How to Write a Case Study: Step-by-Step Guide

Case studies are a core assessment type in business, nursing, law, psychology, and engineering courses. They test your ability to analyze real-world scenarios and apply theoretical knowledge. Here's how to write one that scores top marks.

What Is an Academic Case Study?

A case study presents a real or hypothetical scenario and requires you to analyze it using relevant theories, frameworks, and evidence. Unlike an essay, a case study focuses on a specific situation — a company, patient, legal case, or engineering problem.

Standard Case Study Structure

• Introduction: Brief overview of the case, context, and purpose
• Background: Key facts, history, and circumstances
• Problem Identification: What went wrong or what needs solving?
• Analysis: Apply theories and frameworks to analyze the problem
• Solutions / Recommendations: Propose actionable solutions
• Conclusion: Summary and key takeaways
• References: Academic sources supporting your analysis

Analysis Frameworks by Subject

Business & Management

• SWOT Analysis — Strengths, Weaknesses, Opportunities, Threats
• PESTLE Analysis — Political, Economic, Social, Technological, Legal, Environmental
• Porter's Five Forces — competitive analysis
• Ansoff Matrix — growth strategies

Nursing & Healthcare

• Roper-Logan-Tierney Model — activities of living
• ABCDE Assessment — systematic patient assessment
• Gibbs' Reflective Cycle — reflective practice

Psychology

• Biopsychosocial Model — holistic case formulation
• CBT Framework — thoughts, feelings, behaviors analysis

Writing Tips for Top Marks

1. Read the Case Material Multiple Times

First read: understand the story. Second read: highlight key facts and data. Third read: identify the core problems.

2. Use the "So What?" Test

For every point you make, ask "so what?" — connect every observation to a theoretical framework or a practical recommendation. Don't just state facts; analyze them.

3. Be Specific With Recommendations

Don't write "the company should improve marketing." Instead: "The company should invest in targeted social media campaigns on Instagram and TikTok, focusing on the 18-25 demographic, with an estimated budget of £50,000 for Q3 2026."

4. Use Data From the Case

If the case provides financial data, statistics, or timelines — use them. Professors want to see that you've engaged deeply with the material, not just written a generic analysis.

5. Balance Theory and Practice

The best case studies weave academic models and real-world application together. Don't just describe a theory — show how it applies to this specific case.

Common Mistakes

• ❌ Summarizing the case instead of analyzing it
• ❌ Using too many frameworks without depth
• ❌ Providing vague, unrealistic recommendations
• ❌ Ignoring data and figures provided in the case
• ❌ Not referencing academic sources
