Criterion	Operations PDCA Cycle	Architecture ARID (Active Reviews for Intermediate Designs)	Product Discovery Hypothesis Prioritization Canvas	Product Discovery Learning Card
Purposedifferent	For an improvement that still has to prove itself in everyday work, the method runs it through small learning loops. It connects planning, checking, and standardization into a repeatable learning mode.	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 many hypotheses compete for attention, it brings order to their learning sequence and importance. It separates problem, assumption, solution, and evidence. The result is captured as a prioritization canvas and a hypothesis backlog.	The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible.
