How to write a case study analysis: format, steps and an example

Short answer

A case study analysis reads a real or realistic situation, separates the core problem from its symptoms, weighs a few possible solutions against the evidence in the case, and argues for one recommendation with a plan to carry it out. The marks go to judgement, not to retelling the case.

First, which kind of case study?

Two different assignments share the name. A case analysis gives you a scenario, often from business, social work, education or public administration, and asks what should be done. A case study research paper asks you to choose a person, place, event or phenomenon and study it in depth to learn something about a wider research problem. The University of Southern California Libraries separate the two clearly: a case analysis is a teaching method built around a set scenario, while a case study is a research design that you choose and justify.

Most students searching for "how to write a case study" have been handed a case analysis, so that is what most of this guide covers. If you are designing your own case study research, the structure looks more like a research proposal followed by a report.

Case study format

The format below follows the order USC's guide recommends for a case analysis paper. Your course may merge or rename sections; keep the order of thinking even if the headings change.

Sections of a case analysis paper
SectionWhat it does
IntroductionThe main facts, the setting and the core problem, and how the paper is organised
Background analysisThe stakeholders, their assumptions, demands and concerns, each tied to evidence in the case
ProblemsEvery problem, ranked: what must be fixed now, what can wait, what can be set aside
Alternative solutionsTwo or three realistic options, each with the evidence for and against it
RecommendationThe option you choose, how to carry it out, who is responsible and how success is measured
ConclusionA short synthesis that links the case to your course reading

Finding the real problem

Read the case twice. The first time, read quickly for the overall situation. The second time, read slowly with notes: who the stakeholders are, what each one wants, what each one assumes, and which facts seem to contradict each other. Cases often include information that is irrelevant or misleading on purpose, to test whether you can sort it out.

Then separate symptoms from the core problem. Falling sales, staff leaving and angry customers may all be symptoms of one problem, such as a pricing change nobody explained. USC's guide warns that the most common error is recommending a solution before you have shown you understand the problem. State the core problem in one sentence, then point to the evidence in the case that supports it.

Analysing options

Case analyses rarely have one correct answer. What markers look for is a fair comparison. For each option, set out what it would fix, what it would cost, the risks, and the difference between its short and long-term effects. Use the course's theories and models where they help you judge, not as decoration.

Keep the analysis tied to the facts you were given. If the case does not say something, do not assume it. And avoid arguing about what should have happened in the past: the scenario has already happened, and your job is to say what to do next.

Recommendation and implementation

Choose one option and argue for it. Then turn it into a plan: the steps, who carries out each one, the order, and how you will know it is working. USC's guide stresses specific, measurable recommendations and asks you to anticipate the obstacles and new problems your plan could create.

Address the strongest objection to your choice directly. A recommendation that admits its risks and explains why it is still the best option is more persuasive than one that claims to have none.

Worked example

The case below is invented for this guide. A small bookshop has lost a third of its weekday customers in a year. Staff blame a new chain store nearby; the owner blames online shopping.

An annotated case analysis outline
StepWhat the student wroteWhy it works
Core problemThe shop cut its weekday opening hours to save staff costs, and weekday regulars, most of them retirees, moved their habits elsewhere.Points to evidence in the case (the rota change and the timing of the drop) rather than repeating staff opinion.
OptionsRestore the hours; add a weekly reading group to bring regulars back; or accept the loss and focus on weekends.Three realistic options, each weighed on cost and risk.
RecommendationRestore two mornings a week and launch the reading group on one of them; review footfall after eight weeks.Specific, affordable, and measurable, with a date to check it.

Before you hand it in

Check three things. Is the background short and only about what matters later? Is every claim tied to something in the case? Is the recommendation specific enough that someone could act on it tomorrow?

AI tools can help you summarise a long case or list theories to consider, but the judgement is the part being marked. See case study analysis with AI for what is usually allowed. For a paper that judges a book rather than a situation, see the book review guide, and for other paper types the guides.

FAQ

What is the difference between a case study and a case analysis?

A case analysis gives you a scenario and asks what should be done. A case study research paper studies a chosen case in depth to understand a wider research problem.

How long should the background section be?

Short. Summarise only the facts that matter later in the paper; markers already know the case.

Can I use outside sources in a case analysis?

Only if your instructor allows it. Many case analyses are meant to be answered from the case and the course readings alone.

Is there one right answer to a case study?

Rarely. Marks go to a clear problem statement, a fair comparison of options and a specific, well-argued recommendation.

This guide explains common rules; your institution's policy decides what is allowed on your work.
