What Is a Case Study?
A case study is a subcategory of research design which investigates problems and offers solutions. Case studies can range from academic research studies to corporate promotional tools trying to sell an idea—their scope is quite vast.
What Is the Difference Between a Research Paper and a Case Study?
While research papers turn the reader’s attention to a certain problem, case studies go even further. Case study guidelines require students to pay attention to details, examining issues closely and in-depth using different research methods. For example, case studies may be used to examine court cases if you study Law, or a patient’s health history if you study Medicine.
Case studies involve a lot of storytelling – they usually examine particular cases for a person or a group of people. This method of research is very helpful, as it is very practical and can give a lot of hands-on information. Most commonly, the length of the case study is about 500-900 words, which is much less than the length of an average research paper.
The structure of a case study is very similar to storytelling. It has a protagonist or main character, which in your case is actually a problem you are trying to solve. You can use the system of 3 Acts in your story. It should have an introduction, rising action, a climax where transformation occurs, falling action, and a solution.
Here is a rough formula for you to use in your case study:
Problem (Act I): > Solution (Act II) > Result (Act III) > Conclusion.
Types of Case Studies
The purpose of a case study is to provide detailed reports on an event, an institution, a place, a person, or pretty much anything. There are a few common types of case study, but the type depends on the topic. The following are the most common domains where case studies are needed:
- Historical case studies are great to learn from. Historical events have a multitude of source info offering different perspectives. There are always modern parallels where these perspectives can be applied, compared, and thoroughly analyzed.
- Problem-oriented case studies are usually used for solving problems. These are often assigned as theoretical situations where you need to immerse yourself in the situation to examine it. Imagine you’re working for a startup and you’ve just noticed a significant flaw in your product’s design. Before taking it to senior manager, you want to study the issue in detail and provide solutions. On a greater scale, problem-oriented case studies are a vital part of relevant socio-economic discussions.
- Cumulative case studies collect information and offer comparisons. In business, case studies are often used to tell people about the value of a product.
- Critical case studies explore the causes and effects of a certain case.
- Illustrative case studies describe certain events, investigating outcomes and lessons learned.
Case Study Format
The case study format is typically made up of eight parts:
- Executive Summary. Explain what you will examine in the case study. Write an overview of the field you’re researching. Make a thesis statement and sum up the results of your observation in a maximum of 2 sentences.
- Background. Provide background information and the most relevant facts. Isolate the issues.
- Case Evaluation. Isolate the sections of the study you want to focus on. In it, explain why something is working or is not working.
- Proposed Solutions. Offer realistic ways to solve what isn’t working or how to improve its current condition. Explain why these solutions work by offering testable evidence.
- Conclusion. Summarize the main points from the case evaluations and proposed solutions. 6. Recommendations. Talk about the strategy that you should choose. Explain why this choice is the most appropriate.
- Implementation. Explain how to put the strategy into action.
- References. Provide all the citations.
Setting Up the Research
When writing a case study, remember that research should always come first. Reading many different sources and analyzing other points of view will help you come up with more creative solutions. Including all of the necessary research, writing a case study may take some time. The research process involves doing the following:
- Define your objective. Explain the reason why you’re presenting your subject. Figure out where you will feature your case study; whether it is written, on video, shown as an infographic, streamed as a podcast, etc.
- Determine who will be the right candidate for your case study. Get permission, quotes, and other features that will make your case study effective. Get in touch with your candidate to see if they approve of being part of your work. Study that candidate’s situation and note down what caused it.
- Identify which various consequences could result from the situation. Follow these guidelines on how to start a case study: surf the net to find some general information you might find useful.
- Make a list of credible sources and examine them. Seek out important facts and highlight problems. Always write down your ideas and make sure to brainstorm.
- Focus on several key issues – why they exist, and how they impact your research subject. Think of several unique solutions. Draw from class discussions, readings, and personal experience. When writing a case study, focus on the best solution and explore it in depth. After having all your research in place, writing a case study will be easy. You may first want to check the rubric and criteria of your assignment for the correct case study structure.
Although your instructor might be looking at slightly different criteria, every case study rubric essentially has the same standards. Your professor will want you to exhibit 8 different outcomes:
- Correctly identify the concepts, theories, and practices in the discipline.
- Identify the relevant theories and principles associated with the particular study.
- Evaluate legal and ethical principles and apply them to your decision-making.
- Recognize the global importance and contribution of your case.
- Construct a coherent summary and explanation of the study.
- Demonstrate analytical and critical-thinking skills.
- Explain the interrelationships between the environment and nature.
- Integrate theory and practice of the discipline within the analysis.
Case Study Outline
Let’s look at the structure of an outline based on the issue of the alcoholic addiction of 30 people.
- Statement of the issue: Alcoholism is a disease rather than a weakness of character.
- Presentation of the problem: Alcoholism is affecting more than 14 million people in the USA, which makes it the third most common mental illness there.
- Explanation of the terms: In the past, alcoholism was commonly referred to as alcohol dependence or alcohol addiction. Alcoholism is now the more severe stage of this addiction in the disorder spectrum.
- Hypotheses: Drinking in excess can lead to the use of other drugs.
- Importance of your story: How the information you present can help people with their addictions.
- Background of the story: Include an explanation of why you chose this topic.
- Presentation of analysis and data: Describe the criteria for choosing 30 candidates, the structure of the interview, and the outcomes.
- Strong argument 1: ex. X% of candidates dealing with anxiety and depression…
- Strong argument 2: ex. X amount of people started drinking by their mid-teens.
- Strong argument 3: ex. X% of respondents’ parents had issues with alcohol.
- Concluding statement: I have researched if alcoholism is a disease and found out that…
- Recommendations: Ways and actions for preventing alcohol use.
Writing a Case Study Draft
After you’ve done your case study research and written the outline, it’s time to focus on the draft. In a draft, you have to develop and write your case study by using: the data which you collected throughout the research, interviews, and the analysis processes that were undertaken. Follow these rules for the draft:
- Your draft should contain at least 4 sections: an introduction; a body where you should include background information, an explanation of why you decided to do this case study, and a presentation of your main findings; a conclusion where you present data; and references.
- In the introduction, you should set the pace very clearly. You can even raise a question or quote someone you interviewed in the research phase. It must provide adequate background information on the topic. The background may include analyses of previous studies on your topic. Include the aim of your case here as well. Think of it as a thesis statement. The aim must describe the purpose of your work—presenting the issues that you want to tackle. Include background information, such as photos or videos you used when doing the research.
- Describe your unique research process, whether it was through interviews, observations, academic journals, etc. The next point includes providing the results of your research. Tell the audience what you found out. Why is this important, and what could be learned from it? Discuss the real implications of the problem and its significance in the world.
- Include quotes and data (such as findings, percentages, and awards). This will add a personal touch and better credibility to the case you present. Explain what results you find during your interviews in regards to the problem and how it developed. Also, write about solutions which have already been proposed by other people who have already written about this case.
- At the end of your case study, you should offer possible solutions, but don’t worry about solving them yourself.
Use Data to Illustrate Key Points in Your Case Study
Even though your case study is a story, it should be based on evidence. Use as much data as possible to illustrate your point. Without the right data, your case study may appear weak and the readers may not be able to relate to your issue as much as they should. Let’s see the examples:
With data: Alcoholism is affecting more than 14 million people in the USA, which makes it the third most common mental illness there.
Without data: A lot of people suffer from alcoholism in the United States.
Try to include as many credible sources as possible. You may have terms or sources that could be hard for other cultures to understand. If this is the case, you should include them in the appendix or Notes for the Instructor or Professor.
Finalizing the Draft: Checklist
After you finish drafting your case study, polish it up by answering these “ask yourself” questions and think about how to end your case study:
- Check that you follow the correct case study format, also in regards to text formatting.
- Check that your work is consistent with its referencing and citation style.
- Micro-editing — check for grammar and spelling issues.
- Macro-editing — does “the big picture” come across to the reader? Is there enough raw data, such as real-life examples or personal experiences? Have you made your data collection process completely transparent? Does your analysis provide a clear conclusion, allowing for further research and practice?
Problems to avoid:
- Overgeneralization – Do not go into further research that deviates from the main problem.
- Failure to Document Limitations – Just as you have to clearly state the limitations of a general research study, you must describe the specific limitations inherent in the subject of analysis.
- Failure to Extrapolate All Possible Implications – Just as you don’t want to over-generalize from your case study findings, you also have to be thorough in the consideration of all possible outcomes or recommendations derived from your findings.
How to Create a Title Page and Cite a Case Study
Your title page depends on the prescribed citation format.
The title page should include:
- A title that attracts some attention and describes your study
- The title should have the words “case study” in it
- The title should range between 5-9 words in length
- Your name and contact information
- Your finished paper should be only 500 to 1,500 words in length. With this type of assignment, write effectively and avoid fluff.
There are some cases when you need to cite someone else’s study in your own one – therefore, you need to master how to cite a case study. A case study is like a research paper when it comes to citations. You can cite it like you cite a book, depending on what style you need.

To conclude, a case study is one of the best methods of getting an overview of what happened to a person, a group, or a situation in practice. It allows you to have an in-depth glance at the real-life problems that businesses, healthcare, criminal justice, etc. may face. This insight helps us look at such situations in a different light. This is because we see scenarios that we otherwise would not, without necessarily being there.
