Selected:Architecture Decision Record Fault Isolation Argument Mapping ARID (Active Reviews for Intermediate Designs)

Criterion	Architecture Architecture Decision Record	Engineering Fault Isolation	Decision Making Argument Mapping	Architecture ARID (Active Reviews for Intermediate Designs)
Purposedifferent	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.	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.	When statements, evidence, and counterarguments get mixed up, a debate quickly loses its structure. Argument Mapping breaks a thesis down into its reasoning and makes visible what it really rests on.	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.
