What the format actually is
The Harvard Business School case study format is the template behind most teaching cases used in business classrooms worldwide: a narrative built around one organisation at one moment of decision, followed by exhibits, and ending without a conclusion. HBS did not invent the case method alone, but it standardised the modern teaching case — thousands are distributed through its publishing arm and read across MBA programmes, executive courses and increasingly undergraduate modules. Because the format travels so far beyond Cambridge, Massachusetts, the phrase now describes a genre as much as a product.
Independence note. This is an independent study guide. CaseStudyWriting.com is not affiliated with Harvard University or Harvard Business School; no endorsement is implied, and we don't distribute or resell Harvard cases. The format is described here so you can read, discuss and analyse the cases your course assigns.
Why does the format matter to you? Because every part does a job, and knowing the job tells you where the marks and the cold-call questions live. Explore the six parts below — each card pairs what the part does with what you should do about it.

Reading a 15-page case the way you read a chapter is how cold calls get won by other people. Five passes, in this order:
- Pass 1 — the plot (5 minutes). First page, last page, headings. Who is the protagonist, what decision is on the table? Write one sentence before moving on.
- Pass 2 — the evidence (20–30 minutes). Full read, annotating only two things: facts you'd cite, and questions you'd ask. Underline numbers; the case put them there on purpose.
- Pass 3 — the exhibits (15 minutes). Compute at least one: margins, growth rates, ratios the text only implies. Your margin arithmetic is your ticket into the discussion.
- Pass 4 — the position (10 minutes). Choose. Write your recommendation in two sentences, plus the strongest argument against it. This paragraph is your cold-call insurance.
- Pass 5 — the rehearsal (5 minutes). Say the position aloud, once. If you stumble on the "because", the position isn't ready; tighten it until one breath carries it.
For the classroom side — preparation rituals, issue trees, handling cold calls — our guide to preparing for business case studies goes deeper, and the presentation guide covers the day you're on the presenting end. When an exhibit deserves a full framework treatment, the SWOT builder, PESTLE generator and Five Forces generator all export clean text you can paste into prep notes.
Worked mini-outline: the one-page prep sheet
Here's the prep sheet format the 5 passes fill in. The example entries reference a fictional case — "Harbourline Ferries" — so everything shown is illustrative.
PREP SHEET — Harbourline Ferries (fictional, illustrative) 1. Decision: Should the CEO upgrade the two older vessels now or wait for the peak season's cash? 2. Protagonist: the managing director; a board meeting in three weeks. 3. Three facts I can cite: - Bookings are seasonal (exhibit 1 shows the summer spike) - The competitor added a vessel last year - Maintenance costs doubled between the two full years shown 4. One computed exhibit: - Exhibit 2: margin falls from 14% to 9% as fuel costs rise 5. My position (2 sentences): Upgrade the older vessel now and charter, not buy, the second. The safety and reliability risk hits the corporate contracts that carry the winter months. 6. Strongest counter-argument + my answer: "Wait and keep cash" — but a breakdown in peak season costs more than the interest on financing, per exhibit 3's downtime figures. 7. Two questions for the class: - What would the board need to see to approve a charter? - Is the fuel trend cyclical or structural?
Cold call vs written assignment: same case, different answers
A cold call wants a spoken position in 60–90 seconds: the decision, the two facts that support it, one number from an exhibit, and what would change your mind. Structure beats completeness — instructors interrupt, and that's the exercise. If you're unsure, say what you do know and mark where the case stops answering; "the text doesn't say" is a respected answer in case classrooms, guessing silently is not.
A written assignment wants the full argument on paper: executive summary, problem statement, framework-based analysis grounded in exhibits, options weighed on named criteria, a committed recommendation, and references in your required style. Length comes from the rubric — commonly 1,000 to 2,500 words — and application marks come from exhibit numbers appearing in your prose. When citations are needed, the Harvard referencing generator formats the case study itself as a source in author–date style.
Pitfalls when reading (or writing about) teaching cases
- Hunting for the answer. There isn't one in the text. Students who "find" one have usually imported it from outside the case — and in class, that shows immediately.
- Skipping exhibits until "later". Later never comes. The narrative is written to withhold what exhibits reveal; a case without computed numbers is half-read.
- Summarising as analysis. "The company faced challenges and made decisions" is a book report. Analysis starts where the summary ends: why this choice, under these constraints, against these alternatives.
- Treating the protagonist as the analyst. The protagonist's view is data, not gospel. The board may be wrong; saying so — with evidence — is allowed and often rewarded.
- Missing the time stamp. Cases freeze a moment. Solutions that rely on technology or events after the case's date are anachronisms, and instructors spot them fast.
Anatomy quick quiz
1. A case ends mid-decision with no epilogue. Most likely reason?
Correct. The open ending is the teaching design: without a reveal, the analysis has to come from the room.
2. Where does a teaching case usually hide its hardest evidence?
Right. Narrative says; exhibits prove. The gap between the two is exactly where discussion questions come from.
3. The teaching note is described in class as "faculty's answer key". Accurate?
Correct. Teaching notes plan the discussion — assignment questions, board plan, anticipated positions. Students who treat them as answer keys misread the whole genre.
Want your written analysis of a teaching case checked?
If the assigned case is long and the write-up is due, a quoted, deadline-bound writer can draft the analysis — position, exhibits, alternatives, references — for you to make your own. Attach the case document and the rubric when you ask.
Frequently asked questions
Is this site affiliated with Harvard Business School?
No. CaseStudyWriting.com is an independent study-help site and is not affiliated with Harvard University or Harvard Business School. We don't sell, distribute or resell Harvard cases. This page describes the teaching-case format — a genre used by business schools everywhere — so you can read and analyse whatever cases your own course assigns.
How long is a typical teaching case?
Commonly somewhere between about 5 and 30 pages including exhibits — there's no fixed rule, and assignments vary widely. What's more useful than the page count is the reading plan: five passes as outlined above turn even a long case into roughly an hour of focused preparation.
Do I cite the case itself in my written analysis?
If your rubric asks for references, yes — cite the case as a published document (author or organisation, year, title, publisher) in the style your course requires. Our Harvard referencing generator handles author–date entries; check whether your tutor wants the case in the reference list, in-text only, or both.
What's the difference between this format and a normal business case study?
Mostly the openness. Academic case study papers report research with a conclusion; the teaching-case format ends unresolved on purpose and lives or dies by classroom debate. Structure, exhibits and the protagonist's dilemma are shared; the missing answer is the teaching case's signature.
Can I prepare for a case discussion without reading the full case?
You can pass, briefly. The first pass gets you the plot, and a skimmed position might survive one question — but exhibits decide the second and third. If time is genuinely gone, read the first and last pages plus every exhibit, compute one number, and commit to a modest position; honesty about what you skipped reads better than bluffing.
Where can I practise the format before my class uses one?
Any decision-forcing case works for practice, and sample material on our sample case study page shows the section-by-section structure with commentary. Apply the 5-pass plan to it, fill in the prep sheet, and the first real case in class will feel like a repeat rather than a debut.
