Criterion	Architecture ARID (Active Reviews for Intermediate Designs)	Product Discovery Fake Door Test	Facilitation Problem Framing Workshop	Product Discovery Learning Card
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.	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.	When a team works on symptoms but the real question stays fuzzy, a Problem Framing Workshop sharpens the view of the right problem. It separates observation, interpretation, and target picture from each other.	The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible.
