How to Write a Case Study: Structure, Steps and Examples
A case study analyzes one real situation and defends a decision about it. The standard structure is: problem statement, background, analysis using a named framework, two or three alternatives with trade-offs, a recommendation, and an implementation plan with metrics. The recommendation carries the grade, not the summary.
What is the structure of a case study?
Six sections in this order: problem statement, background and key facts, analysis, alternatives, recommendation, implementation. Some rubrics add an executive summary at the front, written last. Retelling the case is the most common failure, so keep background under 20 percent of your word count.
| Section | Share of words | What it must do |
|---|---|---|
| Executive summary | 5% | State the problem and your recommendation in one paragraph. Write it last. |
| Problem statement | 10% | Name the single decision to be made, not a list of symptoms. |
| Background | 15% | Only the facts your analysis will actually use. |
| Analysis | 30% | Apply a named framework to evidence from the case. |
| Alternatives | 20% | Two or three real options with quantified trade-offs. |
| Recommendation | 10% | Pick one and defend it against the alternatives you just listed. |
| Implementation | 10% | Who, by when, at what cost, measured how. |
How do you write a case study step by step?
Read for the decision first, then gather only the evidence that bears on it. Most students read for detail, drown in facts, and end up summarizing. Reading for the decision keeps every later section pointed at the same target.
- 01. Read once for the decision
Who has to decide what, by when? Write that sentence down before you take any other notes.
- 02. Read again for evidence
Mark only facts that change the decision. Ignore anything that would not alter your recommendation.
- 03. Choose a framework and apply it
SWOT, Porter's Five Forces, PESTEL, VRIO, or a financial model. Use one properly rather than three superficially.
- 04. Build the alternatives
Two or three genuinely viable options. A straw man option you obviously reject wastes your word count.
- 05. Quantify the trade-offs
Cost, time, risk and expected return per option. Numbers from the case beat adjectives every time.
- 06. Recommend and defend
Name your choice, then explain specifically why the runner-up loses.
- 07. Plan implementation
First 30, 90 and 365 days, owner per action, budget, and the metric that proves it worked.
What is a good case study problem statement?
One sentence naming the decision maker, the decision and the deadline. For example: 'The COO must decide by Q3 whether to insource last-mile delivery in three metros or renew the third-party contract for two more years.' Symptoms are not problems; declining margin is a symptom.
How do you write a nursing case study?
Same logic, clinical structure. Use patient presentation, assessment data, nursing diagnoses, planned interventions with cited rationales, evaluation and reflection. Every intervention needs a rationale from current evidence, and the reflection section is where most of the grade differentiation happens.
- ✓Patient presentation, history and objective data, de-identified
- ✓Pathophysiology of the primary condition in your own words
- ✓Two or three prioritized NANDA nursing diagnoses
- ✓Interventions with a cited evidence-based rationale each
- ✓Evaluation against measurable goals
- ✓Reflection on what you would change and why
Common case study mistakes
The four that cost the most marks are summarizing instead of analyzing, choosing a framework and never using its output, offering a recommendation without alternatives, and skipping implementation. Fixing these four moves most papers up a full letter grade without a single extra source.
- ✓Retelling the case instead of analyzing it
- ✓Running a SWOT and then ignoring what it produced
- ✓Recommending without showing what you rejected
- ✓No numbers anywhere in the trade-off discussion
- ✓Ending at the recommendation with no implementation plan
- ✓Hedging, a case study rewards a defended decision, not balance

What are the 6 parts of a case study?+
Problem statement, background, analysis, alternatives, recommendation and implementation. Many rubrics add an executive summary written last.
How long should a case study be?+
Undergraduate case studies usually run 1,000 to 2,000 words, MBA case analyses 2,000 to 4,000. Follow the rubric before any general rule.
What framework should I use for a case study?+
Match the framework to the decision: Porter's Five Forces for industry entry, SWOT for positioning, VRIO for capability, PESTEL for external risk, NPV or break-even for investment.
Do case studies need references?+
Yes, unless your professor says the case document is the only permitted source. Even then, framework citations and industry data usually strengthen the analysis.
How do you start a case study?+
Open with the decision, not the company history. State who must decide what by when, then move to the evidence.
What is the difference between a case study and a report?+
A report describes a situation. A case study analyzes one and commits to a defended decision about it.
