How to Write a Case Study: Definition, Outline, Steps & Examples

What Is a Case Study: Definition

A case study is a research method that involves examining a specific instance to let researchers learn more about an individual, event, organization or concept. It is like a magnifying glass for studying real-life situations. By looking at a single example, we can learn more about complex issues and understand patterns. 

Case studies are used in the fields like Psychology, Business, Statistics or Nursing. As a rule, students apply this research method when writing a dissertation or thesis. 

Depending on the research question and the data needed to address a problem, case studies can involve various research methods.

Research Methods Applied in Case Studies

Case Study Example

A researcher is interested in studying the effects of a newly implemented teaching method on student performance. To find out, they observe a class of 30 students over one semester. The researcher compares the test scores from before and after the method was used, documenting its effectiveness. 

The study results showed that academic performance had improved by 11.5% since the new teaching method was implemented. The researcher concluded that this approach works well and can be generalized to a broader population.

Let's recap the main points. 

What Is the Purpose of a Case Study?

The primary purpose of a case study is to gain insight into the real-world situations through the investigation and analysis of a single instance. This research design is often applied to meet such goals: 

• Develop a better understanding of complex issues or phenomena 
• Identify patterns and relationships
• Test hypotheses and theories in natural settings
• Provide practical solutions
• Illustrate best practices or successful strategies.

Every case study writer can customize their work to fit the needs of a specific discipline, as shown below.

Types of Case Studies

There are different types of case studies that scholars or students can bring into play. Each approach has its own focus and is chosen based on research objectives. 

1. Descriptive case studies This approach involves a detailed examination of a particular situation or phenomenon to understand it better. Here, researchers see the context, events, and processes that led to a particular outcome, and get a comprehensive picture of the situation.
2. Explanatory case studies Explanatory method allows us to understand the "why" and “how” behind a particular event or phenomenon. As the name suggests, this type of case study seeks to test and explain the causal relationship between independent and dependent variables. 
3. Exploratory case studies Imagine being a detective and investigating a mystery or problem in its early stages. This is the main idea of an exploratory investigation. It helps to recognize key questions, potential patterns, and areas for further research. It's like peeling back the layers of an onion, revealing new insights and uncovering possible solutions. 
4. Intrinsic case studies Unlike other case study methods, an intrinsic approach is used to explore a unique instance. Here, researchers focus on a particular scenario in its own right, rather than trying to apply the outcomes to a broader population. 
5. Instrumental case studies This type of study examines one instance to shed light on a larger group or phenomenon. Instrumental technique is a good choice if you want to develop theoretical frameworks and obtain generalizable findings.
6. Cumulative case studies While conducting cumulative research, students compile and synthesize information from multiple similar instances. Here, you combine the results of multiple studies to draw more generalized conclusions.
7. Collective case reports Think of several individual instances being studied together to provide a broader understanding of a specific phenomenon. These instances are often connected by a common theme. This enables researchers to compare and contrast cases and uncover tendencies. 
8. Critical case studies Researchers use this method to explore exceptional instances that are particularly interesting or thought-provoking. Critical approach helps to analyze why a specific situation occurred and what could have been done differently.

Case Study Structure: Main Parts

When investigating any phenomenon, it’s important to organize your sections in a logical manner. A structure of a case study usually includes such components:

• Introduction This section is a place to present a case. Provide a brief overview of your instance, introduce your key research objectives and prepare the readers for further analysis.
• Problem identification By laying out a problem, you will be able to show the scope and significance of your topic. Identify the main issue that will be examined and build a clear statement of the problem.
• Background A properly established context sets the stage for research and lays a foundation for case evaluation. Offer relevant background information on the instance. This can be a historical, geographical or cultural context.
• Methodology Describe your methodology in research – approach, data collection methods and analysis techniques used in your investigation.
• Solution  Now is the time to determine potential solutions to address the problem, and evaluate the pros and cons of each resolution. Make sure solutions are realistic.
• Results Once a case study is conducted, you should share your key findings. Mention any data or evidence that was collected and analyzed.
• Discussion This part of a case study is a perfect opportunity for analysis. Discuss the implications of your outcomes and draw conclusions
• Conclusion Summarize your main points, restate a problem and solutions, and offer final recommendations or next steps.

How to Write a Case Study in 7 Steps?

Now that you are familiar with the preparation stages, it's time to dive into the writing process. Writing case studies can be challenging. But by following a structured approach, you can produce a clear and engaging work. 

To create a strong project, it's important to carefully plan and execute each step of your flow, from identifying the research question to presenting your conclusions. Below we have prepared detailed guidelines on how to write a case study paper. 

1. Introduce a Case Study

Start your case study introduction by presenting your subject and providing a brief overview of the research objectives. It's important to highlight the significance of your case and explain why it warrants examination. One way to do this is to focus on innovative aspects, such as a novel approach to a problem or a new technology. You can also emphasize the broader implications. 

You should also preview a structure. This will give readers an idea of what to expect. Briefly describe your main points or provide a rough outline. 

Case Study Introduction Example

Post-traumatic stress disorder (PTSD) is a debilitating condition that can arise in individuals who have experienced a traumatic event. In this case study, we examine the experiences of a patient who was diagnosed with PTSD following a car accident. Our analysis focuses on the patient's symptoms, including intrusive thoughts, hyperarousal, and avoidance behaviors. We also explore the treatments employed to manage these symptoms. By analyzing this case, we aim to provide insights into the challenges of treating PTSD and offer recommendations for improving therapeutic interventions for individuals suffering from this condition.

2. Describe a Problem

Before you get to the problem, provide context that explains the issue at hand. Identify the scope and impact of this problem. One efficient strategy of creating case studies that trigger attention is integrating examples or statistics. This helps to understand how severe this situation is. 

Additionally, you may want to highlight any challenges or obstacles that have prevented a problem from being solved. 

Example of Problem Description in a Case Study

John is a 28-year-old man who was involved in a serious car accident three months ago. Since then, he has been experiencing PTSD symptoms, including recurring nightmares, flashbacks, and feelings of anxiety. These symptoms have affected his work performance and relationships with family and friends. Despite seeking help from his primary care physician and attending therapy sessions, John has not experienced significant improvement. The challenge is to identify effective treatments that can help John manage his PTSD and improve his quality of life.

Example of How to Describe Research Methods 

In this research, both quantitative and qualitative data were utilized. 10 semi-structured interviews were conducted with participants who had experienced PTSD symptoms following a traumatic event. Additionally, data was collected from a survey of 253 individuals who had not been diagnosed with PTSD. We inquired about their experiences with trauma and the types of coping strategies they used to manage stress. Medical records from John's primary care physician were analyzed to track his progress over time. The combination of quantitative and qualitative data allowed for a comprehensive understanding of John's unique experiences with PTSD.

4. Offer Solutions to the Problem 

The next stage involves coming up with potential solutions. Explain what strategies could be used to address the problem.

For example, if you write a case study on a business-related problem, solutions may involve implementing procedures to improve efficiency. Alternatively, in a healthcare niche, you will offer a new medication or therapy.

Be sure to provide evidence from your research or expert opinions to support your suggestions.

Here’s how to do a case study solutions section. 

Example of Solution

One potential solution for addressing John's PTSD symptoms is cognitive-behavioral therapy (CBT). According to a study by Bisson and colleagues (2013), CBT has been found to be effective in reducing symptoms of PTSD in individuals who have experienced traumatic events. The therapist can work with John to identify and challenge negative thought patterns related to his traumatic experience and teach him coping skills to manage his anxiety and stress.

5. Present Your Key Results

Most scholars judge case study reports by research outcomes. You need to show that your solution works. Analyze collected data and share your most significant findings in your results section. This can be an increase in profits or a patient's health improvement. 

When you write your case study outcomes, it is important to organize the information in a clear and concise manner. Use tables, graphs and charts to illustrate your data visually. 

Provide a short summary of your results and their implications. But don’t just tell. You need to back up your research with evidence. If you used interviews, be sure to include any statistical analysis done for those results. 

Example of Case Study Research Results

Our analysis showed that participants who received cognitive-behavioral therapy (CBT) reported a significant decrease in symptoms of post-traumatic stress disorder (PTSD), as compared to those who received no therapy. Specifically, the group who received CBT experienced a 35% reduction in symptoms. Meanwhile, the control group experienced no significant change. These findings suggest that CBT may be an effective treatment option for individuals with PTSD.

6. Conclude with Recommendations

A conclusion of a case study is where you wrap everything up and provide recommendations for further research. Sum up your key points and explain how they could be used to solve similar problems. You can also highlight any unexpected findings or insights that emerged during the study. Don’t forget to discuss any ethical considerations or limitations. 

You need to create a lasting impression. For this, end a case study with a thought-provoking statement or call to action. 

Case Study Conclusion Example

Our research highlighted the significant impact of PTSD on individuals who have experienced a traumatic event. The results suggested that cognitive-behavioral therapy and reprocessing therapy are effective treatments for PTSD. However, more research is needed to determine the long-term effects of these treatments. Additionally, the stigma surrounding mental health and seeking treatment remains a significant barrier to access to care. It is crucial for healthcare professionals and policymakers to address this issue and increase access to mental health services.
