When a case feels unfamiliar, build the structure from the objective and the business logic in the prompt instead of searching your memory for a matching framework.

Unfamiliarity becomes a problem when you rely on pattern recognition. If you can break the objective into drivers, constraints, and decisions, you can still create a useful structure even when the industry or case type is new.

For a strange new business model, you could ask what creates demand, what drives revenue and cost, whether the client can execute, and what risks could change the decision.

Practice with prompts you have not seen and force yourself to structure them before reading any solution. Focus on whether each branch helps answer the objective. For a step-by-step guide, see Case Structure vs. Case Framework.

Unfamiliar industries used to throw me off more than unfamiliar case types. Going back to the objective helped.

I started asking myself "what has to be true for this to work?" and my structures got much less template-y.

same here. Random prompt drills helped me more than memorizing another framework.
