Criterion	Architecture ARID (Active Reviews for Intermediate Designs)	Architecture Architecture Communication Canvas	Product Discovery Learning Card	Product Discovery Fake Door Test
Purposedifferent	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 Architecture Communication Canvas plans architecture communication so the right people receive the right message. The method turns technical complexity into deliberate communication design.	The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible.	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.
