Criterion	Product Discovery Assumption Mapping	Product Discovery Smoke Test	Architecture ARID (Active Reviews for Intermediate Designs)	Product Discovery Riskiest Assumption Test
Purposedifferent	When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first.	When demand only needs to be roughly verified, it tests interest with minimal effort. It measures whether people would take a next step at all.	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.	When an idea hinges on one critical unknown, it prioritizes testing that exact piece of uncertainty first. It separates problem, assumption, solution, and evidence. The result is captured as a prioritized list of assumptions, a test plan, and a result report.
