Criterion	Product Discovery Fake Door Test	Architecture ARID (Active Reviews for Intermediate Designs)	Product Discovery Learning Card	Product Discovery Riskiest Assumption Test
Purposedifferent	When demand is still unclear, it measures interest in a feature before it is built. It separates real behavior from polite agreement and deliberately keeps build effort small.	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.	The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible.	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.
