Selected:Affinity Diagramming Architecture Decision Record A/B Testing ARID (Active Reviews for Intermediate Designs)

Criterion	UX Research Affinity Diagramming	Architecture Architecture Decision Record	Growth A/B Testing	Architecture ARID (Active Reviews for Intermediate Designs)
Purposedifferent	When research notes, feedback, or observations sit unconnected side by side, affinity diagramming sorts the raw material into solid themes. Many individual points turn into patterns that make decisions and opportunities clearer.	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.	When two variants compete, discussions quickly decide by taste rather than effect. A/B Testing checks behavior under controlled conditions and separates real improvement from chance or expectation effects.	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.
