Case Studies / Topic guide

How to read a business case study critically

Separate the stated result from the evidence, the context and the choices that shaped it.

Begin by identifying the question the case is trying to answer. A story about rapid growth may say little about profit, customer retention or the resources required. Look for a clear definition of the outcome.

Examine the starting conditions and constraints. Timing, access to capital, distribution and an existing reputation can influence the result. A useful case explains these conditions rather than presenting a decision as universally effective.

Ask which alternatives were available and why one was selected. Note the evidence behind the explanation and whether competing interpretations are considered. Treat missing information as a limitation, not an invitation to fill the gap with assumptions.

Translate a case into a question for your own situation rather than copying the tactic. Identify what would need to be true for the approach to work. This starter guide explains how to assess cases; it does not claim to be original company reporting.
