Selected:arc42 Fault Isolation Architecture Inception Canvas ARID (Active Reviews for Intermediate Designs)

Criterion	Architecture arc42	Engineering Fault Isolation	Architecture Architecture Inception Canvas	Architecture ARID (Active Reviews for Intermediate Designs)
Purposedifferent	arc42 structures architecture knowledge so teams can document system, decisions, and risks consistently. The template builds a living understanding of the architecture instead of scattered notes.	In technical failures, the visible symptom often gets mixed up with the actual cause. Fault Isolation narrows the fault space and progressively reduces which part of the system is truly affected.	The Architecture Inception Canvas bundles the first architecture questions into a compact decision picture. It fits when an initiative is still in motion but still needs clear guardrails.	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.
