When to Write Scope of the Research

Here is a guide on When to Write the Scope of the Research:

• Before starting your research project, it’s important to clearly define the scope of your study. This will help you stay focused on your research question and avoid getting sidetracked by irrelevant information.
• The scope of the research should be determined by the research question or problem statement. It should outline what you intend to investigate and what you will not be investigating.
• The scope should also take into consideration any limitations of the study, such as time, resources, or access to data. This will help you realistically plan and execute your research.
• Writing the scope of the research early in the research process can also help you refine your research question and identify any gaps in the existing literature that your study can address.
• It’s important to revisit the scope of the research throughout the research process to ensure that you stay on track and make any necessary adjustments.
• The scope of the research should be clearly communicated in the research proposal or study protocol to ensure that all stakeholders are aware of the research objectives and limitations.
• The scope of the research should also be reflected in the research design, methods, and analysis plan. This will ensure that the research is conducted in a systematic and rigorous manner that is aligned with the research objectives.
• The scope of the research should be written in a clear and concise manner, using language that is accessible to all stakeholders, including those who may not be familiar with the research topic or methodology.
• When writing the scope of the research, it’s important to be transparent about any assumptions or biases that may influence the research findings. This will help ensure that the research is conducted in an ethical and responsible manner.
• The scope of the research should be reviewed and approved by the research supervisor, committee members, or other relevant stakeholders. This will ensure that the research is feasible, relevant, and contributes to the field of study.
• Finally, the scope of the research should be clearly stated in the research report or dissertation to provide context for the research findings and conclusions. This will help readers understand the significance of the research and its contribution to the field of study.

Scope and Delimitations in Research

Delimitations are the boundaries that the researcher sets in a research study, deciding what to include and what to exclude. They help to narrow down the study and make it more manageable and relevant to the research goal.

Updated on October 19, 2022

All scientific research has boundaries, whether or not the authors clearly explain them. Your study's scope and delimitations are the sections where you define the broader parameters and boundaries of your research.

The scope details what your study will explore, such as the target population, extent, or study duration. Delimitations are factors and variables not included in the study.

Scope and delimitations are not methodological shortcomings; they're always under your control. Discussing these is essential because doing so shows that your project is manageable and scientifically sound.

This article covers:

• What's meant by “scope” and “delimitations”
• Why these are integral components of every study
• How and where to actually write about scope and delimitations in your manuscript
• Examples of scope and delimitations from published studies

What is the scope in a research paper?

Simply put, the scope is the domain of your research. It describes the extent to which the research question will be explored in your study.

Articulating your study's scope early on helps you make your research question focused and realistic.

It also helps decide what data you need to collect (and, therefore, what data collection tools you need to design). Getting this right is vital for both academic articles and funding applications.

What are delimitations in a research paper?

Delimitations are those factors or aspects of the research area that you'll exclude from your research. The scope and delimitations of the study are intimately linked.

Essentially, delimitations form a more detailed and narrowed-down formulation of the scope in terms of exclusion. The delimitations explain what was (intentionally) not considered within the given piece of research.

Scope and delimitations examples

Use the following examples provided by our expert PhD editors as a reference when coming up with your own scope and delimitations.

Scope example

Your research question is, “What is the impact of bullying on the mental health of adolescents?” This topic, on its own, doesn't say much about what's being investigated.

The scope, for example, could encompass:

• Variables: “bullying” (dependent variable), “mental health” (independent variable), and ways of defining or measuring them
• Bullying type: Both face-to-face and cyberbullying
• Target population: Adolescents aged 12–17
• Geographical coverage: France or only one specific town in France

Delimitations example

Look back at the previous example.

Exploring the adverse effects of bullying on adolescents' mental health is a preliminary delimitation. This one was chosen from among many possible research questions (e.g., the impact of bullying on suicide rates, or children or adults).

Delimiting factors could include:

• Research design : Mixed-methods research, including thematic analysis of semi-structured interviews and statistical analysis of a survey
• Timeframe : Data collection to run for 3 months
• Population size : 100 survey participants; 15 interviewees
• Recruitment of participants : Quota sampling (aiming for specific portions of men, women, ethnic minority students etc.)

We can see that every choice you make in planning and conducting your research inevitably excludes other possible options.

What's the difference between limitations and delimitations?

Delimitations and limitations are entirely different, although they often get mixed up. These are the main differences:

This chart explains the difference between delimitations and limitations. Delimitations are the boundaries of the study while the limitations are the characteristics of the research design or methodology.

Delimitations encompass the elements outside of the boundaries you've set and depends on your decision of what yo include and exclude. On the flip side, limitations are the elements outside of your control, such as:

• limited financial resources
• unplanned work or expenses
• unexpected events (for example, the COVID-19 pandemic)
• time constraints
• lack of technology/instruments
• unavailable evidence or previous research on the topic

Delimitations involve narrowing your study to make it more manageable and relevant to what you're trying to prove. Limitations influence the validity and reliability of your research findings. Limitations are seen as potential weaknesses in your research.

Example of the differences

To clarify these differences, go back to the limitations of the earlier example.

Limitations could comprise:

• Sample size : Not large enough to provide generalizable conclusions.
• Sampling approach : Non-probability sampling has increased bias risk. For instance, the researchers might not manage to capture the experiences of ethnic minority students.
• Methodological pitfalls : Research participants from an urban area (Paris) are likely to be more advantaged than students in rural areas. A study exploring the latter's experiences will probably yield very different findings.

Where do you write the scope and delimitations, and why?

It can be surprisingly empowering to realize you're restricted when conducting scholarly research. But this realization also makes writing up your research easier to grasp and makes it easier to see its limits and the expectations placed on it. Properly revealing this information serves your field and the greater scientific community.

Openly (but briefly) acknowledge the scope and delimitations of your study early on. The Abstract and Introduction sections are good places to set the parameters of your paper.

Next, discuss the scope and delimitations in greater detail in the Methods section. You'll need to do this to justify your methodological approach and data collection instruments, as well as analyses

At this point, spell out why these delimitations were set. What alternative options did you consider? Why did you reject alternatives? What could your study not address?

Let's say you're gathering data that can be derived from different but related experiments. You must convince the reader that the one you selected best suits your research question.

Finally, a solid paper will return to the scope and delimitations in the Findings or Discussion section. Doing so helps readers contextualize and interpret findings because the study's scope and methods influence the results.

For instance, agricultural field experiments carried out under irrigated conditions yield different results from experiments carried out without irrigation.

Being transparent about the scope and any outstanding issues increases your research's credibility and objectivity. It helps other researchers replicate your study and advance scientific understanding of the same topic (e.g., by adopting a different approach).

How do you write the scope and delimitations?

Define the scope and delimitations of your study before collecting data. This is critical. This step should be part of your research project planning.

Answering the following questions will help you address your scope and delimitations clearly and convincingly.

• What are your study's aims and objectives?
• Why did you carry out the study?
• What was the exact topic under investigation?
• Which factors and variables were included? And state why specific variables were omitted from the research scope.
• Who or what did the study explore? What was the target population?
• What was the study's location (geographical area) or setting (e.g., laboratory)?
• What was the timeframe within which you collected your data ?
• Consider a study exploring the differences between identical twins who were raised together versus identical twins who weren't. The data collection might span 5, 10, or more years.
• A study exploring a new immigration policy will cover the period since the policy came into effect and the present moment.
• How was the research conducted (research design)?
• Experimental research, qualitative, quantitative, or mixed-methods research, literature review, etc.
• What data collection tools and analysis techniques were used? e.g., If you chose quantitative methods, which statistical analysis techniques and software did you use?
• What did you find?
• What did you conclude?

Useful vocabulary for scope and delimitations

When explaining both the scope and delimitations, it's important to use the proper language to clearly state each.

For the scope , use the following language:

• This study focuses on/considers/investigates/covers the following:
• This study aims to . . . / Here, we aim to show . . . / In this study, we . . .
• The overall objective of the research is . . . / Our objective is to . . .

When stating the delimitations, use the following language:

• This [ . . . ] will not be the focus, for it has been frequently and exhaustively discusses in earlier studies.
• To review the [ . . . ] is a task that lies outside the scope of this study.
• The following [ . . . ] has been excluded from this study . . .
• This study does not provide a complete literature review of [ . . . ]. Instead, it draws on selected pertinent studies [ . . . ]

Analysis of a published scope

In one example, Simione and Gnagnarella (2020) compared the psychological and behavioral impact of COVID-19 on Italy's health workers and general population.

Here's a breakdown of the study's scope into smaller chunks and discussion of what works and why.

Also notable is that this study's delimitations include references to:

• Recruitment of participants: Convenience sampling
• Demographic characteristics of study participants: Age, sex, etc.
• Measurements methods: E.g., the death anxiety scale of the Existential Concerns Questionnaire (ECQ; van Bruggen et al., 2017) etc.
• Data analysis tool: The statistical software R

Analysis of published scope and delimitations

Scope of the study : Johnsson et al. (2019) explored the effect of in-hospital physiotherapy on postoperative physical capacity, physical activity, and lung function in patients who underwent lung cancer surgery.

The delimitations narrowed down the scope as follows:

Scope and Delimitation – Definition and difference

Scope refers to the range of the research project and the study limitations set in place to define the boundaries of the project and delimitation refers to the specific aspects of the research project that the study will focus on.

In simpler words, scope is the breadth of your study, while delimitation is the depth of your study.

Scope and delimitation are both essential components of a research project, and they are often confused with one another. The scope defines the parameters of the study, while delimitation sets the boundaries within those parameters. The scope and delimitation of a study are usually established early on in the research process and guide the rest of the project.

Types of Scope and Delimitation

Significance of Scope and Delimitation

Setting limits and focusing your study through scope and delimitation is crucial for the following reasons:

• It allows researchers to define the research project’s boundaries, enabling them to focus on specific aspects of the project. This focus makes it easier to gather relevant data and avoid unnecessary information that might complicate the study’s results.
• Setting limits and focusing your study through scope and delimitation enables the researcher to stay within the parameters of the project’s resources.
• A well-defined scope and delimitation ensure that the research project can be completed within the available resources, such as time and budget, while still achieving the project’s objectives.

5 Steps to Setting Limits and Defining the Scope and Delimitation of Your Study

There are a few steps that you can take to set limits and focus your study.

1. Identify your research question or topic

The first step is to identify what you are interested in learning about. The research question should be specific, measurable, achievable, relevant, and time-bound (SMART). Once you have a research question or topic, you can start to narrow your focus.

2. Consider the key terms or concepts related to your topic

What are the important terms or concepts that you need to understand in order to answer your research question? Consider all available resources, such as time, budget, and data availability, when setting scope and delimitation.

The scope and delimitation should be established within the parameters of the available resources. Once you have identified the key terms or concepts, you can start to develop a glossary or list of definitions.

3. Consider the different perspectives on your topic

There are often different perspectives on any given topic. Get feedback on the proposed scope and delimitation. Advisors can provide guidance on the feasibility of the study and offer suggestions for improvement.

It is important to consider all of the different perspectives in order to get a well-rounded understanding of your topic.

4. Narrow your focus

Be specific and concise when setting scope and delimitation. The parameters of the study should be clearly defined to avoid ambiguity and ensure that the study is focused on relevant aspects of the research question.

This means deciding which aspects of your topic you will focus on and which aspects you will eliminate.

5. Develop the final research plan

Revisit and revise the scope and delimitation as needed. As the research project progresses, the scope and delimitation may need to be adjusted to ensure that the study remains focused on the research question and can produce useful results. This plan should include your research goals, methods, and timeline.

Examples of Scope and Delimitation

To better understand scope and delimitation, let us consider two examples of research questions and how scope and delimitation would apply to them.

Research question: What are the effects of social media on mental health?

Scope: The scope of the study will focus on the impact of social media on the mental health of young adults aged 18-24 in the United States.

Delimitation: The study will specifically examine the following aspects of social media: frequency of use, types of social media platforms used, and the impact of social media on self-esteem and body image.

Research question: What are the factors that influence employee job satisfaction in the healthcare industry?

Scope: The scope of the study will focus on employee job satisfaction in the healthcare industry in the United States.

Delimitation: The study will specifically examine the following factors that influence employee job satisfaction: salary, work-life balance, job security, and opportunities for career growth.

Setting limits and defining the scope and delimitation of a research study is essential to conducting effective research. By doing so, researchers can ensure that their study is focused, manageable, and feasible within the given time frame and resources. It can also help to identify areas that require further study, providing a foundation for future research.

So, the next time you embark on a research project, don’t forget to set clear limits and define the scope and delimitation of your study. It may seem like a tedious task, but it can ultimately lead to more meaningful and impactful research.

What Is Scope and Delimitation in Research?

The scope and delimitations of a thesis, dissertation or research paper define the topic and boundaries of the research problem to be investigated.

The scope details how in-depth your study is to explore the research question and the parameters in which it will operate in relation to the population and timeframe.

The delimitations of a study are the factors and variables not to be included in the investigation. In other words, they are the boundaries the researcher sets in terms of study duration, population size and type of participants, etc.

Difference Between Delimitations and Limitations

Delimitations refer to the boundaries of the research study, based on the researcher’s decision of what to include and what to exclude. They narrow your study to make it more manageable and relevant to what you are trying to prove.

Limitations relate to the validity and reliability of the study. They are characteristics of the research design or methodology that are out of your control but influence your research findings. Because of this, they determine the internal and external validity of your study and are considered potential weaknesses.

In other words, limitations are what the researcher cannot do (elements outside of their control) and delimitations are what the researcher will not do (elements outside of the boundaries they have set). Both are important because they help to put the research findings into context, and although they explain how the study is limited, they increase the credibility and validity of a research project.

Guidelines on How to Write a Scope

A good scope statement will answer the following six questions:

• Why – the general aims and objectives (purpose) of the research.
• What – the subject to be investigated, and the included variables.
• Where – the location or setting of the study, i.e. where the data will be gathered and to which entity the data will belong.
• When – the timeframe within which the data is to be collected.
• Who – the subject matter of the study and the population from which they will be selected. This population needs to be large enough to be able to make generalisations.
• How – how the research is to be conducted, including a description of the research design (e.g. whether it is experimental research, qualitative research or a case study), methodology, research tools and analysis techniques.

To make things as clear as possible, you should also state why specific variables were omitted from the research scope, and whether this was because it was a delimitation or a limitation. You should also explain why they could not be overcome with standard research methods backed up by scientific evidence.

How to Start Writing Your Study Scope

Use the below prompts as an effective way to start writing your scope:

• This study is to focus on…
• This study covers the…
• This study aims to…

Guidelines on How to Write Delimitations

Since the delimitation parameters are within the researcher’s control, readers need to know why they were set, what alternative options were available, and why these alternatives were rejected. For example, if you are collecting data that can be derived from three different but similar experiments, the reader needs to understand how and why you decided to select the one you have.

Your reasons should always be linked back to your research question, as all delimitations should result from trying to make your study more relevant to your scope. Therefore, the scope and delimitations are usually considered together when writing a paper.

How to Start Writing Your Study Delimitations

Use the below prompts as an effective way to start writing your study delimitations:

• This study does not cover…
• This study is limited to…
• The following has been excluded from this study…

Examples of Delimitation in Research

Examples of delimitations include:

• research objectives,
• research questions,
• research variables,
• target populations,
• statistical analysis techniques .

Examples of Limitations in Research

Examples of limitations include:

• Issues with sample and selection,
• Insufficient sample size, population traits or specific participants for statistical significance,
• Lack of previous research studies on the topic which has allowed for further analysis,
• Limitations in the technology/instruments used to collect your data,
• Limited financial resources and/or funding constraints.

Exploring Scope and Delimitation in Academic Research

Academic research is a meticulous process that requires precise planning and clear boundaries. Two pivotal components in this process are the scope and delimitations of the study. The definitions and establishment of these parameters are instrumental in ensuring that the research is effective, manageable, and yields relevant results.

The "scope" of a research project refers to the areas that the study will cover. It is the breadth and depth of the investigation. It defines the subject matter, the geographical location, the time frame, and the issues that the study will explore. Essentially, the scope delineates what the researcher aims to cover in the study.

On the other hand, "delimitations" are the boundaries or limitations set by the researcher. They define what the study will not include. Delimitations could involve the choice of research methodology , the selection of respondents, the duration of the study, and more. They help in confining the study to a manageable size while excluding peripheral elements.

Understanding and correctly implementing scope and delimitations are vital to ensuring your research is well-defined and focused, facilitating higher accuracy and relevancy in your findings.

Importance of scope in research

"Scope" in research refers to the comprehensive extent of study—it outlines the parameters of what will be explored and addressed. It defines the topic of the research , the geographical region under study, the timeframe considered, and the issues that the study will address. The scope of a research project is vital because it determines the depth and breadth of your investigation.

Defining the scope of research is a fundamental step in the research process for several reasons. First, it provides a roadmap for the study, giving the researcher clear guidelines about what to include and exclude. Without a well-defined scope, research can become unmanageably vast or lose its focus.

Second, the scope ensures the research's relevance and applicability. It helps the researcher maintain a tight focus on the study's central question , ensuring that all aspects of the research contribute to answering this question. This focus aids in avoiding irrelevant diversions that could dilute the final conclusions.

Finally, a well-defined scope can help ensure the efficient use of resources. Research involves considerable time, effort, and often financial resources. By providing clear boundaries, the scope ensures these resources are utilized effectively without wasted effort on peripheral issues.

Suppose a research study is looking at the impacts of social media usage on mental health. If the scope is too broad—like examining all social media platforms' effects on all demographic groups worldwide—then the research can quickly become unwieldy and hard to manage. It would involve vast amounts of data, requiring considerable time, resources, and computational power to analyze effectively.

However, if the scope is narrowed down—such as investigating the impact of Instagram usage on the mental health of teenagers in a specific city over the past five years—the research becomes far more manageable. This specific focus allows for a more in-depth analysis and likely will provide more meaningful, actionable results. This example illustrates the importance of appropriately defining the scope of research for its successful execution.

Determining the scope of your research

Setting the scope of your research project is a critical and delicate task. Below are steps, tips, and common mistakes to avoid when determining the scope of your research:

Steps to define the scope

• Identify Your Topic: The first step involves identifying and understanding your research topic. This knowledge will serve as a basis for determining the breadth and depth of your study.
• Define Your Research Questions: The research questions are the heart of your study. They will help you determine the specific areas your research should cover.
• Establish Boundaries: Clearly establish the geographical, temporal, and topical boundaries of your research. These boundaries will guide the range of your study.
• Choose Your Methodology: Decide on the research methods you will use as these will directly impact the scope of your study.

Tips for a manageable scope

• Stay Focused: Stay concentrated on your research questions. Do not stray into areas that aren't directly relevant.
• Be Realistic: Consider the resources (time, money, manpower) available. Ensure your scope is feasible given these resources.
• Seek Guidance: Consult with your academic advisor or peers for feedback on your proposed scope.

Common mistakes to avoid

• Overly Broad Scope: Avoid setting an overly broad scope which could result in an unmanageable and unfocused study.
• Too Narrow Scope: Conversely, a scope that is too narrow may miss important aspects of the research topic.
• Ignoring Resources: Not taking into account available resources when setting the scope can lead to a project that is impossible to complete.

Defining the scope of your research is a delicate balance, requiring careful consideration of your research questions, resources, and the depth and breadth of investigation needed to answer these questions effectively.

Importance of delimitations in research

In the context of academic research, "delimitations" refers to the choices made by the researcher which define the boundaries of the study. These are the variables that lead the researcher to narrow the scope of the study from its potential vastness to a manageable size.

Delimitations might include the geographic area where the study is confined, the participants involved in the study, the methodology used, the time period considered, or the specific incidents or aspects the study will focus on. Essentially, delimitations are the self-imposed limitations on the scope of the study.

Defining the delimitations of a research project is crucial for several reasons. Firstly, they establish the context or setting in which the study occurs. This, in turn, allows for the work to be reproduced in a similar context for verification or refutation in future studies.

Secondly, delimitations provide a way to narrow the scope of the research to a manageable size, thus avoiding the pitfall of an overly ambitious project. They help researchers to stay focused on the main research questions and prevent diversion into irrelevant aspects.

Finally, clearly defined delimitations enhance the credibility of the research. They offer transparency about the research design and methodology, which adds to the validity of the results.

For instance, in a research study examining the impact of technology on student achievement in a certain district, examples of delimitations might include focusing only on public schools, considering only high school students, and confining the study to a particular school year. These choices help to focus the research and ensure its manageability. Therefore, delimitations play a pivotal role in structuring and guiding an effective and efficient research study.

Setting delimitations for your research

Establishing appropriate delimitations for your research project is an important part of research design. Here are some steps, guidelines, and common mistakes to consider when setting your research delimitations:

Steps to establish delimitations

• Identify the boundaries: Begin by deciding the geographical region, time period, and subject matter your research will cover.
• Determine Your Research Population: Identify the specific population your study will focus on. This could be based on age, profession, geographical location, etc.
• Choose Your Research Methods: Decide the specific methods you will use to collect and analyze data, as these decisions will also set limitations on your study.

Guidelines for choosing delimitations

• Align with Your Research Objectives: The delimitations should be in line with your research questions and objectives. They should help focus your study without detracting from its goals.
• Be Practical: Consider the resources available, including time, funds, and access to data. Your delimitations should be feasible given these constraints.
• Seek Input: Consult with your research advisor or peers. Their feedback can help ensure your delimitations are appropriate and well thought out.

Common errors to avoid:

• Unrealistic Delimitations: Be wary of setting delimitations that are too stringent or ambitious to be feasible given your resources and timeframe.
• Undefined Delimitations: Avoid leaving your delimitations vague or undefined. This can lead to scope creep, where your project expands beyond its initial plan, making it unmanageable.
• Ignoring Delimitations: Once set, stick to your delimitations. Deviating from them can lead to a loss of focus and can compromise the integrity of your results.

Setting delimitations is a crucial step in research planning. Properly defined delimitations can make your research project more manageable, maintain your focus, and ensure the effective use of your resources.

The interplay between scope and delimitations

The relationship between scope and delimitations in academic research is a dynamic and interdependent one. Each aspect serves to shape and refine the other, ultimately leading to a focused, feasible, and effective research design.

The scope of a research project describes the breadth and depth of the investigation—what it aims to cover and how far it intends to delve into the subject matter. The delimitations, on the other hand, identify the boundaries and constraints of the study—what it will not cover.

As such, the scope and delimitations of a research study are intimately connected. When the scope of a study is broad, the delimitations must be carefully considered to ensure the project remains manageable and focused. Conversely, when the scope is narrow, the delimitations might be less constraining, but they still play a critical role in defining the specificity of the research.

Balancing the scope and delimitations is crucial for an efficient research design. Too broad a scope without carefully defined delimitations can lead to a study that is unwieldy and lacks depth. On the other hand, a very narrow scope with overly rigid delimitations might result in a study that overlooks important aspects of the research topic.

Thus, researchers must strive to maintain a balance—establishing a scope that is wide enough to fully explore the research topic, but also setting appropriate delimitations to ensure the study remains feasible and focused. In doing so, the research will be well-structured and yield meaningful, relevant findings.

Role of scope and delimitations in research validity

Scope and delimitations are fundamental aspects of research design that directly influence the validity, reliability, and replicability of a study.

Research validity refers to the degree to which a study accurately reflects or measures the concept that the researcher intends to investigate. A well-defined scope is critical to research validity because it clearly delineates what the study will cover. This clear definition ensures that the research focuses on relevant aspects of the topic and that the findings accurately reflect the concept under investigation.

Similarly, carefully thought-out delimitations contribute to research validity by identifying what the study will not cover. This clarity helps to prevent the study from straying into irrelevant areas, ensuring that the research stays focused and relevant.

In addition to contributing to research validity, scope and delimitations also influence the reliability and replicability of a study. Reliability refers to the consistency of a study's results, while replicability refers to the ability of other researchers to repeat the study and obtain similar results.

A clearly defined scope makes a study more reliable by providing a detailed outline of the areas covered by the research. This clarity makes it more likely that the study will produce consistent results. Moreover, clearly defined delimitations enhance the replicability of a study by providing explicit boundaries for the research, which makes it easier for other researchers to repeat the study in a similar context.

In summary, a well-defined scope and carefully thought-out delimitations contribute significantly to the validity, reliability, and replicability of academic research. They ensure that the research is focused, that the findings are relevant and accurate, and that the study can be reliably repeated by other researchers.

Examples of scope and delimitation in well-known research

• The Milgram Experiment: Stanley Milgram's famous psychology experiment sought to understand obedience to authority figures. The scope of this study was clearly defined—it focused on how far individuals would go in obeying an instruction if it involved harming another person. However, delimitations were set to ensure manageability. Participants were delimited to male individuals, and the experiment was confined to a controlled laboratory setting. These delimitations allowed Milgram to manage the research effectively while maintaining the depth of his study on human behavior.
• The Framingham Heart Study: This ongoing cardiovascular study began in 1948 and is aimed at identifying common factors that contribute to cardiovascular disease. The scope of the research is broad, covering many aspects of lifestyle, medical history, and physical characteristics. However, the study set clear delimitations: it initially only involved adult residents of Framingham, Massachusetts. This geographical delimitation made this broad-scope study manageable and eventually yielded influential results that shaped our understanding of heart disease.
• The Marshmallow Test: This well-known study by Walter Mischel explored delayed gratification in children. The scope was clearly defined: the study aimed to understand the ability of children to delay gratification and how it related to future success. The delimitations of the study included the age of the participants (preschool children), the setting (a controlled experiment with a treat), and the measure of future success (academic achievement, ability to cope with stress, etc.). These delimitations helped keep the study focused and manageable.

In all these examples, the researchers set a clear scope to outline the focus of their studies and used delimitations to restrict the boundaries. This balance between scope and delimitation was key in conducting successful and influential research.

In academic research, defining the scope and delimitations is a pivotal step in designing a robust and effective study. The scope outlines the breadth and depth of the investigation, offering a clear direction for the research. Meanwhile, delimitations set the boundaries of the study, ensuring that the research remains focused and manageable. Together, they play a crucial role in enhancing the validity, reliability, and replicability of a study.

Understanding the interplay between scope and delimitations is key to conducting efficient research. A well-defined scope paired with thoughtfully set delimitations contribute to a study's feasibility and its potential to yield meaningful and applicable results. Mistakes in setting the scope and delimitations can lead to unwieldy, unfocused research or a study that overlooks important aspects of a research question.

Reviewing famous studies, like the Milgram Experiment, the Framingham Heart Study, and the Marshmallow Test, we observe how a balanced approach to setting scope and delimitations can result in influential and valuable findings. Therefore, researchers should give careful thought to defining the scope and delimitations of their studies, keeping in mind their research questions, available resources, and the need for balance between breadth and focus. By doing so, they pave the way for successful and impactful research outcomes.

Defining Scope

Tips for identifying scope.

Once you decide on a research topic, you need to determine the scope of your topic.  The scope of a research topic is determined by how detailed you want your project to be.  This process will tell you if your topic is already too narrow or too broad.  Consider the following when determining the scope of your research topic (Leggett and Jackowski, 2012):

• What is my topic about?
• Can I define it clearly?
• What relationships does my topic have with other fields?
• Are there correlations, causes, and/or effects between my topic and other topics?
• If the amount of sources available is overwhelming, then your topic may be too broad.
• If there are limited sources on your topic, then it may be too narrow.
• Is there anything specific about the group, population, or objects that I am studying that make them stand out from the others?
• What have scholars already said about my topic and what have they concluded?
• Does the geographical location impact my topic in any way?
• The scope of a research topic depends on the page length requirements.  You might feel tempted to select a broader topic for a larger paper, but your paper will lack conciseness.

The following tips may help you identify the scope of your research topic (Center for Writing and Speaking, n.d.):

• Be flexible.  You may have to abandon ideas that do not necessarily fit with the topic you have.  Furthermore, you may need to focus your research on one of the main ideas you had for your topic, rather than all of them.
• You might be thinking "too big."  This is one of the main reasons why research topics are too broad.  This is especially true if you have to write a large paper (more than 5 pages).  The length may seem overwhelming, but choosing a big topic just to get the page length will make writing about the topic more difficult.
• Define the key terms in your topic.   What do you mean by each term?  This could help you identify a more specific subtopic that you may want to cover.  Use your definitions of the key words to formulate a narrower topic.
• Avoid vague or abstract key words in your topic, such as love, death, society, etc.   Are you referring to something specific within that term or category?  If not, then the topic is likely too broad.

The following web page from Agnes Scott College, titled "Narrowing Scope" may assist you in determining the scope of your research topic.

What Are The Main 10 Stages Of Research Process?

The research process typically involves several stages, each crucial for the successful completion of a study. Here are the main 10 stages of the research process:

• Identifying the Research Problem: This stage involves identifying a topic or issue that warrants investigation. Researchers should ensure the problem is significant, relevant, and feasible for study.
• Reviewing the Literature: Conducting a thorough review of existing literature on the chosen topic is essential. This helps researchers figure out what we already know, spot where there are holes in our knowledge, and make their research questions clearer.
• Formulating Research Questions or Hypotheses: Based on the identified research problem and literature review, researchers develop specific research questions or hypotheses that they aim to address through their study.
• Designing the Research Methodology: This stage involves selecting the appropriate research design, methods, and techniques for data collection and analysis. Researchers must consider factors such as the research objectives, the nature of the data, and ethical considerations.
• Sampling: Researchers need to determine the sampling strategy and select participants or samples that represent the population of interest. Sampling methods may vary depending on the research design and objectives.
• Data Collection: This stage involves collecting data using the chosen methods and techniques. Data collection may involve surveys, interviews, observations, experiments, or analysis of existing data, among other methods.
• Data Analysis: After collecting data, researchers look at it carefully using the right tools to figure out what it means. They want to find important ideas, check if their guesses are right, and answer the questions they’re studying.
• Interpreting Results: Researchers analyze the results of their data to understand how they relate to the questions or guesses they had at the beginning of their study. They assess the significance of the results, identify patterns or trends, and draw conclusions.
• Drawing Conclusions and Implications: Based on the interpretation of results, researchers draw conclusions regarding the research questions or hypotheses. They discuss the implications of their findings, their relevance to theory or practice, and any recommendations for future research or applications.
• Writing and Presenting the Research Report: Finally, researchers write a comprehensive research report detailing the entire research process, from problem identification to conclusions. The report typically includes an introduction, literature review, methodology, results, discussion, and conclusion. Researchers may also present their findings at conferences or publish them in academic journals.

Scope in Research

• Definition: The scope of research outlines the boundaries and extent of the study.
• Components: It includes various elements such as research objectives, questions, methodology, timeframe, and geographic coverage.
• Guiding Factor: Scope guides researchers in determining what aspects of the topic will be included in the study and what will be excluded.
• Clarity: Defining the scope ensures clarity and focus, preventing researchers from straying off-topic.
• Relevance: It helps in ensuring that the research addresses pertinent issues and contributes meaningfully to the existing body of knowledge.

Limitation in Research

• Definition: Limitations refer to constraints or weaknesses within the research study that may impact its validity or generalizability.
• Types: Limitations can arise due to various factors such as methodological constraints, resource limitations, scope constraints, ethical considerations, and time constraints.
• Acknowledgement: Researchers should openly acknowledge limitations to maintain transparency and credibility.
• Mitigation: While some limitations may be unavoidable, researchers can mitigate their impact through careful planning, rigorous methodology, and transparent reporting.
• Future Implications: Identifying and addressing limitations can provide valuable insights for future research, guiding researchers in overcoming similar challenges in subsequent studies.

What Is Scope And Limitation In Research Example?

Scope in research example.

Let’s consider a research study investigating the impact of social media usage on teenagers’ mental health in urban areas of a particular city over the past three years. The scope of this study would include:

• Research Goals: We want to understand how using social media affects how teenagers feel.
• Research Questions: How much do teenagers in cities use social media, and for how long? Does using social media relate to how teenagers feel, like if they feel sad or anxious?
• Research Methodology: Utilizing surveys and interviews to gather data on social media usage patterns and mental health indicators.
• Timeframe: The study will focus on data collected over the past three years to capture recent trends and changes.
• Geographic Coverage: The study will concentrate on urban areas within a specific city, ensuring relevance and context specificity.

Limitation in Research Example

In the same study, limitations may arise due to various factors:

• Methodological Limitation: The reliance on self-reported data from surveys and interviews may introduce response bias and inaccuracies.
• Resource Limitation: Limited funding and time constraints may restrict the sample size and the depth of data collection, potentially affecting the study’s comprehensiveness.
• Scope Limitation: Focusing solely on urban areas may limit the generalizability of the findings to rural or suburban populations.
• Ethical Limitation: Ensuring informed consent and protecting the privacy of participants may pose ethical challenges, especially when dealing with sensitive topics like mental health.
• Time Limitation: The study’s timeframe of three years may not capture long-term effects or trends in social media usage and mental health outcomes.

In this example, the scope defines the parameters and objectives of the study, while the limitations highlight potential constraints and challenges that may impact the research process and findings.

How Do You Write Scope And Limitations In Research?

Writing the scope and limitations section in a research paper involves clearly defining the parameters of your study and acknowledging any constraints or weaknesses that may impact its validity or generalizability. Here’s a step-by-step guide on how to write the scope and limitations in research:

• Begin with the Scope
• Start by defining the scope of your research. This involves outlining the boundaries and extent of your study.
• Clearly state the objectives of your research and the specific aspects you will investigate.
• Identify the research questions or hypotheses that you aim to address.
• Describe the methodology you will use, including data collection and analysis techniques.
• Specify the timeframe and geographic coverage of your study.

Scoping Study

Do you need a scoping study.

A scoping study is usually carried out before a full systematic review, to assess the breath of the research around the topic of interest. It may be used to determine how well the subject is researched and whether there is enough evidence or a real need to conduct a full systematic review. They are also planned to map keywords to relevant concepts and put the research topics in context. Scoping exercises are  not  mandatory and are only planned if there is a need to overview the state of the art for the topic of interest. 

In relevance to systematic reviews, they are widely used to:

• investigate the volume and state of available literature, 
• map concepts, keywords, and policies,
• to narrow down the scope of broad questions and make them suitable for the use of the SR methodology. 

The method of scoping research topics was first developed by the EPPI-Centre to pilot systematic reviews of environmental questions. They were then extended to clinical and social science topics and are gradually being adopted in other scientific disciplines.

How to conduct a scoping study

Scoping studies are descriptive and often not comprehensive, but they provide a roadmap of literature. They follow similar steps to a systematic review process to summarise the state of current research on a topic  without  the need for data extraction, quality assessment or sensitivity analysis. 

A standard framework proposed by Arksey, and O’Malley  [2] is commonly used in clinical and healthcare research. This framework can be adapted and applied in other fields as well.  

It consists of the following 5 steps:     Step 1: Identifying the research question,    Step 2: Identifying relevant studies,     Step 3: Study selection,     Step 4: Charting the data,     Step 5: Collating, summarising, and reporting results.

Identifying the research question : the objective of the review question and the purpose of the scoping study determine which aspects of the study are important and what details are needed to provide an appropriate description. For example, to assess different applications of an intervention, a map of relevant literature to find all subpopulation might be planned.

Identifying relevant studies : regardless of the topic, at least 2 key elements of the research question set the foundation for a scoping study: the population and the outcome of interest. But unlike systematic review questions scoping questions seek to describe important aspects of relevant research. For instance, an intervention question can be centered around “what kind” of interventions have been applied to a particular subject for an outcome of interest.

Study selection : the search strategies of scoping studies are often designed to capture a broader spectrum of literature. As a result, the study selection process often is done at two different levels to manage the volume. First, all irrelevant and out of focus literature are removed by screening through citations or titles and abstracts. Then the screening procedure is followed for the full texts of relevant literature. 

Charting the data : this stage of the scoping method can differ considerably based on the purpose. These details can include study characteristics, details of the populations, type and volume of relevant primary studies, details of various concepts and topics, etc. 

Collating, summarising, and reporting results : The presentation formats are also guided by the purpose of the scoping review and often consist of tabulated forms that are used to organise and chart the data accordingly. When inputs or agreements from different field experts are needed, an optional consultation step is sometimes carried out in the end.

Good practice point : For the purpose of good practice this stage should be managed by at least 2 reviewers to make sure all relevant literatures are included.  If the scoping review is intended for publication, a  protocol  should be developed before undertaking it, to outline the methods and objectives.

How to write the scope of the study?

The scope of the study refers to the elements that will be covered in a research project. It defines the boundaries of the research. The scope is always decided in the preliminary stages of a study. Deciding it in the later stages creates a lot of ambiguity regarding the research goals. The main purpose of the scope of the study is that explains the extent to which the research area will be explored and thus specifies the parameters that will be observed within the study. In other words, it enables the researcher to define what the study will cover and the elements that it will not. Defining the scope helps the researcher acquire a high level of research and writing capability.

Goals of establishing the scope of the study

The following steps can help the researcher to effectively define the goals of establishing a scope of the study.

Identification of the project or research needs

The first step is to identify the research needs. This helps them set a benchmark from the first step. Identification of the ‘what’ and ‘why’ enables the researcher to clearly set the research goals and objectives and the manner in which they will be performed.

Confirmation of the goals and objectives of the research

The goals and objectives defined in the project scope should be aligned with the SMART (Specific, Measurable, Achievable, Realistic and Timeframe) guidelines, which are:

• Specific- this involves a clear specification of what the researcher wants to achieve. It involves specifying what, why and how things will be done. This reduces the chances of ambiguities and any misunderstanding in the future.
• Measurable- Goals should be measurable and dynamic so that constant feedback can be generated for improvement.
• Achievable- Research goals should be achievable with the resources that are available.
• Realistic- Goals should be easier to deliver so that complications that can hamper the quality of the research can be avoided. Other considerations to be kept in mind are the budget and timeline.  
• Time frame- lastly, the researcher should estimate whether the set goals can be achieved within the given time frame or not.

Expectations and Acceptance

The researcher should take into account the expectations of the research and how well the findings of the researcher will be accepted by the reader. For instance, will the findings of your study help in policymaking or not?

Identification of the constraints

there are always certain roadblocks in conducting research, such as environmental conditions, technological inefficiency and lack of resources. Identifying these limitations and their possible solutions in advance help achieve goals better.

Identifying the necessary changes

After the preliminary goals are set, the researcher must carry out some part of the research so that necessary changes that lead to waste of time and resources at later stages are reduced. For example, while conducting an interview, if the researcher believes that the sample size decided is too large or too small according to the scope of the study, then the researcher can make the necessary changes in that order to avoid wastage of time and resources.

Guidelines for writing the scope of the study

The major things that the researcher should keep in mind while writing the scope of the study are as follows.

• Time period: While writing the scope of the study the researcher should first mention or state categorically the time periods the study will cover. Generally, the researchers combine the scope of the study with the limitation of the study. These things are quite interwoven. The main difference between the two is that limitations further cover the points like monetary constraints or non-cooperation from the side of the target audience.
• Geography: In addition to this another major point that the researcher should keep in mind is that the scope of the study should state the specific aspect of the data that needs to be collected like the geographic locations and the variables.
• Research population: Another major aspect that should be involved while writing the scope of the study is the sample size or the population that the researcher has selected for the study. The sampling plan must clearly indicate the sample universe, target population, profile and sample size with justification.
• Theories: The researcher should state the academic theories that are being applied to the data collected so that the reader better knows the lens of the analysis. This is presented in the ‘theoretical framework’ section.
• Purpose: The scope of the study must indicate the purpose behind it. It must briefly define the larger picture, i.e. the overall goal the researcher is trying to achieve.  
• Limitations: It is impossible to avoid roadblocks in research. Every research is restricted in scope and is subjected to certain limitations. By acknowledging these limitations and how they are restricting the study makes its findings even more credible.

Consider the topic ‘Analysis of the role of social media on the educational development in India from 2000-2015’. The scope of the study for this research topic should include several roles within the mentioned time period. Further, it should also cover the mass media types that have been used in the analysis of the study also including the location and the sample size as well.

Scope of the study

With the increase in the number of social media users and its use in everyday communication at the individual and organizational levels, there has been a corresponding increase in its incorporation in educational development and especially in a country like India. In view of this situation, the present study analyzes the role of social media on the educational development of students. To this end, the study will also cover the changes in the usage of social media in the educational field over the time period ranging from 2000-2015. The scope of the study is restricted to select social media platforms, specifically Facebook, Twitter and YouTube. The empirical study in this research is restricted to five universities located across India, wherein the opinions of 30 teachers were studied in interview sessions. Further, the study also involves an analysis of students’ perspectives on the role of social media in education from the same university. Therefore the scope of this study is limited to India, and more specifically to those offering Arts and Science-related courses.

• Describe the field of biological science

The Study of Life

Biology is a natural science concerned with the study of life and living organisms. Modern biology is a vast and eclectic field composed of many specialized disciplines that study the structure, function, growth, distribution, evolution, or other features of living organisms. However, despite the broad scope of biology, there are certain general and unifying concepts that govern all study and research:

• the cell is the basic unit of life
• genes (consisting of DNA or RNA) are the basic unit of heredity
• evolution accounts for the unity and diversity seen among living organisms
• all organisms survive by consuming and transforming energy
• all organisms maintain a stable internal environment

Biological research indicates the first forms of life on Earth were microorganisms that existed for billions of years before the evolution of larger organisms. The mammals, birds, and flowers so familiar to us are all relatively recent, originating within the last 200 million years. Modern-appearing humans, Homo sapiens , are a relatively new species, having inhabited this planet for only the last 200,000 years (approximately).

History of Biological Science

Although modern biology is a relatively recent development, sciences related to and included within it have been studied since ancient times. Natural philosophy was studied as early as the ancient civilizations of Mesopotamia, Egypt, the Indian subcontinent, and China. However, the origins of modern biology and its approach to the study of nature are most often traced back to ancient Greece. (Biology is derived from the Greek word “bio” meaning “life” and the suffix “ology” meaning “study of.”)

Advances in microscopy also had a profound impact on biological thinking. In the early 19th century, a number of biologists pointed to the central importance of the cell and in 1838, Schleiden and Schwann began promoting the now universal ideas of the cell theory. Jean-Baptiste Lamarck was the first to present a coherent theory of evolution, although it was the British naturalist Charles Darwin who spread the theory of natural selection throughout the scientific community. In 1953, the discovery of the double helical structure of DNA marked the transition to the era of molecular genetics.

Science and Pseudoscience

Science is a process for learning about the natural world. Most scientific investigations involve the testing of potential answers to important research questions. For example, oncologists ( cancer doctors) are interested in finding out why some cancers respond well to chemotherapy while others are unaffected. Based on their growing knowledge of molecular biology, some doctors suspect a connection between a patient’s genetics and their response to chemotherapy. Many years of research have produced numerous scientific papers documenting the evidence for a connection between cancer, genetics, and treatment response. Once published, scientific information is available for anyone to read, learn from, or even question/dispute. This makes science an iterative, or cumulative, process, where previous research is used as the foundation for new research. Our current understanding of any issue in the sciences is the culmination of all previous work.

Pseudoscience is a belief presented as scientific although it is not a product of scientific investigation. Pseudoscience is often known as fringe or alternative science. It usually lacks the carefully-controlled and thoughtfully-interpreted experiments which provide the foundation of the natural sciences and which contribute to their advancement.

• Biology has evolved as a field of science since it was first studied in ancient civilizations, although modern biology is a relatively recent field.
• Science is a process that requires the testing of ideas using evidence gathered from the natural world. Science is iterative in nature and involves critical thinking, careful data collection, rigorous peer review, and the communication of results.
• Science also refers to the body of knowledge produced by scientific investigation.
• Pseudoscience is a belief presented as scientific although it is not a product of scientific investigation.
• pseudoscience : Any belief purported to be scientific or supported by science that is not a product of scientific investigation.
• science : A process for learning about the natural world that tests ideas using evidence gathered from nature.
• Biology : A natural science concerned with the study of life and living organisms.

What is Project Scope Management?

• Written by John Terra
• Updated on May 14, 2024

A well-organized project stands a better chance of succeeding and doing so on time and within budget. Project managers dream of overseeing a project with no nasty surprises, running smoothly, and making everyone happy when finished. However, to achieve this state of bliss, the project manager must identify and understand the project’s chief characteristics. Or, to put it briefly, the project’s scope.

This article explores project scope management. We will discuss its definition, importance, steps involved, why it’s needed, and valuable tips, including a project management program professionals can take to hone their skills.

Project scope management is a procedure that helps managers determine and document the project’s goals, deliverables, tasks, deadlines, and budget as a part of the planning process. It’s common for large projects to require modifications along the way.

If the project’s scope is defined right at the start, it becomes considerably easier for project teams to manage and institute the required changes.

Why is Project Scope Management Important?

Keeping track of stakeholders and client expectations is one of the most daunting tasks in project management. However, project managers with a set timeline and clear scope can easily ensure that deadlines are followed and production time is efficiently used during the project’s life cycle.

Project scope management also helps avoid a few common issues, such as:

• Failure to meet project deadlines
• Having to change the project’s direction after it’s well underway
• Realizing that the project’s result was less than anticipated
• Regularly changing requirements
• The need to revisit budget discussions

Scope management is a must for long-term project management. The process makes estimating the amount of time, labor, and funds needed to accomplish the project more manageable. Ultimately, scope is a vital component of project management since it sets parameters to accommodate the constantly changing aspects of the project’s life cycle.

Project Scope Statement in Project Management

The project’s scope statement is also known as the scope document or statement of work. Here are the things a good project scope statement does:

• It details all the project’s boundaries while establishing the team’s responsibilities
• It defines all the procedures that must be followed to verify and approve the finished work
• It provides team members with a definitive guideline for making project-related decisions

Team members and stakeholders must be as specific as possible when documenting a project’s scope to avoid scope creep. Scope creep occurs when some project parts require more effort and time than initially discussed, thanks to poor planning or miscommunication.

With effective project management, however, teams can ensure that the project is finished by the deadline, an appropriate project communication plan is created, and the resulting product aligns with the team’s and organization’s initial requirements.

The Steps Involved in Project Scope Management

Define the project needs.

Defining the project’s needs is the initial step in establishing the project’s timeline, allocating project resources, and setting up the project goals. Only with these defined steps will you fully understand the work that needs to be done. Once the steps are done, team members can be allocated tasks and given guidance and direction to deliver the project in the assigned \time and budget.

Understand the Project Objectives

Before defining the project scope, it is essential first to establish the project’s objectives. These objectives may include creating an entirely new product, creating a new service within the company, or developing a new software application. There are often situations where several objectives could be central to the project. But whatever the case, regardless of the number of objectives, the project manager must ensure that the team produces the results according to the specified functions or features.

Define the Project Scope

The resources and production hours needed to create a product or service define the project’s scope, which usually outlines the goals that must be met to achieve satisfactory results.

The steps for defining project scope include:

• Available resources
• Project objectives
• Specific tasks
• Schedule/Timeline

The Project Scope Management Process

Here are the steps in the project management process.

Planning Scope Management

The initial process in project scope management involves creating a scope plan document that can be referred to in later stages. The document helps the team define, manage, validate, and control the project’s scope. The document includes:

• A detailed project scope statement
• A breakdown of all the project requirements
• The expected project deliverables
• The project change control process

This document doesn’t have to be detailed if it suits the purpose. Teams and managers can also use an earlier project’s scope management plan as a reference or template.

Collecting Requirements

The next step in the process is to work out the stakeholder requirements and expectations. Project managers must document all expectations, requirements, budgets, and deliverables via interviews, surveys, and focus groups. This is a crucial step because stakeholders often have unrealistic expectations or requirements, and the project managers would be obligated to step in to find an equitable compromise or solution that’s acceptable to everyone. Investing the time to handle this issue will head off potential project delays. At the end of this stage, the project manager should have the following:

• All business requirements
• All stakeholder requirements
• Functional as well as non-functional requirements
• Any support and training requirements
• Overall project requirements

Defining the Scope

At this step, the project manager must turn the requirements into a well-detailed description of the product or service the team is trying to deliver via the project. Once this is accomplished, there will be a project scope statement that the team can refer to throughout the project. While it is essential to list what is in the project’s scope, it’s just as important to note what lies outside it. As a result, any additions or modifications to the scope would have to go through the whole change control process to ensure the team focuses only on things they should work on rather than getting distracted by frivolous changes. With a defined scope, the manager has a reference point for the project’s team and other parties involved.

Making a Project Breakdown Structure

As the name suggests, the project breakdown structure is a document that breaks down all the work that must be done in the project and then assigns every task to the appropriate team members. The document also lists the deliverables that must be completed and their respective deadlines. Managers and teams can turn to project management software for this process step. The software makes assigning and prioritizing project tasks easier, simplifying tracking of the project’s progress and avoiding unnecessary bottlenecks.

Validating Scope

In this step, the scope and all recorded deliverables need to be sent to the project executives, management, and stakeholders to obtain the necessary approvals. Scope validation must be done before starting the project to ensure that, should something go wrong, it will be easy to find what went wrong.

Controlling Scope

Finally, project managers must ensure that, as the project begins, it always remains within the defined scope. The team should follow the proper change control if some aspects need changing.

Helpful Tips for Project Scope Management

Here’s a handful of helpful tips to facilitate project scope management.

• Avoid ambiguity in your scope to avoid unnecessary work and stress. Define the scope as clearly as possible.
• Create a Work Breakdown Structure (or WBS for short), which breaks down the scope statement into smaller, more manageable parcels.
• Ensure that the scope document is not changed during project execution. This prevents any increases in scope beyond what was initially agreed upon.
• Make the scope-defining process collaborative to prevent misunderstandings and misinterpretations of project requirements. Managers should use project collaboration tools to facilitate effective communication between the project teams.
• Finally, take the time to consult all the relevant stakeholders and management to define the project scope, which should remain the same once finalized.

Why Do Project Managers Need Scope Management?

We already understand that the project manager takes the lead in getting the project off the ground and completed. However, every leader needs a roadmap, a set of guidelines that show what needs to be done. Scope management provides managers with that roadmap.

Effective project scope management requires clear communication to ensure stakeholders and team members comprehend the project’s scope while agreeing on how the project goals will be achieved.

Good scope management helps the manager and the team avoid the pitfalls associated with a bloated scope and an unruly requirements list. Project scope clearly defines what is or is not to be included in the project and controls what can be added or removed during the project. Scope management establishes control mechanisms to address factors that may create changes during the project lifecycle.

Managers must define the project scope to estimate the needed cost and time to reach a successful conclusion.

A Project Scope Example

Let’s look at a fictitious project scope example using a template that incorporates the primary elements of a good project scope.

• Need: Purrfect Toys, Inc. needs an Android/iOS app that lets users match cat toys with their pet’s activity level and personality.
• Scope: JT’s Discount App Development will create the app for Purrfect Toys, including all appropriate algorithms and information to provide users with suitable cat toys for their pets’ needs and the functionality to buy them through the app. This includes complex data regarding cat breeds, age, activity level, and toy types.
• A working application with comprehensive data on what toys are appropriate for different cats.
• A two or three-paragraph description of each type of toy
• User profile functionality so customers can save recommendations, purchase history, and favorite products, as well as the ability to provide feedback
• Links leading to Purrfect Toys’ site allow users to purchase toys from each description.
• Exclusions:
• Logos and graphics related to the company’s business are excluded unless directly needed for the application only.
• The client’s website is outside the project’s scope; thus, Purrfect Toys must provide all links.
• Constraints: The project must be completed within six months of signing the agreement. The budget is $340,000.
• Assumptions: JT’s Discount App Development assumes Purrfect Toys has already designed and developed relevant logos, font choices, graphic designs, and key colors and has created any necessary web pages.

Driver monitoring system (DMS) was mainly developed to prevent accident risks by analyzing facial movements related to drowsiness and carelessness in real time such as driver’s gaze, blink, and head angle through cameras and warning the driver. Recently, the scope has been expanded to monitor passengers, and it has been linked to safety functions such as neglecting children, empty seats, or controlling airbags on seats with people under safety weight. However, evaluation research for algorithm advancement and performance optimization is relatively insufficient. In addition, the verification system is facing limitations such as personal information protection problems caused by the subject’s face data, errors in reproducing the subject’s drowsy and careless behavior, and differences in behavior according to individual differences. Therefore, as the importance of traffic safety is emphasized, an evaluation tool that can more efficiently and systematically evaluate the performance of DMS is needed. In this study, a driver behavior simulation dummy was developed that can quantitatively control the movement of the driver’s face and upper body. The driver behavior simulation dummy was developed in three stages in the order of function and specification definition, design and manufacture according to specifications, and verification through error tests for each function.

1 Introduction

Many drivers have experienced drowsy driving at least once while driving, and car accidents require to pay more attention behind the wheel. According to a report by the National Highway Traffic Safety Administration (NHTSA), 95% of car accidents were caused by human error. In order to prevent accidents due to human error, in the EURO NCAP and EC regulations, DMS installation has been mandated until 2022, and starting from July 2024, it will be required for all new vehicles according to the revised regulations on general vehicle safety. DMS that is able to prevent drowsy driving through in-vehicle driver monitoring are becoming increasingly important. DMS was initially developed to analyze real-time driver behavior, such as eye movements, blinking, and head angles, related to drowsiness and inattentiveness, and to provide warnings to prevent accidents [ 1 ]. Recently, the scope of DMS has expanded to include monitoring not only the driver but also the passengers, and it is being integrated with safety functions, such as controlling airbags for unattended children, vacant seats, or occupants with insufficient safety weight, through interior monitoring of the vehicle [ 2 ]. With the development of technologies that fuse steering wheel and camera information to enhance the accuracy of driver monitoring, the recognition performance of DMS has also improved [ 3 ]. DMS-related technologies are mainly evolving through camera-based artificial intelligence learning, and various evaluation studies are being conducted to validate the algorithm functionality and performance. Many cases have been observed where evaluations are conducted on actual human subjects to assess the recognition performance of DMS itself and the warning system. Some examples include inducing test subjects into drowsy states or performing inattentive behaviors to assess the recognition performance and warning effectiveness [ 4 ]. However, evaluating the recognition performance accurately is challenging in the case of assessments involving actual human subjects, as errors due to individual differences can occur during the reproduction of drowsiness and inattentive behaviors. Additionally, to obtain sufficient evaluation data, it requires continuous trial and error, which can be somewhat inefficient. The need for evaluating driver monitoring performance in real vehicles and road environments by providing visual analysis of eye conditions and head posture has been emphasized [ 5 ]. Despite various evaluation studies, including those mentioned above, that assess the recognition performance of driver gaze, accurate measurement and evaluation are challenging due to individual differences in attending visual media such as clusters or displays within the cabin environment. To investigate the individual differences in driver gaze fixation at specific points (points of interest), gaze data was measured and compared when participants observed in-cabin devices inside an actual vehicle. As shown in Fig.  1 , test subjects were instructed to observe the rearview mirror, hazard light switch, and right-side mirror for approximately 15 s each while seated in the driver's seat. Real-time gaze data was collected using wearable eye-tracking glasses (Tobii Pro Glasses 2). The results showed that even when the same target was observed, the positions and distributions of gaze varied among the drivers. Even when focusing on the relatively small area of the hazard light switch, differences were observed in the distribution of gaze. In conclusion, it is difficult to obtain accurate gaze data from a driver's eye gaze measurements due to errors over time. This means that the recognition evaluation results of the DMS algorithm may be affected by the facial movements and gaze data of different subjects. Therefore, even if the operator instructs the subject to look at a specific location, a certain amount of error is inevitable due to human factors, and it is necessary to develop an evaluation device to reduce the error caused by these human factors.

Gaze Distribution According to Individual Differences

On the other hand, most of the prior studies related to the driver simulation dummy for DMS evaluation proposed in this study used human simulation dummy to investigate the severity of human injury caused by a vehicle collision or a collision test with a pedestrian [ 6 , 7 , 8 , 9 , 10 , 11 ]. In other words, the human simulation dummy used in previous studies is a structure that cannot simulate the driver's gaze and behavior, and there is a limit to evaluating DMS. Therefore, a driver behavior simulation dummy was developed that can accurately evaluate DMS by quantitatively simulating the driver's drowsy and careless behaviors, and a series of processes such as driver behavior definition, function implementation and instrument design, and error test for dummy development are described in detail.

2 Design Functions and Specifications

2.1 scope of driver behaviors and ranges.

In order to define the driver behaviors to be emulated using the driver behavior simulation dummy, we conducted a survey of DMS development research cases and identified the specific body parts and actions of the driver that were predominantly considered in each study. Among the DMS development research cases, the most commonly considered driver behaviors were eye movements and head movements. State determination was based on the dispersion and duration of the driver's gaze, and proposed methods were suggested to improve warning strategies based on this information [ 12 ]. In research cases that considered head movements, geometric models were presented to evaluate the yaw rotation angle of the driver's head. Some studies also proposed methods for detecting cognitive dissonance by utilizing the position of the driver's lips [ 13 , 14 ]. There were also cases that utilized motion capture, tracking the movements of the driver's head and skeleton, and assessing inattentiveness based on the relative distances between joint positions [ 15 ]. By compiling the surveyed DMS development research cases, a total of six behaviors were derived: head rotation, eye rotation, eye blinking, mouth opening and closing, upper body rotation, and upper body movement. Each behavior was further classified into 12 categories based on roll/pitch/yaw rotation and X/Y/Z translation axes. Based on these results, behaviors such as eye movements, head movements, eye blinking, and upper body movements were identified. The selection of the range for each behavior was guided by referencing the EURO NCAP evaluation protocol document and DMS evaluation standardization research. The standardization research provided illumination and camera positioning for DMS evaluation, as presented in Fig.  2 , while the EURO NCAP evaluation protocol specified the specific positions that the driver focuses on for different scenarios [ 16 , 17 ].

Glance and Camera locations for DMS Evaluation

Taking into consideration the driver's gaze positions presented in the two references, we calculated the range of eye and head rotation as well as the range of upper body movement to ensure that the driver behavior simulation dummy can focus on all of these positions. The ranges for each behavior were selected, and the resolution, which is the minimum unit of control for each behavior, was determined to be as precise as possible within the specifications of the motors and mechanisms used in the development of the dummy. The finalized behaviors and specifications of the driver behavior simulation dummy are summarized in Table  1 .

2.2 Selection of Reference Points

In order to design the structural layout of the driver behavior simulation dummy, it was necessary to establish absolute reference points for the X/Y/Z axes. We selected the eye center and the Hip point as the reference points. As the dummy developed in this study is intended to be installed inside a vehicle, the absolute positions of each reference point were determined by calculating the distances along the X/Y/Z axes from the steering wheel, the cabin floor, and the rear end of the driver's seat. The internal specifications of the vehicle, which serve as the basis for dummy installation, were based on the Large Car dimensions specified in the guidelines for ergonomic vehicle design [ 18 ]. During the process of selecting the reference point positions, we referred to the dimensional data provided in the driver's seat design guidelines and also considered the anthropometric data from Size Korea to account for the sitting posture of Korean drivers. For determining the position of the Z-axis reference point, we calculated the average distance from the Hip point to the eye position of Koreans, which was defined as the difference between the eye height and the hip height. The positions of the eye center and the Hip point reference points of the dummy are summarized in Table  2 (Fig.  3 ).

Occupant Packaging Reference Dimension (H-Point: The Fundamentals of Car Design & Packaging, Stuart Macey, 2009)

3 Structure Design and Implementing Functions

3.1 structure design.

Based on the defined functions and specifications, we designed the structure of the driver behavior simulation dummy. The key components responsible for performing each function of the dummy include servo motors, a main control board, and potentiometers. The operational procedure according to the key components is as follows: when control values are inputted through dedicated software, they are transmitted to the main control board, which then controls the servo motors connected to each axis. As the servo motors perform rotational or translational movements and reach the control values inputted by the potentiometers, they come to a stop. The servo motors and potentiometers continuously provide feedback by comparing the actual motion values with the control values and adjust any discrepancies. Since there are specification differences in the key components connected to the upper body and face sections of the dummy, we designed the structure by dividing it into a base plate responsible for upper body movements and a head skull responsible for facial movements, in order to minimize interference between each part. The head skull is designed to be detachable and attachable to the base plate. The dimensions of the base plate were designed, taking into consideration the reference point positions and range of movements of the dummy, as well as the interior installation of a Large Car-sized vehicle, as shown in Fig.  4 .

Drawing of Base plate

As shown in Fig.  5 , a fixing structure was manufactured so that the base plate could be mounted to the vehicle seat position. It is in a state that can be mounted on a Genesis DH seat using this fixing structure. There is a limitation in that it is inevitable to manufacture a separate fixing structure suitable for the vehicle in order to be mounted on another vehicle. However, the base plate including the head skull was manufactured in consideration of the range of driver behavior in the seats of the passenger car (sedan) and commercial vehicle (bus).

Photo of fixing structure and in-vehicle mounting

In designing the head skull of the driver behavior simulation dummy, the focus was placed on making it as human-like as possible, as it should be recognized as a real person rather than a mannequin through DMS. To achieve this, size Korea's actual measurement data of a male in his 30 s was referenced, and the average values for the 45 facial components were calculated and applied in the design. Figure  6 shows the representative facial components applied in the head skull design.

Representative facial components for head skull design

The head skull reproduces the rotation of the driver's head and eyes, and a laser pointer was inserted into the left eye to enable real-time tracking of the eye gaze. In the process of creating the skin that wraps around the head skull, a silicone material that closely resembles human skin was utilized to ensure that it can be recognized as a real person through DMS. Figure  7 shows the confirmation of human recognition through DMS. Additionally, durability was considered to withstand external influences from the experimental environment and repetitive performance of actions. The driver behavior simulation dummy is designed for use in the vehicle interior, so an RTV silicone material that is most suitable for use at indoor temperatures was used. This material exhibits high flexibility and durability, making it commonly used for the production of items that require frequent movements, such as medical prosthetics.

Example of DMS recognition with animatronics skin

In this section, the dimensions of the base plate and head skull, as well as the specifications of the key components of the dummy according to the motion axes, were considered. The hardware specifications of the driver behavior simulation dummy are summarized in Table  3 .

3.2 Implementing Functions

To efficiently evaluate the performance of the DMS, we developed dedicated software capable of performing self-feedback of control values and behavior patternization. The dedicated software, developed using the Rubi language-based Flow Stone, consists of a graphical interface for controlling each action of the dummy and a sequencer interface for behavior patternization according to the passage of time. The action control interface is designed to control the 12 rotation and movement functions derived during the definition phase of the functionalities and specifications. Each function can be controlled within its maximum range and resolution, and animations are designed to visually confirm the dummy's actions when control values are input. Furthermore, by displaying the actual values obtained through feedback from the potentiometers, real-time verification of errors is possible. The action control interface is implemented in the form shown in Fig.  8

Behavior Control Interfaces

To facilitate the efficient evaluation of the DMS, we developed a patternization feature that allows the repetitive performance of driver actions, which can be implemented in the sequencer interface at the bottom of the software. The behavior patterns are implemented by inputting the starting and ending positions of specific actions, along with their execution time. These patterns, implemented in this manner, can be sequentially arranged in the sequencer interface to patternize various actions according to the passage of time. For example, as shown in Fig.  9 , patterns for rotating the Head Pitch by 15° and the Head Yaw by 20° can be consecutively arranged to implement a behavior pattern where the driver looks at the rearview mirror. This pattern can be repeated. In the case of implementing patterns as shown in Fig.  8 , the Pitch and Yaw axis movements occur step-by-step. However, it is also possible to implement patterns where both actions are input simultaneously, allowing them to move together. The execution time for the inputted patterns in the sequencer interface can be set with a minimum increment of 0.125 s.

4 Experiment

4.1 environment and methodology.

In order to verify the accuracy of the driver behavior simulation dummy, an error test was conducted. Although the dummy continuously displays the error between the input value and the actual control value in real time through continuous feedback between the servo motor and the potentiometer, there may be errors due to mechanical play in the dummy's mechanism. The test involved classifying the control range of each function into steps, repeatedly performing control movements at each step, measuring the actual rotation and displacement values, and comparing them with the control values inputted into the software to determine the error values. For precise measurement, the Z-axis of the driver behavior simulation dummy and the bottom surface of the base plate were arranged to be vertical and horizontal, respectively, with respect to the ground in the laboratory. The front surface of the dummy was adjusted to be parallel to the wall. To facilitate measurement, protective film was attached to the wall, allowing the distance between the fixation point indicated by the left eye laser pointer of the dummy and the distances between fixation points to be displayed. The scenarios for error testing for each movement axis of the dummy are summarized in Table  4 . Due to difficulties in accurately measuring the gaps in the eyelids and mouth opening and closing, these two actions were excluded. The measurement method for the control values of upper body movements according to the test scenarios involved marking a reference line on the underside structure surface of the base plate for X/Y/Z-axis movement values, and measuring the distance moved after control. For Pitch/Roll rotation values, a digital level was attached to the Z-axis of the base plate to measure the actual rotation. The measurement method for head movements followed the same procedure as upper body movements, where the control values were compared with the measured values after performing repeated movements according to the categorized steps. For the Roll/Pitch/Yaw rotation of the head, an eyeglass-shaped eye tracker was attached to the dummy's head, and the built-in gyro sensor measured the acceleration values, which were then converted to angular velocity values. The Pitch/Yaw rotation of the eyes was measured by utilizing the laser pointer embedded in the left eye to measure the distance between the origin point displayed on the wall and the point after movement, and by measuring the distance between the dummy's eyes and the wall to calculate the tangent value of the two distances (Figs. 10 , 11 ).

4.2 Results of Upper Body Control

The error test results for upper body movements showed an average error of 0.62° for Pitch rotation, while Roll rotation exhibited a relatively higher error of 1.12°. For the translational movements, the average errors were observed to be 0.48 mm, 0.49 mm, and 0.29 mm for the X, Y, and Z axes, respectively. The error in Z-axis movement was lower compared to the other axes (Tables 5 , 6 ).

4.3 Results of Head Control

The error test results for head movements showed an average error of 0.19° for Pitch rotation and a relatively higher average error of 1.08° for Yaw rotation of the eyes. In the case of the head skull, unlike other movement axes, the insertion space for components such as servo motors and gears are somewhat limited, and the largest clearance between components related to eye Yaw rotation was observed, which is believed to have contributed to the larger errors. For head rotation movements, the average errors were 1.67°, 1.94°, and 1.58° for Yaw, Pitch, and Roll axes, respectively, with Pitch rotation exhibiting the largest average error. This is expected as Pitch rotation is influenced the most by the weight load of the head skull among the three rotation movements. The average error of head movements was generally larger compared to other movements, which is attributed to the noise inherent in the Gyro sensor used for measuring the actual control values.

5 Conclusions and Future work

In this study, we developed a driver behavior simulation dummy that enables quantitative control of driver actions for a more systematic and efficient evaluation of DMS performance. We showed that the accuracy of the proposed apparatus through error test under condition of upper body and head control. As a result, the average error values for each movement axis of the dummy were generally lower than the resolution, indicating that precise control is achievable as a DMS evaluation tool. We believe that it can be a solution to overcome the limitations of previous driver monitoring system evaluation methods (movement errors caused by representative individual cars) using human subjects. However, some movement axes showed higher average error values than the resolution. This can be attributed to the faster rotation speed of the upper body Roll motor compared to the Pitch motor, resulting in larger errors due to speed-related influences. Additionally, the eye Yaw rotation, being the most constrained in terms of the insertion space for core components such as motors and gears, likely experienced interference and backlash, leading to significant errors. Improvements in the mechanical design are necessary for these two movement axes to minimize errors. The average error values for the three rotational movements of head Roll, Pitch, and Yaw were generally higher compared to other movement axes. However, the average error of less than 2 degrees is not unreasonable for the driver to visually recognize the type of small button (e.g., emergency lights) in the vehicle and is not expected to affect the decision of the driver's condition through DMS. In addition, the gaze position and eye movement (degree of opening and closing, frequency, etc.) used in Euro NCAP to detect carelessness and drowsiness can be implemented and verified with the proposed driver behavior simulation dummy, and detection performance evaluation can be performed in connection with various test cases. However, the lack of review of the impact on the driver behavior simulation dummy, such as control accuracy due to external environmental effects such as vibration in the actual vehicle environment, is a limitation. In the future, it is intended to verify its effectiveness as an evaluation tool by increasing the overall control accuracy of the dummy through mechanical improvement and performing performance evaluation in dynamic and static driving environments for various DMSs in real vehicles.
