Criterion	Product Discovery Opportunity Interview	Product Discovery Problem Interview	Architecture ARID (Active Reviews for Intermediate Designs)	Product Discovery Learning Card
Purposedifferent	When opportunities are still hidden behind signals of need, it structures conversations around needs and obstacles. It looks for patterns that lead to new product opportunities.	When the picture of the problem still needs to become solid, it asks about real situations and consequences. It separates genuine suffering from mere interest in a solution.	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.
