Criterion	Systems Thinking Evaporating Cloud	Product Discovery Assumption Mapping	Architecture ARID (Active Reviews for Intermediate Designs)	Decision Making Assumption Surfacing
Purposedifferent	The method makes visible why two seemingly incompatible demands arise and which assumption must be tested to resolve the conflict.	When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first.	ARID examines how well developers can work with a technical design. It focuses on a part of the system that can still be revised, between the architecture overview and the detailed specification.	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.
