findings to Similar Studies No study in the social sciences is so novel or possesses such a restricted focus that it has absolutely no relation to previously published research. The discussion section should relate your case study results to those found in other studies, particularly if questions raised from prior studies served as the motivation for choosing your subject of analysis. This is important because comparing and contrasting the findings of other studies helps support the overall importance of your results and it highlights how and in what ways your case study design and the subject of analysis differs from prior research about the topic.

Consider Alternative Explanations of the Findings Remember that the purpose of social science research is to discover and not to prove. When writing the discussion section, you should carefully consider all possible explanations revealed by the case study results, rather than just those that fit your hypothesis or prior assumptions and biases. Be alert to what the in-depth analysis of the case may reveal about the research problem, including offering a contrarian perspective to what scholars have stated in prior research if that is how the findings can be interpreted from your case.

Acknowledge the Study's Limitations You can state the study's limitations in the conclusion section of your paper but describing the limitations of your subject of analysis in the discussion section provides an opportunity to identify the limitations and explain why they are not significant. This part of the discussion section should also note any unanswered questions or issues your case study could not address. More detailed information about how to document any limitations to your research can be found here .

Suggest Areas for Further Research Although your case study may offer important insights about the research problem, there are likely additional questions related to the problem that remain unanswered or findings that unexpectedly revealed themselves as a result of your in-depth analysis of the case. Be sure that the recommendations for further research are linked to the research problem and that you explain why your recommendations are valid in other contexts and based on the original assumptions of your study.

V.  Conclusion

As with any research paper, you should summarize your conclusion in clear, simple language; emphasize how the findings from your case study differs from or supports prior research and why. Do not simply reiterate the discussion section. Provide a synthesis of key findings presented in the paper to show how these converge to address the research problem. If you haven't already done so in the discussion section, be sure to document the limitations of your case study and any need for further research.

The function of your paper's conclusion is to: 1) reiterate the main argument supported by the findings from your case study; 2) state clearly the context, background, and necessity of pursuing the research problem using a case study design in relation to an issue, controversy, or a gap found from reviewing the literature; and, 3) provide a place to persuasively and succinctly restate the significance of your research problem, given that the reader has now been presented with in-depth information about the topic.

Consider the following points to help ensure your conclusion is appropriate:

• If the argument or purpose of your paper is complex, you may need to summarize these points for your reader.
• If prior to your conclusion, you have not yet explained the significance of your findings or if you are proceeding inductively, use the conclusion of your paper to describe your main points and explain their significance.
• Move from a detailed to a general level of consideration of the case study's findings that returns the topic to the context provided by the introduction or within a new context that emerges from your case study findings.

Note that, depending on the discipline you are writing in or the preferences of your professor, the concluding paragraph may contain your final reflections on the evidence presented as it applies to practice or on the essay's central research problem. However, the nature of being introspective about the subject of analysis you have investigated will depend on whether you are explicitly asked to express your observations in this way.

Problems to Avoid

Overgeneralization One of the goals of a case study is to lay a foundation for understanding broader trends and issues applied to similar circumstances. However, be careful when drawing conclusions from your case study. They must be evidence-based and grounded in the results of the study; otherwise, it is merely speculation. Looking at a prior example, it would be incorrect to state that a factor in improving girls access to education in Azerbaijan and the policy implications this may have for improving access in other Muslim nations is due to girls access to social media if there is no documentary evidence from your case study to indicate this. There may be anecdotal evidence that retention rates were better for girls who were engaged with social media, but this observation would only point to the need for further research and would not be a definitive finding if this was not a part of your original research agenda.

Failure to Document Limitations No case is going to reveal all that needs to be understood about a research problem. Therefore, just as you have to clearly state the limitations of a general research study , you must describe the specific limitations inherent in the subject of analysis. For example, the case of studying how women conceptualize the need for water conservation in a village in Uganda could have limited application in other cultural contexts or in areas where fresh water from rivers or lakes is plentiful and, therefore, conservation is understood more in terms of managing access rather than preserving access to a scarce resource.

Failure to Extrapolate All Possible Implications Just as you don't want to over-generalize from your case study findings, you also have to be thorough in the consideration of all possible outcomes or recommendations derived from your findings. If you do not, your reader may question the validity of your analysis, particularly if you failed to document an obvious outcome from your case study research. For example, in the case of studying the accident at the railroad crossing to evaluate where and what types of warning signals should be located, you failed to take into consideration speed limit signage as well as warning signals. When designing your case study, be sure you have thoroughly addressed all aspects of the problem and do not leave gaps in your analysis that leave the reader questioning the results.

Writing Tip

At Least Five Misconceptions about Case Study Research

Social science case studies are often perceived as limited in their ability to create new knowledge because they are not randomly selected and findings cannot be generalized to larger populations. Flyvbjerg examines five misunderstandings about case study research and systematically "corrects" each one. To quote, these are:

Misunderstanding 1 :  General, theoretical [context-independent] knowledge is more valuable than concrete, practical [context-dependent] knowledge. Misunderstanding 2 :  One cannot generalize on the basis of an individual case; therefore, the case study cannot contribute to scientific development. Misunderstanding 3 :  The case study is most useful for generating hypotheses; that is, in the first stage of a total research process, whereas other methods are more suitable for hypotheses testing and theory building. Misunderstanding 4 :  The case study contains a bias toward verification, that is, a tendency to confirm the researcher’s preconceived notions. Misunderstanding 5 :  It is often difficult to summarize and develop general propositions and theories on the basis of specific case studies [p. 221].

While writing your paper, think introspectively about how you addressed these misconceptions because to do so can help you strengthen the validity and reliability of your research by clarifying issues of case selection, the testing and challenging of existing assumptions, the interpretation of key findings, and the summation of case outcomes. Think of a case study research paper as a complete, in-depth narrative about the specific properties and key characteristics of your subject of analysis applied to the research problem.

What Is a Case Study and Why You Should Use Them

Case studies can provide more insights into your business while helping you conduct further research with robust qualitative data analysis to learn more.

If you're in charge of running a company, then you're likely always looking for new ways to run your business more efficiently and increase your customer base while streamlining as many processes as possible.

Unfortunately, it can sometimes be difficult to determine how to go about implementing the proper program in order to be successful. This is why many business owners opt to conduct a case study, which can help significantly. Whether you've been struggling with brand consistency or some other problem, the right case study can identify why your problem exists as well as provide a way to rectify it.

A case study is a great tool that many businesses aren't even aware exists, and there are marketing experts like Mailchimp who can provide you with step-by-step assistance with implementing a plan with a case study. Many companies discover that not only do they need to start a blog in order to improve business, but they also need to create specific and relevant blog titles.

If your company already has a blog, then optimizing your blog posts may be helpful. Regardless of the obstacles that are preventing you from achieving all your professional goals, a case study can work wonders in helping you reverse this issue.

What is a case study?

A case study is a comprehensive report of the results of theory testing or examining emerging themes of a business in real life context. Case studies are also often used in the healthcare industry, conducting health services research with primary research interest around routinely collected healthcare data.

However, for businesses, the purpose of a case study is to help small business owners or company leaders identify the issues and conduct further research into what may be preventing success through information collection, client or customer interviews, and in-depth data analysis.

Knowing the case study definition is crucial for any business owner. By identifying the issues that are hindering a company from achieving all its goals, it's easier to make the necessary corrections to promote success through influenced data collection.

Why are case studies important?

Now that we've answered the questions, "what is a case study?" Why are case studies important? Some of the top reasons why case studies are important include:

• Understand complex issues: Even after you conduct a significant amount of market research , you might have a difficult time understanding exactly what it means. While you might have the basics down, conducting a case study can help you see how that information is applied. Then, when you see how the information can make a difference in business decisions, it could make it easier to understand complex issues.
• Collect data: A case study can also help with data tracking . A case study is a data collection method that can help you describe the information that you have available to you. Then, you can present that information in a way the reader can understand.
• Conduct evaluations: As you learn more about how to write a case study, remember that you can also use a case study to conduct evaluations of a specific situation. A case study is a great way to learn more about complex situations, and you can evaluate how various people responded in that situation. By conducting a case study evaluation, you can learn more about what has worked well, what has not, and what you might want to change in the future.
• Identify potential solutions: A case study can also help you identify solutions to potential problems. If you have an issue in your business that you are trying to solve, you may be able to take a look at a case study where someone has dealt with a similar situation in the past. For example, you may uncover data bias in a specific solution that you would like to address when you tackle the issue on your own. If you need help solving a difficult problem, a case study may be able to help you.

Remember that you can also use case studies to target your audience . If you want to show your audience that you have a significant level of expertise in a field, you may want to publish some case studies that you have handled in the past. Then, when your audience sees that you have had success in a specific area, they may be more likely to provide you with their business. In essence, case studies can be looked at as the original method of social proof, showcasing exactly how you can help someone solve their problems.

What are the benefits of writing a business case study?

Although writing a case study can seem like a tedious task, there are many benefits to conducting one through an in depth qualitative research process.

• Industry understanding: First of all, a case study can give you an in-depth understanding of your industry through a particular conceptual framework and help you identify hidden problems that are preventing you from transcending into the business world.
• Develop theories: If you decide to write a business case study, it provides you with an opportunity to develop new theories. You might have a theory about how to solve a specific problem, but you need to write a business case study to see exactly how that theory has unfolded in the past. Then, you can figure out if you want to apply your theory to a similar issue in the future.
• Evaluate interventions: When you write a business case study that focuses on a specific situation you have been through in the past, you can uncover whether that intervention was truly helpful. This can make it easier to figure out whether you want to use the same intervention in a similar situation in the future.
• Identify best practices: If you want to stay on top of the best practices in your field, conducting case studies can help by allowing you to identify patterns and trends and develop a new list of best practices that you can follow in the future.
• Versatility: Writing a case study also provides you with more versatility. If you want to expand your business applications, you need to figure out how you respond to various problems. When you run a business case study, you open the door to new opportunities, new applications, and new techniques that could help you make a difference in your business down the road.
• Solve problems: Writing a great case study can dramatically improve your chances of reversing your problem and improving your business.
• These are just a few of the biggest benefits you might experience if you decide to publish your case studies. They can be an effective tool for learning, showcasing your talents, and teaching some of your other employees. If you want to grow your audience , you may want to consider publishing some case studies.

What are the limitations of case studies?

Case studies can be a wonderful tool for any business of any size to use to gain an in-depth understanding of their clients, products, customers, or services, but there are limitations.

One limitation of case studies is the fact that, unless there are other recently published examples, there is nothing to compare them to since, most of the time, you are conducting a single, not multiple, case studies.

Another limitation is the fact that most case studies can lack scientific evidence.

Types of case studies

There are specific types of case studies to choose from, and each specific type will yield different results. Some case study types even overlap, which is sometimes more favorable, as they provide even more pertinent data.

Here are overviews of the different types of case studies, each with its own theoretical framework, so you can determine which type would be most effective for helping you meet your goals.

Explanatory case studies

Explanatory case studies are pretty straightforward, as they're not difficult to interpret. This type of case study is best if there aren't many variables involved because explanatory case studies can easily answer questions like "how" and "why" through theory development.

Exploratory case studies

An exploratory case study does exactly what its name implies: it goes into specific detail about the topic at hand in a natural, real-life context with qualitative research.

The benefits of exploratory case studies are limitless, with the main one being that it offers a great deal of flexibility. Having flexibility when writing a case study is important because you can't always predict what obstacles might arise during the qualitative research process.

Collective case studies

Collective case studies require you to study many different individuals in order to obtain usable data.

Case studies that involve an investigation of people will involve many different variables, all of which can't be predicted. Despite this fact, there are many benefits of collective case studies, including the fact that it allows an ongoing analysis of the data collected.

Intrinsic case studies

This type of study differs from the others as it focuses on the inquiry of one specific instance among many possibilities.

Many people prefer these types of case studies because it allows them to learn about the particular instance that they wish to investigate further.

Instrumental case studies

An instrumental case study is similar to an intrinsic one, as it focuses on a particular instance, whether it's a person, organization, or something different.

One thing that differentiates instrumental case studies from intrinsic ones is the fact that instrumental case studies aren't chosen merely because a person is interested in learning about a specific instance.

Tips for writing a case study

If you have decided to write case studies for your company, then you may be unsure of where to start or which type to conduct.

However, it doesn't have to be difficult or confusing to begin conducting a case study that will help you identify ways to improve your business.

Here are some helpful tips for writing your case studies:

1. Your case study must be written in the proper format

When writing a case study, the format that you should be similar to this:

Administrative summary

The executive summary is an overview of what your report will contain, written in a concise manner while providing real-life context.

Despite the fact that the executive summary should appear at the beginning of your case studies, it shouldn't be written until you've completed the entire report because if you write it before you finish the report, this summary may not be completely accurate.

Key problem statement

In this section of your case study, you will briefly describe the problem that you hope to solve by conducting the study. You will have the opportunity to elaborate on the problem that you're focusing on as you get into the breadth of the report.

Problem exploration

This part of the case study isn't as brief as the other two, and it goes into more detail about the problem at hand. Your problem exploration must include why the identified problem needs to be solved as well as the urgency of solving it.

Additionally, it must include justification for conducting the problem-solving, as the benefits must outweigh the efforts and costs.

Proposed resolution

This case study section will also be lengthier than the first two. It must include how you propose going about rectifying the problem. The "recommended solution" section must also include potential obstacles that you might experience, as well as how these will be managed.

Furthermore, you will need to list alternative solutions and explain the reason the chosen solution is best. Charts can enhance your report and make it easier to read, and provide as much proof to substantiate your claim as possible.

Overview of monetary consideration

An overview of monetary consideration is essential for all case studies, as it will be used to convince all involved parties why your project should be funded. You must successfully convince them that the cost is worth the investment it will require. It's important that you stress the necessity for this particular case study and explain the expected outcome.

Execution timeline

In the execution times of case studies, you explain how long you predict it will take to implement your study. The shorter the time it will take to implement your plan, the more apt it is to be approved. However, be sure to provide a reasonable timeline, taking into consideration any additional time that might be needed due to obstacles.

Always include a conclusion in your case study. This is where you will briefly wrap up your entire proposal, stressing the benefits of completing the data collection and data analysis in order to rectify your problem.

2. Make it clear and comprehensive

You want to write your case studies with as much clarity as possible so that every aspect of the report is understood. Be sure to double-check your grammar, spelling, punctuation, and more, as you don't want to submit a poorly-written document.

Not only would a poorly-written case study fail to prove that what you are trying to achieve is important, but it would also increase the chances that your report will be tossed aside and not taken seriously.

3. Don't rush through the process

Writing the perfect case study takes time and patience. Rushing could result in your forgetting to include information that is crucial to your entire study. Don't waste your time creating a study that simply isn't ready. Take the necessary time to perform all the research necessary to write the best case study possible.

Depending on the case study, conducting case study research could mean using qualitative methods, quantitative methods, or both. Qualitative research questions focus on non-numerical data, such as how people feel, their beliefs, their experiences, and so on.

Meanwhile, quantitative research questions focus on numerical or statistical data collection to explain causal links or get an in-depth picture.

It is also important to collect insightful and constructive feedback. This will help you better understand the outcome as well as any changes you need to make to future case studies. Consider using formal and informal ways to collect feedback to ensure that you get a range of opinions and perspectives.

4. Be confident in your theory development

While writing your case study or conducting your formal experimental investigation, you should have confidence in yourself and what you're proposing in your report. If you took the time to gather all the pertinent data collected to complete the report, don't second-guess yourself or doubt your abilities. If you believe your report will be amazing, then it likely will be.

5. Case studies and all qualitative research are long

It's expected that multiple case studies are going to be incredibly boring, and there is no way around this. However, it doesn't mean you can choose your language carefully in order to keep your audience as engaged as possible.

If your audience loses interest in your case study at the beginning, for whatever reason, then this increases the likelihood that your case study will not be funded.

Case study examples

If you want to learn more about how to write a case study, it might be beneficial to take a look at a few case study examples. Below are a few interesting case study examples you may want to take a closer look at.

• Phineas Gage by John Martin Marlow : One of the most famous case studies comes from the medical field, and it is about the story of Phineas Gage, a man who had a railroad spike driven through his head in 1848. As he was working on a railroad, an explosive charge went off prematurely, sending a railroad rod through his head. Even though he survived this incident, he lost his left eye. However, Phineas Gage was studied extensively over the years because his experiences had a significant, lasting impact on his personality. This served as a case study because his injury showed different parts of the brain have different functions.
• Kitty Genovese and the bystander effect : This is a tragic case study that discusses the murder of Kitty Genovese, a woman attacked and murdered in Queens, New York City. Shockingly, while numerous neighbors watched the scene, nobody called for help because they assumed someone else would. This case study helped to define the bystander effect, which is when a person fails to intervene during an emergency because other people are around.
• Henry Molaison and the study of memory : Henry Molaison lost his memory and suffered from debilitating amnesia. He suffered from childhood epilepsy, and medical professionals attempted to remove the part of his brain that was causing his seizures. He had a portion of his brain removed, but it completely took away his ability to hold memories. Even though he went on to live until the age of 82, he was always forced to live in the present moment, as he was completely unable to form new memories.

Case study FAQs

When should you do a case study.

There are several scenarios when conducting a case study can be beneficial. Case studies are often used when there's a "why" or "how" question that needs to be answered. Case studies are also beneficial when trying to understand a complex phenomenon, there's limited research on a topic, or when you're looking for practical solutions to a problem.

How can case study results be used to make business decisions?

You can use the results from a case study to make future business decisions if you find yourself in a similar situation. As you assess the results of a case study, you can identify best practices, evaluate the effectiveness of an intervention, generate new and creative ideas, or get a better understanding of customer needs.

How are case studies different from other research methodologies?

When compared to other research methodologies, such as experimental or qualitative research methodology, a case study does not require a representative sample. For example, if you are performing quantitative research, you have a lot of subjects that expand your sample size. If you are performing experimental research, you may have a random sample in front of you. A case study is usually designed to deliberately focus on unusual situations, which allows it to shed new light on a specific business research problem.

Writing multiple case studies for your business

If you're feeling overwhelmed by the idea of writing a case study and it seems completely foreign, then you aren't alone. Writing a case study for a business is a very big deal, but fortunately, there is help available because an example of a case study doesn't always help.

Mailchimp, a well-known marketing company that provides comprehensive marketing support for all sorts of businesses, can assist you with your case study, or you can review one of their own recently published examples.

What is it?

Case study is a research methodology, typically seen in social and life sciences. There is no one definition of case study research. 1 However, very simply… ‘a case study can be defined as an intensive study about a person, a group of people or a unit, which is aimed to generalize over several units’. 1 A case study has also been described as an intensive, systematic investigation of a single individual, group, community or some other unit in which the researcher examines in-depth data relating to several variables. 2

Often there are several similar cases to consider such as educational or social service programmes that are delivered from a number of locations. Although similar, they are complex and have unique features. In these circumstances, the evaluation of several, similar cases will provide a better answer to a research question than if only one case is examined, hence the multiple-case study. Stake asserts that the cases are grouped and viewed as one entity, called the quintain . 6  ‘We study what is similar and different about the cases to understand the quintain better’. 6

The steps when using case study methodology are the same as for other types of research. 6 The first step is defining the single case or identifying a group of similar cases that can then be incorporated into a multiple-case study. A search to determine what is known about the case(s) is typically conducted. This may include a review of the literature, grey literature, media, reports and more, which serves to establish a basic understanding of the cases and informs the development of research questions. Data in case studies are often, but not exclusively, qualitative in nature. In multiple-case studies, analysis within cases and across cases is conducted. Themes arise from the analyses and assertions about the cases as a whole, or the quintain, emerge. 6

Benefits and limitations of case studies

If a researcher wants to study a specific phenomenon arising from a particular entity, then a single-case study is warranted and will allow for a in-depth understanding of the single phenomenon and, as discussed above, would involve collecting several different types of data. This is illustrated in example 1 below.

Using a multiple-case research study allows for a more in-depth understanding of the cases as a unit, through comparison of similarities and differences of the individual cases embedded within the quintain. Evidence arising from multiple-case studies is often stronger and more reliable than from single-case research. Multiple-case studies allow for more comprehensive exploration of research questions and theory development. 6

Despite the advantages of case studies, there are limitations. The sheer volume of data is difficult to organise and data analysis and integration strategies need to be carefully thought through. There is also sometimes a temptation to veer away from the research focus. 2 Reporting of findings from multiple-case research studies is also challenging at times, 1 particularly in relation to the word limits for some journal papers.

Examples of case studies

Example 1: nurses’ paediatric pain management practices.

One of the authors of this paper (AT) has used a case study approach to explore nurses’ paediatric pain management practices. This involved collecting several datasets:

Observational data to gain a picture about actual pain management practices.

Questionnaire data about nurses’ knowledge about paediatric pain management practices and how well they felt they managed pain in children.

Questionnaire data about how critical nurses perceived pain management tasks to be.

These datasets were analysed separately and then compared 7–9 and demonstrated that nurses’ level of theoretical did not impact on the quality of their pain management practices. 7 Nor did individual nurse’s perceptions of how critical a task was effect the likelihood of them carrying out this task in practice. 8 There was also a difference in self-reported and observed practices 9 ; actual (observed) practices did not confirm to best practice guidelines, whereas self-reported practices tended to.

Example 2: quality of care for complex patients at Nurse Practitioner-Led Clinics (NPLCs)

The other author of this paper (RH) has conducted a multiple-case study to determine the quality of care for patients with complex clinical presentations in NPLCs in Ontario, Canada. 10 Five NPLCs served as individual cases that, together, represented the quatrain. Three types of data were collected including:

Review of documentation related to the NPLC model (media, annual reports, research articles, grey literature and regulatory legislation).

Interviews with nurse practitioners (NPs) practising at the five NPLCs to determine their perceptions of the impact of the NPLC model on the quality of care provided to patients with multimorbidity.

Chart audits conducted at the five NPLCs to determine the extent to which evidence-based guidelines were followed for patients with diabetes and at least one other chronic condition.

The three sources of data collected from the five NPLCs were analysed and themes arose related to the quality of care for complex patients at NPLCs. The multiple-case study confirmed that nurse practitioners are the primary care providers at the NPLCs, and this positively impacts the quality of care for patients with multimorbidity. Healthcare policy, such as lack of an increase in salary for NPs for 10 years, has resulted in issues in recruitment and retention of NPs at NPLCs. This, along with insufficient resources in the communities where NPLCs are located and high patient vulnerability at NPLCs, have a negative impact on the quality of care. 10

These examples illustrate how collecting data about a single case or multiple cases helps us to better understand the phenomenon in question. Case study methodology serves to provide a framework for evaluation and analysis of complex issues. It shines a light on the holistic nature of nursing practice and offers a perspective that informs improved patient care.

Case Study | Definition, Examples & Methods

Published on 5 May 2022 by Shona McCombes . Revised on 30 January 2023.

A case study is a detailed study of a specific subject, such as a person, group, place, event, organisation, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research.

A case study research design usually involves qualitative methods , but quantitative methods are sometimes also used. Case studies are good for describing , comparing, evaluating, and understanding different aspects of a research problem .

Table of contents

When to do a case study, step 1: select a case, step 2: build a theoretical framework, step 3: collect your data, step 4: describe and analyse the case.

A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case.

Case studies are often a good choice in a thesis or dissertation . They keep your project focused and manageable when you don’t have the time or resources to do large-scale research.

You might use just one complex case study where you explore a single subject in depth, or conduct multiple case studies to compare and illuminate different aspects of your research problem.

Prevent plagiarism, run a free check.

Once you have developed your problem statement and research questions , you should be ready to choose the specific case that you want to focus on. A good case study should have the potential to:

• Provide new or unexpected insights into the subject
• Challenge or complicate existing assumptions and theories
• Propose practical courses of action to resolve a problem
• Open up new directions for future research

Unlike quantitative or experimental research, a strong case study does not require a random or representative sample. In fact, case studies often deliberately focus on unusual, neglected, or outlying cases which may shed new light on the research problem.

If you find yourself aiming to simultaneously investigate and solve an issue, consider conducting action research . As its name suggests, action research conducts research and takes action at the same time, and is highly iterative and flexible. 

However, you can also choose a more common or representative case to exemplify a particular category, experience, or phenomenon.

While case studies focus more on concrete details than general theories, they should usually have some connection with theory in the field. This way the case study is not just an isolated description, but is integrated into existing knowledge about the topic. It might aim to:

• Exemplify a theory by showing how it explains the case under investigation
• Expand on a theory by uncovering new concepts and ideas that need to be incorporated
• Challenge a theory by exploring an outlier case that doesn’t fit with established assumptions

To ensure that your analysis of the case has a solid academic grounding, you should conduct a literature review of sources related to the topic and develop a theoretical framework . This means identifying key concepts and theories to guide your analysis and interpretation.

There are many different research methods you can use to collect data on your subject. Case studies tend to focus on qualitative data using methods such as interviews, observations, and analysis of primary and secondary sources (e.g., newspaper articles, photographs, official records). Sometimes a case study will also collect quantitative data .

The aim is to gain as thorough an understanding as possible of the case and its context.

In writing up the case study, you need to bring together all the relevant aspects to give as complete a picture as possible of the subject.

How you report your findings depends on the type of research you are doing. Some case studies are structured like a standard scientific paper or thesis, with separate sections or chapters for the methods , results , and discussion .

Others are written in a more narrative style, aiming to explore the case from various angles and analyse its meanings and implications (for example, by using textual analysis or discourse analysis ).

In all cases, though, make sure to give contextual details about the case, connect it back to the literature and theory, and discuss how it fits into wider patterns or debates.

Writing a Case Study

What is a case study?

A Case study is: 

• An in-depth research design that primarily uses a qualitative methodology but sometimes​​ includes quantitative methodology.
• Used to examine an identifiable problem confirmed through research.
• Used to investigate an individual, group of people, organization, or event.
• Used to mostly answer "how" and "why" questions.

What are the different types of case studies?

Note: These are the primary case studies. As you continue to research and learn

about case studies you will begin to find a robust list of different types. 

Who are your case study participants?

What is triangulation ? 

Validity and credibility are an essential part of the case study. Therefore, the researcher should include triangulation to ensure trustworthiness while accurately reflecting what the researcher seeks to investigate.

How to write a Case Study?

When developing a case study, there are different ways you could present the information, but remember to include the five parts for your case study.

On This Page:

Case studies are in-depth investigations of a person, group, event, or community. Typically, data is gathered from various sources using several methods (e.g., observations & interviews).

The case study research method originated in clinical medicine (the case history, i.e., the patient’s personal history). In psychology, case studies are often confined to the study of a particular individual.

The information is mainly biographical and relates to events in the individual’s past (i.e., retrospective), as well as to significant events that are currently occurring in his or her everyday life.

The case study is not a research method, but researchers select methods of data collection and analysis that will generate material suitable for case studies.

Freud (1909a, 1909b) conducted very detailed investigations into the private lives of his patients in an attempt to both understand and help them overcome their illnesses.

This makes it clear that the case study is a method that should only be used by a psychologist, therapist, or psychiatrist, i.e., someone with a professional qualification.

There is an ethical issue of competence. Only someone qualified to diagnose and treat a person can conduct a formal case study relating to atypical (i.e., abnormal) behavior or atypical development.

 Famous Case Studies

• Anna O – One of the most famous case studies, documenting psychoanalyst Josef Breuer’s treatment of “Anna O” (real name Bertha Pappenheim) for hysteria in the late 1800s using early psychoanalytic theory.
• Little Hans – A child psychoanalysis case study published by Sigmund Freud in 1909 analyzing his five-year-old patient Herbert Graf’s house phobia as related to the Oedipus complex.
• Bruce/Brenda – Gender identity case of the boy (Bruce) whose botched circumcision led psychologist John Money to advise gender reassignment and raise him as a girl (Brenda) in the 1960s.
• Genie Wiley – Linguistics/psychological development case of the victim of extreme isolation abuse who was studied in 1970s California for effects of early language deprivation on acquiring speech later in life.
• Phineas Gage – One of the most famous neuropsychology case studies analyzes personality changes in railroad worker Phineas Gage after an 1848 brain injury involving a tamping iron piercing his skull.

Clinical Case Studies

• Studying the effectiveness of psychotherapy approaches with an individual patient
• Assessing and treating mental illnesses like depression, anxiety disorders, PTSD
• Neuropsychological cases investigating brain injuries or disorders

Child Psychology Case Studies

• Studying psychological development from birth through adolescence
• Cases of learning disabilities, autism spectrum disorders, ADHD
• Effects of trauma, abuse, deprivation on development

Types of Case Studies

• Explanatory case studies : Used to explore causation in order to find underlying principles. Helpful for doing qualitative analysis to explain presumed causal links.
• Exploratory case studies : Used to explore situations where an intervention being evaluated has no clear set of outcomes. It helps define questions and hypotheses for future research.
• Descriptive case studies : Describe an intervention or phenomenon and the real-life context in which it occurred. It is helpful for illustrating certain topics within an evaluation.
• Multiple-case studies : Used to explore differences between cases and replicate findings across cases. Helpful for comparing and contrasting specific cases.
• Intrinsic : Used to gain a better understanding of a particular case. Helpful for capturing the complexity of a single case.
• Collective : Used to explore a general phenomenon using multiple case studies. Helpful for jointly studying a group of cases in order to inquire into the phenomenon.

Where Do You Find Data for a Case Study?

There are several places to find data for a case study. The key is to gather data from multiple sources to get a complete picture of the case and corroborate facts or findings through triangulation of evidence. Most of this information is likely qualitative (i.e., verbal description rather than measurement), but the psychologist might also collect numerical data.

1. Primary sources

• Interviews – Interviewing key people related to the case to get their perspectives and insights. The interview is an extremely effective procedure for obtaining information about an individual, and it may be used to collect comments from the person’s friends, parents, employer, workmates, and others who have a good knowledge of the person, as well as to obtain facts from the person him or herself.
• Observations – Observing behaviors, interactions, processes, etc., related to the case as they unfold in real-time.
• Documents & Records – Reviewing private documents, diaries, public records, correspondence, meeting minutes, etc., relevant to the case.

2. Secondary sources

• News/Media – News coverage of events related to the case study.
• Academic articles – Journal articles, dissertations etc. that discuss the case.
• Government reports – Official data and records related to the case context.
• Books/films – Books, documentaries or films discussing the case.

3. Archival records

Searching historical archives, museum collections and databases to find relevant documents, visual/audio records related to the case history and context.

Public archives like newspapers, organizational records, photographic collections could all include potentially relevant pieces of information to shed light on attitudes, cultural perspectives, common practices and historical contexts related to psychology.

4. Organizational records

Organizational records offer the advantage of often having large datasets collected over time that can reveal or confirm psychological insights.

Of course, privacy and ethical concerns regarding confidential data must be navigated carefully.

However, with proper protocols, organizational records can provide invaluable context and empirical depth to qualitative case studies exploring the intersection of psychology and organizations.

• Organizational/industrial psychology research : Organizational records like employee surveys, turnover/retention data, policies, incident reports etc. may provide insight into topics like job satisfaction, workplace culture and dynamics, leadership issues, employee behaviors etc.
• Clinical psychology : Therapists/hospitals may grant access to anonymized medical records to study aspects like assessments, diagnoses, treatment plans etc. This could shed light on clinical practices.
• School psychology : Studies could utilize anonymized student records like test scores, grades, disciplinary issues, and counseling referrals to study child development, learning barriers, effectiveness of support programs, and more.

How do I Write a Case Study in Psychology?

Follow specified case study guidelines provided by a journal or your psychology tutor. General components of clinical case studies include: background, symptoms, assessments, diagnosis, treatment, and outcomes. Interpreting the information means the researcher decides what to include or leave out. A good case study should always clarify which information is the factual description and which is an inference or the researcher’s opinion.

1. Introduction

• Provide background on the case context and why it is of interest, presenting background information like demographics, relevant history, and presenting problem.
• Compare briefly to similar published cases if applicable. Clearly state the focus/importance of the case.

2. Case Presentation

• Describe the presenting problem in detail, including symptoms, duration,and impact on daily life.
• Include client demographics like age and gender, information about social relationships, and mental health history.
• Describe all physical, emotional, and/or sensory symptoms reported by the client.
• Use patient quotes to describe the initial complaint verbatim. Follow with full-sentence summaries of relevant history details gathered, including key components that led to a working diagnosis.
• Summarize clinical exam results, namely orthopedic/neurological tests, imaging, lab tests, etc. Note actual results rather than subjective conclusions. Provide images if clearly reproducible/anonymized.
• Clearly state the working diagnosis or clinical impression before transitioning to management.

3. Management and Outcome

• Indicate the total duration of care and number of treatments given over what timeframe. Use specific names/descriptions for any therapies/interventions applied.
• Present the results of the intervention,including any quantitative or qualitative data collected.
• For outcomes, utilize visual analog scales for pain, medication usage logs, etc., if possible. Include patient self-reports of improvement/worsening of symptoms. Note the reason for discharge/end of care.

4. Discussion

• Analyze the case, exploring contributing factors, limitations of the study, and connections to existing research.
• Analyze the effectiveness of the intervention,considering factors like participant adherence, limitations of the study, and potential alternative explanations for the results.
• Identify any questions raised in the case analysis and relate insights to established theories and current research if applicable. Avoid definitive claims about physiological explanations.
• Offer clinical implications, and suggest future research directions.

5. Additional Items

• Thank specific assistants for writing support only. No patient acknowledgments.
• References should directly support any key claims or quotes included.
• Use tables/figures/images only if substantially informative. Include permissions and legends/explanatory notes.
• Provides detailed (rich qualitative) information.
• Provides insight for further research.
• Permitting investigation of otherwise impractical (or unethical) situations.

Case studies allow a researcher to investigate a topic in far more detail than might be possible if they were trying to deal with a large number of research participants (nomothetic approach) with the aim of ‘averaging’.

Because of their in-depth, multi-sided approach, case studies often shed light on aspects of human thinking and behavior that would be unethical or impractical to study in other ways.

Research that only looks into the measurable aspects of human behavior is not likely to give us insights into the subjective dimension of experience, which is important to psychoanalytic and humanistic psychologists.

Case studies are often used in exploratory research. They can help us generate new ideas (that might be tested by other methods). They are an important way of illustrating theories and can help show how different aspects of a person’s life are related to each other.

The method is, therefore, important for psychologists who adopt a holistic point of view (i.e., humanistic psychologists ).

Limitations

• Lacking scientific rigor and providing little basis for generalization of results to the wider population.
• Researchers’ own subjective feelings may influence the case study (researcher bias).
• Difficult to replicate.
• Time-consuming and expensive.
• The volume of data, together with the time restrictions in place, impacted the depth of analysis that was possible within the available resources.

Because a case study deals with only one person/event/group, we can never be sure if the case study investigated is representative of the wider body of “similar” instances. This means the conclusions drawn from a particular case may not be transferable to other settings.

Because case studies are based on the analysis of qualitative (i.e., descriptive) data , a lot depends on the psychologist’s interpretation of the information she has acquired.

This means that there is a lot of scope for Anna O , and it could be that the subjective opinions of the psychologist intrude in the assessment of what the data means.

For example, Freud has been criticized for producing case studies in which the information was sometimes distorted to fit particular behavioral theories (e.g., Little Hans ).

This is also true of Money’s interpretation of the Bruce/Brenda case study (Diamond, 1997) when he ignored evidence that went against his theory.

What is a case study?

An effective case study is a great way to show potential clients, customers, and stakeholders how valuable your product or service is by explaining how your business solved a particularly challenging client problem.

Marketing case studies examine a single client situation in-depth and provide a detailed analysis of how your organization resolved the challenge.

The best case studies not only tell a story about your company but also contain some hard measurable metrics. This allows you to highlight your successes in a way that will make an ideal potential customer become your customer. Essentially, a case study is an effective way to learn about your business and a great marketing tool.

When looking for potential projects to use for a case study, look for ones that:

• Involved a particular challenge that required a unique set of skills that your company possesses
• Received special awards, press coverage or accolades
• Involved a high profile project
• Involved a well-known (preferably Fortune 500) brand or company

The most important element of your case study is that it must show a real-life example to relate to your target client. While a good case study showcases your company, a great case study makes the reader want to start a conversation with you.

What information should be included in a case study?

The first thing to consider is who will be reading your case studies. Messages and their delivery resonate differently, depending on who is on the receiving end. For example, a thirty-something software entrepreneur will measure success differently than a fifty-something CEO of a large corporation. Understanding your target audience will help you tell your case study in a way that will effectively speak to them.

When gathering information for your case study, interview happy customers and ask questions to your potential case study subject that align with the story you are trying to tell. No case study will be the same, and your questions will vary from client to client.

Before you contact the customer, consider interview questions so you have an idea of what you need to produce a compelling case study demonstrating your potential to succeed.

At the end of the information-gathering process, you should have a solid understanding of the following to outline how your product was the best solution for the customers’ particular challenge:

• The client’s initial challenge
• Why did the client choose your company
• Your company’s approach to the problem
• The solution and implementation process
• The results and final measures of success

Some questions to ask your client during the initial interview:

• Can you give a brief description of your company?
• How did you first hear about our product or service?
• What challenges or pain points prompted using our product? 
• What were you looking for in a solution to your problem? 
• Did you have any roadblocks while using our product? 

Don’t forget to talk to your colleagues and get their perspectives on the project when writing your case study. You may also want to include some quotes from internal stakeholders or project leads to make an even more compelling case study.

How do you write a case study?

When writing a case study, make sure you know who you’re talking to. Your audience, i.e. who would be interested in your product or service, should be your main focus when you create a case study. Once you’ve compiled your facts, format the story so that it will appeal to potential customers.

The format and content of case study templates vary, but in general, your business case study should look like a strong landing page: brief, pictorial, and engaging.

Xtensio’s case study template includes instructional copy to show you everything you need to know to create a real-life example of your company’s strengths. The template is organized into sections and modules designed to make your case study flow like a well-planned story and we’ve broken the template into three main sections: the snapshot, the body and the footer. 

The Snapshot

This section is designed to give a quick overview of your story and prompt readers to want to learn more. Consider it an executive summary, a book cover, or a brief description in an online store. It should have enough information to grab a potential customer’s attention, but not so much that they will stop reading. Include client details, the project name, and a brief description of the problem, as well as quantitative metrics that demonstrate your accomplishment.

You can also include the date the case study was originally published here to help potential customers identify if your product or service is a good fit for them right now. 

This section is the meat of your case study and will focus on customer results. Like any good story, it will have a beginning, a middle and an end. Classic western storytelling uses a pretty standard formula that includes a problem, the approach taken to solve it, the solution and the end results. The body of Xtensio’s case study template is divided into four key areas that align to these story elements: the Challenge, the Approach, the Solution and the Results. Here, make sure you explain using your product for a certain use case and describe how your service helped the client.

To close your case study, end with a short paragraph about who your company is, as well as your contact information. This is handy if your business case study becomes separated from your company’s website information somehow.

If you plan on sharing the case study online, make sure to add the links to your website and social media handles, using our social media module. If you are planning to print, then don’t forget to spell out the name of your website and/or add a contact phone number and email address.

Invite feedback and participation by your colleagues and the client by inviting them to collaborate on the case study template in real-time. Once you are satisfied with your case study, you can add it to your website, share it on your social channels, use it in presentations, or send out emails to potential clients. You can also download a pdf version that can be printed and shared.

Heuristic evaluation: Definition, case study, template

Imagine yourself faced with the challenge of assembling a tricky puzzle but not knowing where to start. Elements such as logical reasoning and meticulous attention to detail become essential, requiring an approach that goes beyond the surface level to achieve effectiveness. When evaluating the user experience of an interface, it is no different.

In this article, we will cover the fundamental concepts of heuristic evaluation, how to properly perform a heuristic evaluation, and the positive effects it can bring to your UX design process. Let’s learn how you can solve challenges with heuristic evaluation.

What is heuristic evaluation?

The heuristic evaluation principles, understanding nielsen’s 10 usability heuristics, essential steps in heuristic evaluation, prioritization criteria in the analysis of usability problems, communicating heuristic evaluation results effectively, dropbox’s heuristic evaluation approach, incorporating heuristic evaluation into the ux process.

The heuristic evaluation method’s main goal is to evaluate the usability quality of an interface based on a set of principles, based on UX best practices. From the identification of the problems, it is possible to provide practical recommendations and consequently improve the user experience.

So where did heuristic evaluation come from, and how do we use these principles? Read on.

Heuristic evaluation was created by Jakob Nielsen, recognized worldwide for his significant contributions to the field of UX. The method created by Nielsen is based on a set of heuristics from human-computer interaction (HCI) and psychology to inspect the usability of user interfaces.

Therefore, Nielsen’s 10 usability heuristics make up the principles of heuristic evaluation by establishing carefully established foundations. These foundations serve as a practical guide to cover the main usability problems of projects. These heuristics work as cognitive shortcuts used by the brain for efficient decision making, especially in redesign projects. Heuristics also help to complement the UX process when understanding user problems and supporting UX research and evaluation.

When you are getting ready to conduct a heuristic evaluation, the first step is to set clear goals. Then, during the evaluation, you should make notes on what you find considering usability issues, always based on the criteria. Once this is done, you can prepare a report that might include information on which issues to tackle first, which makes the evaluation even better. All these steps matter because they help make sure interfaces match what users want and expect, leading to better interactions overall.

Preparation for the heuristic evaluation: Defining usability objectives and criteria

As with the puzzle example in the intro, fully understanding the problem is critical to applying heuristic evaluation effectively. Thus, during the preparation phase, you need to establish the evaluation criteria, also defining how these criteria will be evaluated.

Select evaluators based on their experience. By involving a diverse set of evaluators, you can obtain different perspectives on the same challenge. Although an expert is able to point out most of the problems in a heuristic evaluation, collaboration is essential to generate more comprehensive recommendations.

Although it follows a set of heuristics, the evaluation is less formal and less expensive than a user test, making it faster and easier to conduct. Therefore, heuristic evaluation can be performed in the early stages of design and development when making changes is more cost effective.

Nielsen’s usability heuristics are like a tactical set for methodically making things work, providing valuable clues that designers and creators follow to piece together the usability puzzle. These heuristics act as master guides, helping us intelligently fit each piece of the puzzle together so that everything makes sense and is easy to understand to create amazing experiences in the products and websites we use.

Over 200k developers and product managers use LogRocket to create better digital experiences

Here are Nielsen’s 10 usability heuristics, each with its own relevance and purpose:

1. System status visibility

Continuously inform the user about what is happening.

2. Correspondence between the system and the real world

Use words and concepts familiar to the user.

3. User control and freedom

Allow users to undo actions and explore the system without fear of making mistakes.

4. Consistency and standards

Maintain a consistent design throughout the system, so users can apply what they learned in one part to the rest.

5. Error prevention

Design in a manner that prevents users from committing mistakes or provides means to easily correct wrong decisions.

6. Recognition instead of memorization

Provide contextual hints and tips to help users accomplish tasks without needing to remember specific information.

7. Flexibility and efficiency of use

Allow users to customize keyboard shortcuts or create custom profiles to streamline their interactions.

8. Aesthetics and minimalist design

Keep the design clean and simple, focusing on the most relevant information to avoid overwhelming users using proper spacing, colors, and typography.

9. Help and documentation

Provide helpful and accessible support in case users need extra guidance.

10. User feedback

Give immediate feedback to users when they take an action.

Together, these pieces of the usability heuristics puzzle help us build a complete picture of digital experiences. Thus, by following these guidelines, evaluators can identify problems and prioritize them for correction at the evaluation stage.

In the evaluation phase, evaluators should look at the product or system interface and document any usability issues based on heuristics. By using heuristics consistently across different parts of the interface, it is still possible to balance conflicting heuristics to find optimal design solutions.

There may be challenges during the evaluation phase, which is why it is important that evaluators suggest strategies to overcome them from the definition of priorities. Evaluators should therefore, in consensus, discuss how these heuristics can be applied to identify and address usability problems.

One of the interesting ways to do heuristic evaluation is through real-time collaboration tools like Miro. On the template below, you will be able to collaborate in real-time to conduct heuristic evaluations of your project with your team, evaluating the problems by criteria and dividing them by colors, based on the level of complexity to be solved.

You can download the Miro Heuristic Evaluation template for free .

After performing a heuristic assessment, evaluators should analyze the findings and prioritize usability issues, trying to identify the underlying causes of usability issues rather than just addressing surface symptoms.

Usability issues discovered during the assessment can be given severity ratings to prioritize fixes.

Below is an example of categorization by severity according to the challenge presented:

• High severity : Prevents the user from performing one or more tasks
• Medium severity : Requires user effort and affects performance
• Low severity : May be noticeable to the user but does not impede execution or performance

The classification will help the team to have greater clarity regarding what is most relevant to be faced considering the impact on the user experience. By prioritizing the most critical issues based on their impact on the user experience, it will be easier to effectively allocate them throughout the project.

Finally, during the reporting phase, evaluators should present their findings and recommendations to stakeholders and facilitate discussions on identified issues.

Evaluators typically conduct multiple iterations of the assessment to uncover different issues in subsequent rounds based on the need for the project and the issues identified.

Heuristic evaluation provides qualitative data, making it important to interpret the results with a deeper understanding of user behavior. When reporting and communicating the results of a heuristic assessment, assessors should follow best practices by presenting findings in visual representations that are easy to read and understand, and that highlight key findings, whether using interactive boards, tables or other visuals.

Problem descriptions should be clear and concise so they can be actionable. Instead of generating generic problems, for example, break the problems into distinct parts to be easier to deal with. If necessary, try to analyze the interface component and its details, thinking not only analytically in an abstract way but also understanding that that problem will be solved by a UX Designer, considering all its elements. In this scenario, a well-applied context makes all the difference.

It is also important to involve stakeholders and facilitate discussions around identified issues. As a popular saying goes: a problem communicated is a problem half solved.

The Dropbox team really nails it when it comes to giving users a smooth and user friendly experience. Let’s dive into a few ways they have put these heuristic evaluation principles to work in their platform:

Dropbox keeps things clear by using concise labels to show the status of your uploaded files. They also incorporate a convenient progress bar that provides a time estimate for the completion of the upload. This real-time feedback keeps you informed about the ongoing status of your uploads on the platform:

The ease of moving, deleting, and renaming files between different folders and sharing with other people means that Dropbox offers users control over fundamental actions, allowing them to work in a personalized way, increasing their sense of ownership:

Making it a breeze for users to navigate no matter if they’re on a computer or a mobile device, Dropbox keeps things consistent in both: website and mobile app design:

To prevent errors from happening, Dropbox has implemented an interesting feature. If a user attempts to upload a file that’s too large, Dropbox triggers an error message. This message is quite helpful, as it guides the user to select a smaller file and clearly explains the issue. It’s a nifty feature that ensures users know exactly which steps to take next:

Dropbox cleverly employs affordances to ensure that users can easily figure out how to navigate the app. Take, for instance, the blue button located at the top of the screen — it’s your go-to for creating new files and folders. This is a familiar and intuitive pattern that users can quickly grasp:

Consider now flexibility and efficiency. On Dropbox, the user can access their files from any gadget, and they can keep working even when they are offline without worrying about losing anything. It makes staying productive a breeze, no matter where the users finds themselves:

Dropbox has a clean and minimalist design that’s a breeze to use and get around in. Plus, it’s available in different languages, ensuring accessibility for people all around the world:

Dropbox goes the extra mile by using additional methods alongside heuristic evaluation, demonstrating a high positive impact on their services. All this dedication to applying the best heuristics on their products has made Dropbox one of the most popular storage services globally.

Heuristic evaluation fits into the broader UX design process and can be conducted iteratively throughout the design lifecycle, despite being commonly used early in the design process.

It provides valuable insights to inform design decisions and improvements and enables UX designers to effectively identify and address usability issues.

Conclusion and key takeaways

In this article, we have seen that heuristic evaluation is a systematic and valuable approach to identifying usability problems in systems and products. Through the use of general usability guidelines, it is possible to highlight gaps in the user experience, addressing areas such as clarity, consistency and control. This evaluation is conducted by a multidisciplinary team, and the problems identified are recorded in detail, allowing for further prioritization and refinement.

Much like a complex puzzle, improving usability and user experience requires identifying patterns and providing instructive feedback when working collaboratively.

Checking interfaces using heuristic evaluation can uncover many issues, but it’s not a replacement for what you learn from watching actual users. Think of it as an extra tool to understand users better.

Remember that heuristic evaluation not only reveals challenges but also empowers you as a UX professional to create more intuitive and impactful solutions.

When you mix in heuristic evaluation while making your designs, you can end up with products and systems that are more helpful and user-friendly without spending too much. This helps make your products or services even better by following good user experience tips.

So don’t hesitate: make the most of the potential of heuristic evaluation to push usability to the next level in your UX project.

Undergraduate vs. Graduate: Educate Yourself On The Difference

• Undergraduate Meaning
• Undergraduate Student And Degree
• Graduate Meaning
• Graduate Degree And Student
• Graduate Origin
• Postgraduate Meaning

⚡ Quick summary

The main difference between undergraduate and graduate is that undergraduate is always used in the context of the first level of college or university education (the level where you can earn a bachelor’s degree ). In terms like graduate student and graduate degree , graduate refers to a level of advanced education beyond the undergraduate level, especially a master’s degree or doctorate . The noun graduate is more general, simply referring to a person who has completed a level of education (someone who has graduated ).

The difference between undergraduate and graduate is a difference of degrees (*throws graduation cap in the air to celebrate the pun*).

The level of education that each word involves varies depending on how the word is being used, and there are situations in which both words can be used in the same situation. For example, you can become a graduate student after graduating with an undergraduate degree.

The word graduate can mean very different things depending on whether it’s used as a noun (as in recent   high school graduates ), an adjective (as in graduate student and graduate degree ), or a verb (as in I plan to graduate next May ). The same goes for its shortened form, grad , which can be used as a noun (as in Congrats, grads! ) or an adjective (as in grad program ).

Undergraduate can also be used both as a noun (as in I’m an undergraduate at Stanford University ) or an adjective (as in I’m working toward my undergraduate degree ). It can be shortened to undergrad in both cases.

By the end of this article, you’ll have an advanced degree in all the different ways graduate, grad , undergraduate , and undergrad are used, and what they mean in each case.

What does undergraduate mean?

An undergraduate is “a student in a university or college who has not received a first, especially a bachelor’s, degree.” For example, a college student might say I’m an undergraduate at the University of Texas if they were pursuing a bachelor’s degree there.

Undergraduate is also commonly used as an adjective in this same context, in terms like undergraduate student , undergraduate degree , and undergraduate studies.

Undergraduate is often shortened to undergrad as both a noun and an adjective.

In undergraduate, the prefix under- is used to indicate a lower rank or status. The educational status of an undergraduate student is below that of a graduate student.

What’s the difference between wisdom and knowledge ? Here’s a lesson on the two terms.

What is an undergraduate student ? And what is an undergraduate degree ?

An undergraduate student is a student who is pursuing a degree at the first level of higher education (meaning the level after high school) at a college or university. Undergraduate students are typically those working to earn a bachelor’s degree (or, less commonly, an associate’s degree ). These degrees are often referred to with the general term undergraduate degree.

Outside of the US, an undergraduate degree is sometimes called a first degree. There are also other types of undergraduate degrees outside of the US, such as a foundation degree (which, like an associate’s degree, is typically a two-year degree).

What does graduate mean?

As a noun, the word graduate  [  graj -oo-it ] refers to “a person who has received a degree or diploma on completing a course of study.” In other words, a graduate is someone who has completed a particular level of schooling or an educational program—a child who just finished kindergarten and a doctor who just completed medical school are both graduates. It can even be used figuratively , as in She’s a graduate of the school of hard knocks.

As a verb, graduate [  graj -oo-eyt ] means “to receive a degree or diploma on completing a course of study.” The process of graduating—and the ceremony itself—is called graduation .

As an adjective, graduate [  graj -oo-it ] means something more specific. It’s used to indicate that a student, degree, or educational program is an advanced one, beyond the level of a bachelor’s degree. This sense of graduate is most commonly used in terms like graduate degree, graduate school , graduate program, and graduate student.

What is a graduate degree ? And what is a graduate student ?

Graduate degree typically refers to a degree beyond a bachelor’s, most commonly a master’s.

A graduate student is a student who’s pursuing an advanced degree after having earned their undergraduate degree (such as a bachelor’s degree) by graduating from an undergraduate program. Calling someone a graduate student most often means they are pursuing their master’s degree, but it may be another advanced degree, such as a PhD (You’d most commonly call such students PhD students. Or you might say they are working toward their doctorate or their doctoral degree.)

To earn a graduate degree, graduate students go to a division of a university known as graduate school , and such a program is often called a graduate program. In all of these terms, graduate is often shortened to grad : grad school , grad student , grad program . (A student doesn’t become a graduate student until they take graduate-level courses. For example, if a student graduates with a bachelor’s degree and then later pursues a different bachelor’s degree, they are still an undergraduate student .)

Some graduate studies are referred to in more specific ways: medical students go to medical school to earn their medical degree ; law students go to law school to earn their law degree.

Do you know the difference between these highly-esteemed graduate degrees and titles: PhD, MD, and Dr ?

Where does the word graduate come from?

Graduate comes from the Medieval Latin graduārī, meaning “to take a degree.” It ultimately derives from the Latin gradus, meaning “a step.” Each time you graduate, you take a step to the next level of education.

What does postgraduate mean?

The adjective postgraduate is sometimes used in the same way as the adjective sense of the word graduate, especially in the UK, as in postgraduate student or postgraduate studies.

Postgraduate should not be confused with postdoctoral , which refers to studies, research, or professional work above the level of a doctorate.

How to use undergraduate vs. graduate

The best way to sort out the different meanings of undergraduate and graduate is to determine whether each word is being used as a noun, an adjective, or a verb. Here’s an easy breakdown of the differences.

• undergraduate (noun): A college student pursuing a non-advanced degree, most commonly a bachelor’s degree. Can be shortened to undergrad.
• undergraduate (adjective): Used in the context of colleges and university programs ( undergraduate programs ) where students are pursuing a degree (generally referred to as an undergraduate degree ) that is not an advanced degree. Also sometimes shortened to undergrad.
• graduate (noun): A person who has completed a particular level of schooling or educational program. Can be shortened to grad.
• graduate (verb): To complete a level of schooling (and, typically, to receive a degree or diploma). You can graduate from kindergarten, high school, college, graduate school, medical school, etc.
• graduate (adjective): Used in the context of advanced schooling—a level beyond a bachelor’s degree, most commonly a master’s program. Used in terms like graduate student , graduate school , graduate degree , graduate program , graduate courses , etc. Often shortened to grad.

Examples of undergraduate, undergrad, graduate, and grad used in a sentence

Let’s look at some examples of these words in actual, real-life use to get the meanings straight.

• As an undergraduate, she had studied engineering; as a graduate student, she switched to architecture.
• I completed my undergraduate degree after five years and a lot of hard work.
• As a graduate student, you will be expected to complete a thesis.
• You should start thinking about graduate school applications before you graduate.
• Most of the applicants for this position are recent college graduates.

What is omnichannel marketing?

Picture this: you’re browsing online for some new work clothes, and you add something to your virtual cart but ultimately decide not to buy it. Then later, you see an ad on social media for the abandoned garment. Some scratch their heads at this, but it’s actually an example of omnichannel marketing.

The prefix “omni” means “all,” and “channel” is a reference to the many ways customers might interact with a company—in physical stores, by surfing the web, on social media, and in emails, apps, SMS, and other digital spaces. And this omnichannel approach can be a powerful way to meet your customers where they are, providing them good service in line with their preferences and needs. (Note that, in this article, we use the terms “customers,” “consumers,” and “shoppers” interchangeably in referring to omnichannel marketing in both B2B and B2C contexts.)

More and more, customers move across all channels—in person, online, and beyond—to get what they want. But not every customer is looking for the same thing, and omnichannel marketing acknowledges that. Some people want more services for certain transactions; others prefer low-touch, 24/7 interactions. Effective omnichannel marketing , then, happens when companies provide a set of seamlessly integrated channels, catering to customer preferences, and steer them to the most efficient solutions.

So why is omnichannel marketing important? Research on the omnichannel experience  shows more than half of B2C customers engage with three to five channels each time they make a purchase or resolve a request. And the average customer looking to make a single reservation for accommodations (like a hotel room) online switched nearly six times between websites and mobile channels. If these customers encounter inconsistent information or can’t get what they need, they may lose interest in a brand’s products or services.

And this can translate into business outcomes. Omnichannel customers shop 1.7 times more than shoppers who use a single channel. They also spend more.

Sometimes the term omnichannel is used in the context of customer service or customer experience . And it’s also used as a descriptor of other elements that go into supporting an organization’s omnichannel efforts—for instance, omnichannel supply chains , which is shorthand for an approach in which companies ensure that their supply chains are optimally set up to support omnichannel marketing efforts.

What are examples of omnichannel?

Omnichannel approaches are commonly used in retail  (both B2B  and B2C ), but you’ll also find it in healthcare and other spaces. Medtech companies , for instance, use a variety of channels including digital marketing, inside sales, portal and e-commerce, and hybrid sales-rep interactions to engage with healthcare professionals.

Several omnichannel examples  can illustrate various approaches:

• Best Buy typically focuses on commerce (both in store and online), but boosted its in-store experience by creating offerings for customers to explore smart home-technology solutions, pairing them with free in-home advisory services. And its mobile app lets customers “scan to shop” from catalogs and curbside, or buy online and pick up merchandise in the store itself, smoothing the end-to-end journey for customers with the 24/7 tech support from its Geek Squad. Best Buy’s Totaltech support offer was compelling to customers—it launched with 200,000 memberships in 2018, which climbed to two million within a year.
• Beauty retailer Sephora emphasizes omnichannel personalization, relying on rich in-app messaging, personalized push notifications, and easy ways for customers to book in-person consultations. Its in-store technology is a powerful complement that allows employees to access customer favorites and suggest products they might try next. Its loyalty program also plays an important role. The efforts are already driving value for Sephora: data showed that customers visiting the retail website within 24 hours of visiting a store were three times more likely to make a purchase, and orders were 13 percent higher than for other customers.
• Nike takes an ecosystems view of omnichannel, extending the brand experience and offering customers an ever-growing platform of content, offers, and community interactions. Its SNKRS and Run Club apps, for example, facilitate in-person meetups, running groups, and events. It also has an app for delivering individual workouts and fitness programs, creating experiences that go far beyond shoe and apparel lines to meet customers in their day-to-day routines.

How has omnichannel been affected by the COVID-19 pandemic?

Omnichannel rose during the COVID-19 pandemic as more consumers turned to e-commerce. Due to the increased demand for contactless shopping during the height of the pandemic, US grocery stores saw 20 to 30 percent of their business shift to online . Before the pandemic, e-commerce accounted for just 3 to 4 percent of total sales for grocers.

The shifts made during the pandemic are likely to persist . In the pandemic, people gravitated to curbside pickup, “buy online, pay in store” models, and self-checkout at higher rates than in the past. And recent research indicates these behaviors are “sticky”—indeed, about 70 percent of people who first tried self-checkout in the pandemic say they’ll use it again.

Introducing McKinsey Explainers : Direct answers to complex questions

What do customers want out of the omnichannel experience.

Customers want a compelling and personalized omnichannel user experience with robust digital capabilities, both online and offline. About 60 to 70 percent of consumers research and shop both in stores and online . More concretely, over one-third of Americans  made omnichannel features—think buying online and picking up in store or curbside—part of their regular shopping routines since the COVID-19 pandemic emerged. Nearly two-thirds of those individuals plan to continue doing so. And younger buyers, like Gen Zers, embrace omnichannel enthusiastically; these customers don’t think in terms of traditional channel boundaries, and they expect brands and retailers to provide a seamless experience, no matter where they are.

In a sense, all customers are omnichannel customers now, McKinsey partner Tiffany Burns  explains in an episode of the McKinsey on Consumer and Retail podcast :

“Many retailers still think, ‘There are omnichannel interactions and store interactions, and I’m optimizing those two things separately. I have two different teams working on and thinking about those experiences.’ But as a consumer, when I go on the retailer’s website or app, I expect to see availability, a connection to what’s in the store, and a way to order things that I can pick up in store. I also expect to be able to stand in the aisle in the store and research a product. Today, consumers are figuring out workarounds to do all those things: they’re switching over from the app to Google, looking up the product, and searching for reviews.”

Organizations that make shopping a seamless omnichannel experience , or provide an app that helps customers find their way or see what’s in stock in the store, are already creating experiences that are a win for omnichannel customers .

Is omnichannel the same thing as phygital? And what is phygital, anyway?

Omnichannel is a business strategy, while “phygital” (a portmanteau that combines the word “physical” and “digital”) refers to the integration of the physical and digital worlds.

The term suggests a completely connected world that is both physical and digital at the same time . While fewer consumers are visiting brick-and-mortar stores and choosing to use e-commerce instead, more than 80 percent of retail sales still occur in a physical location . By 2030, the shopping experience will be highly personalized , and some activities may even take place in the metaverse . According to a recent survey, 80 percent of US adults  want personalization from retailers with multiple, personalized touchpoints , which can include a mobile app, digital displays, interactive screens, tech-enabled associates, and point of sale.

What about omnichannel vs multichannel?

When it comes to omnichannel vs multichannel, the key difference is the focus at the center of all efforts. Omnichannel is a customer-centric approach in which all channels are integrated so the customer has a unified and consistent experience whether they are at a physical store, using an app, or on a website. Multichannel, in contrast, tends to revolve around products instead of customers. It aims to inform as many people as possible about the product or brand, and the channels are not linked, so the customer experience is often different for each channel.

An interview with an insurance executive, Eric Gewirtzman of BOLT , makes that distinction relatable: “Insurance customers are already moving between various channels,” Gewirtzman says. “But there’s a big difference between being multichannel and being omnichannel. Just because carriers have, say, an exclusive agent channel, an independent agent channel, and a website, doesn’t mean they’re omnichannel. Too often, consumers will get a different experience and different results depending on which channel they use. This has to change. If there is no awareness between the channels, sales are lost.”

What is omnichannel personalization?

Omnichannel personalization refers to the way organizations might tailor the customer experience for individuals across physical and digital channels. This includes multiple touchpoints that cater to the customer’s preferences pre-visit, during the visit, and post-visit. Customers receive products, offers, and communications that are unique to them as individuals.

Efforts to personalize the omnichannel market can have a big payoff. Indeed, getting omnichannel personalization right  could help companies increase revenue by 5 to 15 percent across the full customer base.

While companies recognize the power of omnichannel personalization, they may face roadblocks in implementing these efforts for a variety of reasons:

• Omnichannel personalization requires a lot of investment in technology  (both software and hardware). Personalizing physical spaces often starts from scratch because it requires enabling digital touchpoints such as screens, kiosks, or tablets for store associates, which may not exist.
• It is difficult to deliver a seamless customer experience and train employees. The front line needs training to understand and reinforce the customer journey.
• Traditionally, companies operate their digital and physical channels independently. Omnichannel personalization requires companies to rethink their organizational structure across both the digital and physical parts of the business .

These barriers, however, can be overcome. Five steps can help companies achieve omnichannel personalization :

• Define the omnichannel personalization strategy and learning agenda. It’s crucial to develop a clear view on key moments of influence in the customer journey , and then identify what outcomes are desired at each step of that journey. Finally, an organization needs to prioritize use cases to test, looking at their ability to deliver business benefits and value to customers.
• Address five digital touchpoints to activate personalized experiences in physical environments. Companies need to connect digital and physical footprints to drive omnichannel personalization, especially at touchpoints where these worlds converge. Five are particularly important: mobile apps, digital displays, interactive screens, tech-enabled associates, and point of sale.
• Use an omnichannel “ decisioning engine ” to deliver experiences and measure performance. This can help organizations identify, quickly and accurately, the next best action to take with each customer.
• Implement agile operating practices. Personalized marketing goes beyond mere technology; it requires new ways of working, and agile marketing teams  can help in this regard.
• Activate omnichannel personalization in the field. To bring all these elements together, a company’s sales force must be fully aligned and well trained. In-person teams could make your customer’s day, so frontline personnel need to support personalization efforts, understand their value, and use digital tools to deliver the complete experience.

What is omnichannel strategy?

An omnichannel strategy for marketing is a way of ensuring that your efforts drive tangible business value. Rather than rushing blindly into the space, or haphazardly approaching it, organizations should step back and think about underlying business value drivers. Excelling in omnichannel depends on a laser focus on value creation, looking at both strategic and customer priorities to craft the omnichannel strategy that will be most effective for their unique circumstances.

The most successful companies set their omnichannel strategy by leading with their strategic ambition and aspirations for customer experience. There are three primary omnichannel strategies :

• Commerce. This prioritizes cross-channel shopping experience both in store and online.
• Personalization. This strategy focuses on tailored, targeted, and relevant cross-channel engagement at scale.
• Ecosystem. Here, the strategy aims to provide rich cross-channel platforms integrated with consumer needs and lifestyles.

What’s involved in omnichannel operations?

Organizations can build leading omnichannel operations , spanning a variety of areas. By strengthening the foundation of your omnichannel operations and focusing on strategy, structure, and processes, you could gain a performance edge.

Topics to explore include mastering omnichannel supply chains , creating a customer-centric supply chain strategy , designing the omnichannel distribution network of the future , reimagining the role of physical stores , and more.

What should I know about B2B omnichannel?

Omnichannel has become a permanent part of B2B sales , with e-commerce, face-to-face, and remote videoconference sales all a necessary part of buyers’ experience. According to a 2021 McKinsey survey of US-based B2B decision makers, 94 percent of respondents view today’s B2B omnichannel reality  as being as effective or more effective than before COVID-19. The findings also revealed that B2B customers regularly use ten or more channels to interact with suppliers, up from five in 2016.

B2B omnichannel efforts can be a path to grow an organization’s market share, but loyalty is up for grabs, with customers more willing than ever to switch suppliers for a better omnichannel experience. B2B decision makers use more channels than ever before to interact with suppliers, and being attuned to those channels will be important.

There are five must-dos for B2B companies seeking to retain customer loyalty and succeed in omnichannel:

• offer a performance guarantee (nearly 80 percent of B2B customers say it’s crucial)
• show product availability online
• enable purchases over any channel
• provide customer service in real time
• ensure the customer experience is consistent as buyers toggle between channels

While B2C omnichannel efforts might be the first to spring to mind, omnichannel experience is crucial to giving all customers a better and more seamless journey.

What Is a Full-Stack Developer? A Guide to Full-Stack Development

If you’re bored in your current development role, transitioning into a full-stack development job might be the best thing you could do for your career.

According to LinkedIn’s 2020 Emerging Jobs Report, full-stack developer jobs are in 4th place on the list of growing jobs. Research from the U.S. Bureau of Labor Statistics (BLS) shows a similar trajectory, as they estimate that web development and design jobs will increase by 8%  by 2029.

But what is a full-stack developer, what do they do, and how do you become one? Read on, and we’ll tell you everything you need to know about being a full-stack developer.

Let’s dive in!

What Does “Full-Stack” Mean?

Before becoming a full-stack developer, you need to understand the term “full-stack.” Developers working in a “full-stack” capacity work on both frontend and backend development projects.

Frontend development (or client-side development) projects include anything that users see. It includes websites and web applications that customers interact with (like the interface of an ecommerce web application).

Backend development (or server-side development) projects include any behind-the-scenes part of a website or web app. Specifically, backend development focuses on three things:

• The server:  The computer that runs the backend of the website
• The database:  The space where the website stores its data
• Application:  The tool that communicates with the server and database

As full-stack developers work on both frontend and backend projects, they need to use both frontend and backend programming languages  and tools in their work.

That includes languages like HTML , JavaScript , and CSS for frontend development and programming languages like Java, Python , and Ruby for backend development.

But aside from coding, what do full-stack developers do on a day-to-day basis?

What Does a Full-Stack Developer Do?

The everyday responsibilities you can expect as a full-stack developer will differ based on the company you work for, your industry, and your expertise. All these factors will influence the sort of work your employer gives you.

However, if you look at job postings for full-stack developers, you’ll notice that many positions share ten typical responsibilities. These include:

• Designing the architecture of new websites and web-based programs.
• Developing application programming interfaces (APIs). APIs are software intermediaries that help applications communicate with each other.
• Working with users to understand their technology needs when designing new websites or programs.
• Developing updates to enhance the usability and capabilities of the backend of a website.
• Maintaining the frontend of a website to make sure it works.
• Optimizing websites to make sure they’re mobile-friendly.
• Working with graphic designers to develop attractive and functional websites.
• Creating servers and databases for websites.
• Overseeing a project through each phase of the systems development life cycle (SDLC).
• Working with other professionals (including DevOps engineers , cybersecurity experts, graphic designers, and other web developers).

Naturally, as full-stack developers have an extensive range of responsibilities at work, they’re compensated reasonably well.

Let’s cover the average full-stack developer salary next.

How Much Do Full-Stack Developers Make?

Let’s look at some data for full-time positions in the U.S. specifically.

According to Glassdoor, the average full-stack developer earns $98,000 annually, and most developers earn between $63,000–$156,000 . Glassdoor’s average salary figure is based on reports from 3,372 salaries.

According to Payscale, the average base salary of a full-stack developer is $75,057, and many developers earn between $48,000–$113,000  annually.

According to Indeed, the average full-stack developer earns $104,396 annually . Their data is based on reports from 5,000 salaries.

Finally, according to Talent.com, the median full-stack development salary is $107,434, and the range is between $87,750–$144,754 annually. Talent.com’s average salary figure is based on 10,000 salaries.

There’s an extensive range of average salaries between these websites.

This deviation is due to several factors, including education, experience, job responsibilities, the company (and its profitability), the location of the job, and whether the position includes benefits.

So, how does the salary of a full-stack developer compare to other jobs?

According to our calculations, the average full-time WordPress developer salary in the U.S. is $63,348, the average web developer earns between $60,000–$75,000 , and the average PHP developer earns $63,000 (in a junior role) and $94,000 (in a senior position) .

That means that full-stack developers earn more — however, full-stack developers need to master a broader range of tools and technologies than other developers.

Let’s cover some of those tools now.

What Skills Do You Need to Become a Full-Stack Developer?

If you want to become a successful full-stack developer, there are ten frontend and backend development skills and abilities that you should build. These include:

1. The Ability to Code in Frontend Languages

As full-stack developers frequently work on the frontend of websites, you’ll need to master frontend development languages like:

Developers use Hypertext Markup Language (HTML) to create the structure of websites. You’ll use HTML when you create web pages with distinct headings, tables, lists, paragraph boxes, and images.

Developers use Cascading Style Sheets (CSS) to create the stylistic parts of the website’s user interface.

As a full-stack developer, you’ll use CSS to add stylistic elements (like colors and fonts) and adjust the website for mobile and tablet devices.

Developers use Javascript to create the elements of a webpage that interacts with a user.

As a full-stack developer, you’ll use Javascript to build the functional parts and draw together elements from the frontend and backend.

For example, you might use Javascript when creating buttons for users to click.

2. Expertise in Frontend Frameworks and Libraries

During frontend development projects, full-stack developers use a range of frameworks and tools to work quickly. Naturally, it would help if you learned some of these frameworks and tools, including:

Bootstrap is an extensive code framework that offers HTML, CSS, and Javascript code. Bootstrap is currently the world’s most popular frontend framework, so it’s an excellent tool for your arsenal.

jQuery and React

jQuery and React are both frameworks that developers use for JavaScript projects.

Angular is a platform and framework developers use to build websites and web-based applications. Angular is a very new tool, as Google’s Angular team only released it in 2016.

Angular is an excellent choice for developers who need to design a website or web app that works consistently across computers, phones, and tablets.

3. The Ability to Code in Backend Languages

As full-stack developers also work with the backend of websites, you’ll need to master backend development languages like:

Hypertext Preprocessor (PHP) is an all-purpose scripting language used for web development.

PHP was first released in 1995 and has been reasonably popular ever since, as 79.1%  of all websites with known languages use it. People often compare PHP to Angular  (though Angular is for frontend development).

Python is a programming language that dates back to 1991. Python is particularly useful when working with databases or building a web app.

Java is an object-oriented programming (OOP) language based around objects. It was first released in 1995, and 40.2%  of software developers now use it.

Ruby is another all-purpose programming language that full-stack developers use. Ruby is an open-source language that’s very easy to pick up. 5% of all websites with a known server-side programming language use Ruby.

4. Expertise in Backend Frameworks and Libraries

Like with frontend development, full-stack developers use a range of frameworks and tools to work on backend projects quickly.

Naturally, you’ll need to learn some of these tools and frameworks, including:

The Laravel Framework

The Laravel framework is a PHP framework that gives developers access to an extensive library of pre-written code. The Laravel framework is open-source and follows the MVC architectural pattern (MVC stands for “Model, View, Controller”).

Spring is an open-source framework that developers use to build projects with Java quickly.

Spring uses aspect-oriented programming (AOP). AOP is a programming paradigm that uses cross-cutting to create a flexible program that adjusts to changes quickly.

Django is a scalable, secure, and fast framework developers use to build projects with Python. Django is perfect for website-building, as it can help you create any website and works with most client-side frameworks.

5. Database Skills

During backend development projects, full-stack developers need to build and manage databases. Naturally, you’ll need to learn to use some of the most popular database tools, including:

MySQL is a free and open-source database system developers use to store web databases.

It’s a relational database management system that orders data into tables. MySQL is also part of the LAMP software stack (which we’ll cover in the next section).

Oracle is a database management system popular for large projects and complicated databases. Oracle also uses a relational database approach, though Oracle designed its system to function specifically with complex databases.

If you want to get the most from MySQL and Oracle, you’ll also need to learn to use structured query language (SQL). SQL will help you communicate with the tools to update and retrieve data quickly.

MongoDB is a database tool developers use for web apps. Unlike Oracle and MySQL, MongoDB doesn’t use SQL, so you won’t need to learn how to use SQL to use MongoDB.

6. Expertise in Popular Stacks

As a full-stack developer, you’ll need to learn to use popular tech stacks.

A tech stack is a collection of software used to produce web applications, projects, and websites. While the stacks you use will depend on your employer and team, you should familiarize yourself with popular stacks before becoming a full-stack developer.

Some of these popular stacks include:

• The LAMP stack :  Includes Linux, Apache, MySQL, and PHP
• The MEAN stack : Includes MongoDB, Express.js , Angular.js, and Node.js
• The MERN stack:  Includes MongoDB, Express.js, React.js, and Node.js
• The SERN stack : Includes SQL, Express.js, React.js, and Node.js
• The Django stack:  Includes Django, Python, and MySQL
• The Ruby on Rails stack:  Includes Ruby, SQLite, and Rails

7. An Understanding of DevOps

Depending on your organization, you may need to work with DevOps engineers in your full-stack developer role. DevOps engineers apply a combination of tools, practices, and ideas to projects to help them move from concept to release quickly.

Naturally, you should understand the DevOps framework if you need to take a DevOps approach.

The DevOps approach uses a modified version of the SDLC that guides developers through building and releasing updates and projects incrementally (DevOps engineers refer to this as “Continuous Integration/Continuous Delivery” or CI/CD).

Once you understand what DevOps is, you’ll want to learn how to get the most from the approach. That means mastering tools like:

• Atlassian Bamboo and Jenkins,  which automate repetitive tasks
• Puppet and Chef, which help DevOps engineers configure different elements of systems so that they’re consistent
• Nagios and Raygun, which allow developers to track a project’s performance after deployment
• Docker and Kubernetes,  which help developers package code and deploy it in containers

8. An Understanding of UX Design Principles

As full-stack developers build many websites, you’ll need to learn how to design a great website using User Experience (UX) Design principles. These principles include:

• Focus on the user
• Use consistency
• Structure your website with hierarchy (i.e., put the essential elements first)
• Design your website for mobile and desktop devices
• Give the user control over their experience on the website
• Make your website accessible for all users (i.e., make sure people who are blind, deaf, and colorblind can interact with your website)
• Test the usability of your website before you release it

9. Experience With Developer Tools

If you have a development background, you may already know how to use essential developer tools like BitBucket, GitHub, and Git. However, as you’ll do a lot of web development as a full-stack developer, you should also learn to use web development tools  like:

• Invision Studio

You may also need to learn how to use WordPress development tools like DevKinsta . DevKinsta is a free suite of tools that will help you build, develop, and test WordPress websites.

Over 10,000 professionals currently use DevKinsta, including web designers, freelancers, and developers.

10. Great Soft Skills

Finally, any developer needs fantastic soft skills. While full-stack development is a technical job, you need to work with colleagues and users to deliver each project.

Naturally, you will need:

• Excellent active listening skills: To help you understand other people’s perspectives
• Excellent teamwork skills:  To help you work with others
• The ability to take constructive feedback: You’ll need to adjust your work based on feedback from colleagues and users
• The ability to mentor other developers:  Your employer may expect you to lend your expertise to junior developers who are still building their skills
• Time management skills:  You may need to juggle multiple projects simultaneously

So, assuming you have all of 10 of the skills we’ve discussed, why should you apply them to full-stack development?

Why Become a Full-Stack Developer?

As most full-stack developers earn $75,000+ a year, full-stack development is a lucrative career. But it also offers other benefits.

As a full-stack developer, you’ll bridge the disconnect between frontend and backend development. That will give you a unique approach to web development, as you’ll work on every aspect of a project (rather than just a tiny part).

Many developers find this part of the role gratifying as you take a project from concept to release.

Full-stack development is also an excellent career for professionals who like flexing different muscles at work. Full-stack developers use numerous tools and skills and work on a diverse range of projects — meaning your work will be highly engaging.

As you’ll learn many skills as a full-stack developer, you’ll also become a great asset to your employer. Naturally, if you’re interested in progressing into a management role, full-stack development could be the perfect stepping stone (depending on your company).

So, how do you start down the full-stack path?

How to Become a Full-Stack Developer

As you’ll need strong software development skills to succeed in a full-stack developer role, most full-stack developers transition into the position after working in another software development job.

If you haven’t worked as a developer before, you may want to consider pursuing a web developer, java developer , software engineer, frontend developer , or backend developer job first.

Once you have some experience, you can transition into a full-stack role with these steps:

Step 1: Master the Basics

First, you’ll need to improve your programming skills. Although you don’t need to be an expert in every language, we recommend improving your skills in:

There are many resources you can use to build your development skills. For example, you could use resources like The Odin Project , which will teach you the basics of full-stack development and how to develop with Ruby on Rails and Javascript.

As WordPress now powers 40%  of all websites on the internet, you should also learn how to use WordPress to manage a website, develop a theme, and use plugins.

Although you could learn through trial-and-error, the best way to learn WordPress is through an online course.

If you haven’t used PHP before, you should familiarize yourself with it as you learn WordPress.

As WordPress is primarily built on PHP, you may need PHP for backend development. Taking a course is a great way to learn PHP . You can also  install PHP , and build your skills over time.

Step 2: Enhance Your Knowledge

Once you’ve mastered the basics, you should prepare for your new full-stack development role by enhancing your knowledge and building your skills. There are many ways to do this, including:

• Identifying gaps in your knowledge and filling them through practice or tutorials
• Asking a full-stack developer at your workplace to mentor you and give you feedback on your preparedness for the job
• Upskilling through a coding boot camp or online certification, like LinkedIn’s Full-Stack Web Developer Learning Course or IBM’s Full-Stack Cloud Developer Professional Certificate .

You should also join the online full-stack development community through websites like StackOverFlow and subreddits like r/fullstack. Joining the community will help you learn by watching others, as you can see how they solve problems.

Step 3: Create a Portfolio and Apply For Jobs

Next, you should build a digital portfolio to show your full-stack development skills. Ideally, your portfolio should document two to four of your web development projects.

The best portfolios are pretty straightforward, as they include:

• A link to each website or project
• A detailed explanation of the tools and processes you used for each project
• Any reflections you have on the process (i.e., what worked well, any challenges you faced, what you learned from it)

Once you’ve finished your portfolio, add it to your resume and start applying for full-stack jobs. You can find full-stack positions on websites like:
