How to Write a Case Study — UK University Guide
UK Academic Writing Guide | Reviewed by the Projectsdeal Editorial Team | Updated June 2026
Quick AnswerA case study applies theory to a real (or realistic) scenario. To write one: (1) read the case and identify the key problems, (2) link them to relevant theory and frameworks, (3) analyse causes and options with evidence, and (4) give clear, justified recommendations. Use headings, and focus on analysis and application — not just describing the case.
Overview
Case studies are common in business, nursing, law and management. They test whether you can apply academic concepts to a practical situation. Unlike an essay, a case study usually uses headings and ends with recommendations.
How to Write a Case Study: Step by Step
Read and understand the case
Identify the context, the key issues or decisions, and what the question actually asks you to do.
Identify the core problems
Separate symptoms from root causes. Prioritise the issues that matter most.
Apply theory and frameworks
Use relevant models (e.g. SWOT, PESTLE, Porter, clinical frameworks) to analyse the situation.
Analyse with evidence
Evaluate options and causes using evidence from the case and academic sources, not opinion.
Give recommendations
Propose clear, realistic, justified actions, and note how they would be implemented and measured.
Structure of a Case Study
A typical structure: introduction, background/context, analysis (the largest part, often using frameworks), findings, recommendations, and conclusion. Use headings, and keep description brief so most of the word count is analysis and recommendations.
Common Mistakes to Avoid
Just describing the caseRe-telling the scenario without analysis. Apply theory and evaluate.
Generic frameworksUsing SWOT/PESTLE superficially. Draw specific, evidenced insights from them.
Vague recommendations‘Improve communication’ is weak. Be specific, realistic and justified.
No links to theoryCase studies test application of concepts — reference relevant models and sources.
Frequently Asked Questions
How is a case study different from an essay?
A case study applies theory to a specific scenario, usually uses headings, and ends with recommendations, whereas an essay builds a continuous argument without subheadings.
What frameworks are used in case studies?
It depends on the subject — SWOT, PESTLE, Porter's Five Forces and the marketing mix in business; clinical models and care frameworks in nursing; IRAC in law.
How do I write recommendations?
Make them specific, realistic and justified by your analysis, and briefly explain how each would be implemented and its impact measured.
How long should a case study be?
Follow the brief. Whatever the length, keep description short and devote most of the word count to analysis and recommendations.
