How to Write a Case Study

Whether for business, academia, or research, understanding the key components of a case study will help you create a detailed and persuasive narrative.Let’s explore how to write a hook and structure a case study.

Conducting Research for a Case Study

Before writing, extensive research is essential. Gathering diverse perspectives and data sources enriches the analysis. Consider interviewing individuals directly affected by the case to gain firsthand insights. Research involves the following steps:

  • Defining the Objective: Clearly state the purpose of the case study. Determine whether the format will be written, visual, or multimedia-based.
  • Selecting a Subject: Identify a relevant case and obtain permission if necessary. Analyze the subject’s background and document contributing factors.
  • Evaluating Outcomes: Assess the potential consequences of the situation.
  • Gathering Sources: Compile credible references and highlight critical information. Exploring various research paper topics related to your subject can help frame the case study in a broader academic context.
  • Analyzing Key Issues: Focus on significant aspects of the case, examining why they exist and their impact.
  • Exploring Solutions: Develop multiple solutions based on research, discussions, and personal analysis.

Understanding the Case Study Rubric

Professors often assess case studies using similar criteria, including:

  1. Identifying core concepts and theories
  2. Applying relevant theoretical frameworks
  3. Evaluating ethical and legal principles
  4. Recognizing global significance
  5. Providing a clear summary and analysis
  6. Demonstrating critical thinking
  7. Explaining interactions between environmental and social factors
  8. Integrating theoretical knowledge with practical applications

Well-structured case studies don’t just present facts; they tell a story that engages the reader. They typically follow a narrative format.

Structuring the Case Study

To illustrate case study format, consider a study on alcohol addiction in a sample group of 30 individuals:

Problem (Act I) → Solution (Act II) → Result (Act III) → Conclusion

An example of a case study format could include the following:

Introduction:

  • Define alcoholism as a disease rather than a personal weakness.
  • Highlight its widespread impact—over 14 million people in the U.S. suffer from alcoholism.
  • Clarify terminology and introduce hypotheses, such as the link between excessive drinking and drug use.
  • Explain the study’s significance in addressing addiction-related issues.

Body:

  • Background: Explain the rationale for choosing this topic.
  • Data Analysis: Outline the research methodology, selection criteria, and interview structure.
  • Key Findings: Present statistics, including:
    • Percentage of subjects experiencing anxiety and depression
    • Age of initial alcohol use
    • Family history of alcoholism

Before you start writing, thorough research is crucial. A great case study requires digging into various sources, analyzing different perspectives and sometimes even conducting interviews.

Conclusion:

  • Summarize findings on alcoholism as a disease.
  • Recommend prevention and intervention strategies.

Writing the Case Study

Once you’ve gathered all the necessary information, it’s time to write your case study. Follow this structure to ensure clarity and coherence:

1. Introduction

The introduction sets the stage for your case study. It should include:

  • A hook – Start with a compelling fact, statistic, or question to grab attention.
  • Background information – Provide context about the case you’re studying.
  • Your objective – Clearly state the purpose of your case study.
  • A preview – Give readers a glimpse of what they can expect in the analysis.

Example of an Engaging Introduction: Imagine losing thousands of dollars due to a simple error in data entry. This was the reality for XYZ Corp before they implemented an AI-powered solution that cut human error by 80%. In this case study, we’ll explore how this transformation took place and the lessons other businesses can learn from it.

2. Problem Statement

Here, you define the main issue that the case study addresses. This section should answer:

  • What problem does the subject face?
  • Why is it significant?
  • What are the possible consequences of not addressing it?

Use real numbers, facts, and testimonials to add credibility.

3. Research and Background Information

Before presenting the solution, provide background details. This section may include:

  • Historical context
  • Key stakeholders involved
  • Previous attempts to solve the problem (if any)

4. Proposed Solutions and Implementation

Now, it’s time to present the solution:

  • What was the proposed solution?
  • How was it implemented?
  • What obstacles were faced during implementation?

Include quotes from key stakeholders, screenshots, graphs, or images to illustrate your points.

5. Conclusion

  • Summarize Key Takeaways – What did we learn from this case?
  • Future Implications – How can these insights be applied in similar situations?

Making Your Case Study Engaging

A case study isn’t just about facts—it’s about telling a compelling story. Here’s how to make yours stand out:

  • Use Real Data – Concrete statistics make your argument stronger.
    • Example: “Over 14 million people in the U.S. struggle with alcoholism, making it the third most common mental illness.”
    • Instead of: “A lot of people suffer from alcoholism.”
  • Incorporate Quotes – Adding firsthand accounts makes your study more relatable.
  • Avoid Overgeneralization – Stick to the specific case without making broad claims.
  • Address Limitations – Acknowledge any constraints in your study to add credibility.

How to Cite Your Case Study

Proper citation is essential to give credit where it’s due. Here’s how to cite a case study in different formats:

MLA (9th Edition)

Author(s). “Title of Case Study.” Title of Source, Publisher, Year, URL (if applicable). Example: Porter, Michael E. Apple Inc.: Managing a Global Supply Chain. Harvard Business Publishing, 2019.

APA (7th Edition)

Author Last Name, First Initial(s). (Year). Title of case study (Report No. if available). Publisher. URL (if online). Example: Harvard Business School. (2020). Tesla: Disrupting the Auto Industry (Case No. 9-812-141). Harvard Business Publishing.
