Criterion	Architecture ARID (Active Reviews for Intermediate Designs)	Product Discovery Outcome-Driven Innovation	Product Discovery Opportunity Solution Tree	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.	Outcome-Driven Innovation clarifies customer problems, solution opportunities, and evidence. It separates jobs, desired outcomes, importance, satisfaction, and opportunity, and captures results as desired outcome statements, an opportunity landscape, and segments by underserved needs.	When discovery keeps swinging between goals, ideas, and learning loops, it creates clear steering logic. It connects the desired outcome, opportunities, and experiments into a legible structure.	The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible.
