Criterion	Decision Making Decision Matrix	Architecture ARID (Active Reviews for Intermediate Designs)	Product Discovery Learning Card	Product Discovery Experiment Canvas
Purposedifferent	When several options collide with several criteria, comparison quickly becomes subjective. A Decision Matrix makes the trade-off visible and brings weighting, criteria, and options into a shared logic.	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 experiments become unreadable after the fact, it arranges hypothesis, signal, and learning goal on a single canvas. It separates problem, assumption, solution, and evidence. The result is captured as a Completed Experiment Canvas and a Success Metric.
