Case method

The case method is a classroom form that teaches from a written business situation instead of a chapter of theory first. Students read a packet — company facts, exhibits, a decision — and then spend the session arguing what the protagonist should do.

Harvard Business School popularized the form for management education. Plenty of MBA programs use it for some courses and lectures for others. The method is a pedagogy, not a brand license. A school can run cases without being HBS.

How it works

Preparation is the work. A 15- to 30-page case with exhibits takes two or three hours if the student builds a position, not a summary. Learning teams often meet the night before to pressure-test the numbers. In class, the instructor opens with a question and moves around the room. A cold call starts the hour by naming a student who did not raise a hand.

Grades in a pure case course lean on participation plus a few write-ups or an exam case. That makes attendance and talking quality load-bearing in a way a lecture course does not. Quiet competence does not show up on the roster.

Example: a first-year strategy case gives a retailer three options — raise price, cut SKUs, or sell a division — and an exhibit with two years of margins. The instructor cold-calls a student at minute one: “What would you do?” The useful answer names a decision, a number from the exhibit, and a risk. “It depends” without a pick wastes the next ten minutes and scores as a miss.

How it differs

The lecture method transmits a model, then assigns problems. Cases invert that: the decision comes first, the model is pulled in as needed. A case competition is a timed team event with judges, not a term-long class. Simulations put students inside a model they can click; cases put them inside a static packet.

Common errors

Summarizing the story instead of taking a position. Outsourcing exhibit work to one teammate and then freezing on a cold call. Treating “participation” as raw airtime. Reading every case as if there were a published right answer in the teaching note — there is a teaching note, and students do not get it.
