How to Prepare for Business Case Studies Before Class

Why preparation decides the discussion grade

Case-method courses grade what happens in the room. The professor opens with a question, a classmate answers, and suddenly the discussion is three decisions deep with you still finding the page. Preparation is what lets you join at that speed — and in courses built on the case discussion method, cold calls are a normal tool, not an ambush. Being ready for them is part of the assignment.

The good news: you do not need to memorise the case. You need three things when you walk in — the core problem in one sentence, three pieces of evidence for your view, and one honest weakness in your own argument you can concede before someone else finds it. Everything in this guide builds toward those three.

Preparation matters most when the questions start arriving unscripted. The case study interview questions drill rehearses the six question types against a 90-second timer, with a model answer outline behind every card.

The 3-pass reading method

Reading a business case start to finish at one speed is the slowest useful way to do it. Three passes, each with one job, get you ready in far less time:

Most students discover pass 2 shrinks once pass 1 tells them what to hunt for. A 12-page case plus exhibits usually needs one focused evening hour, not a lost weekend — and the drill planner below scales the passes to whatever time you actually have left.

The issue tree: notes that survive a cold call

Linear notes — one bullet after another — are hard to read under pressure. An issue tree organises the same facts by question instead. At the top sits the decision the case forces; on the second level sit the two or four issues that decide it; on the third, the evidence from the case for each side. That tree is also the fastest way to decode a Harvard Business School case study assignment — the decision node at the top is exactly the dilemma the case ends on.

DECISION: Should the chain close the two losing city stores?
|-- Issue A: Is the loss structural or temporary?
|     |-- for closing: rent up 40% since the lease was signed (exhibit 2)
|     |-- against: footfall recovering since the metro opened (p. 9)
|-- Issue B: What does closing cost us elsewhere?
|     |-- brand impact: city stores feed the delivery app (p. 11)
|     |-- exit costs: staff, leases, contract penalties (exhibit 5)
|-- MY CALL: renegotiate one lease, close the other, keep delivery

Under pressure you read down one branch instead of scanning a page of prose. Keep the whole tree to a single page — if it spills over, you are collecting facts instead of building an argument. This same structure converts directly into the problem statement section if the course also asks for a written case study paper.

Timed drill planner

Enter your time and the case length; the planner splits the minutes across the three passes plus a quick-write, and hands you a schedule you can start immediately.

Short on time? Protect pass 2 and the quick-write first. A thin skim plus a sharp position beats a slow full read with no position at all.

Build a position the evidence can carry

"I think the company should expand" is an opinion. A position has four parts: the claim ("I would enter through a licensing partner"), the evidence (three case facts, with exhibit numbers), the reasoning (what connects the facts to the claim), and the concession (the strongest objection and your answer). Practice writing all four in five sentences before class.

Why bother with the concession? Because case discussions reward people who can hold a view and update it. If you have already named your argument's weak point, a challenge from the professor lands as confirmation you thought it through, not as a hole in your prep. And if someone raises a different objection, you say the magic sentence: "I hadn't considered that — my current thinking is X, and that would change my call if…" That sentence, said once per class, buys you more credit than five more opinions.

The preparation checklist

Run this the night before. Tick as you go.

• Read the assignment questions first, then the case — questions tell you what to hunt for.
• Finished pass 1 and can say what decision the case is about, in one sentence.
• Pass 2 marks include exhibit numbers next to every fact I plan to cite.
• My position sentence is written: problem, decision, because-clause.
• I named the strongest objection to my own position and my answer to it.
• I have one comment that builds on the likely majority view, in case the obvious ground is taken.
• One framework question is ready to ask the class (a good question earns the same credit as a good answer).
• My issue tree fits one page and I have reread it once, out loud, the morning of class.

"What if the professor calls on me?" — six scripted situations

Flip each card. The front is the situation; the back is the move. These work because they all follow one rule: reason aloud from the case instead of performing certainty. And if your program goes one step further and grades a formal case interview — a longer, scored version of the cold call — the case study interview page walks through that format and how preparation shifts when the clock itself is being judged.

Discussing without dominating

Participation grades reward quality, and the fastest way to look strong is to make others look heard. Three habits do most of the work: restate before you rebut, cite one exhibit per contribution, and stop after your two best points per class. If a discussion is racing somewhere useful, a short "can we pin that down — is that a cause or a symptom?" is worth as much as a new argument. The goal is to be the person whose comments get quoted later in the class, not the person who filled the most minutes.

Prepared properly, the case discussion is also the cheapest analysis practice you will get — the same fact → problem → cause → recommendation chain that the written business case study analysis demands, just out loud. Students who speak in structure write in structure.
