Criterion	Product Discovery Learning Card	Decision Making Assumption Surfacing	Architecture ATAM (Architecture Tradeoff Analysis Method)	Product Discovery Assumption Mapping
Purposedifferent	The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible.	Plans often contain assumptions that were never openly stated and remain dangerous precisely because of that. Assumption Surfacing makes these silent premises visible and prioritizes which of them carry the initiative or could sink it.	ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation.	When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first.
