Hi everyone,
I’ve been going through various resources on profitability cases (e.g. Victor Cheng’s Case Interview Secrets, videos, etc.) and I still have a question about the very beginning of a classic case where you would use the typicall Revenue-Cost framework or at least some variation of it:
When opening a profitability case, is it generally better to:
- Start with the framework (profit = revenue – costs, and then drill down into the sub-branches), stating that declining profits must come from one or both sides?
OR
- First ask some clarifying, business-specific questions (e.g. product mix, distribution channels, regions of operation, etc.) to better understand the context before committing to a tree? For example, if I clarify early that the client only operates domestically and sources all inputs locally, I would already know that tariffs or FX fluctuations are unlikely drivers and can focus my analysis more effectively.
Do you recommend always laying out the revenue-cost framework first and then adapting, or is it smarter to tailor the structure upfront with more contextual questions?
Thanks in advance for your thoughts!
