This guide explains how to write a descriptive case study. A descriptive case study describes
how an organization handled a specific issue. Case studies can vary in length and the amount of
details provided. They can be fictional or based on true events.
Why should you write one? Case studies can help others (e.g., students, other organizations,
employees) learn about:
- new concepts,
- best practices, and
- situations they might face.
Writing a case study also allows you to critically examine your organizational practices.
Examples
The following pages provide examples of different types of case study formats. As you read
them, think about what stands out to you. Which format best matches your needs? You can
make similar stylistic choices when you write your own case study.
