Selected:Problem Interview Architecture Decision Record ARID (Active Reviews for Intermediate Designs)Concierge MVP

Criterion	Product Discovery Problem Interview	Architecture Architecture Decision Record	Architecture ARID (Active Reviews for Intermediate Designs)	Product Discovery Concierge MVP
Purposedifferent	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.	An ADR permanently records an architecture decision with context, trade-offs, and consequence. It creates continuity for later changes because the decision path stays traceable.	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 an idea can first fail or grow through genuine hands-on support, it relies on manual work instead of automation. It shows whether user value holds up even under manual execution.
