Selected:Goal Question Metric ARID (Active Reviews for Intermediate Designs)A/B Testing Counter Metrics

Criterion	Engineering Goal Question Metric	Architecture ARID (Active Reviews for Intermediate Designs)	Growth A/B Testing	Product Strategy Counter Metrics
Purposedifferent	Helps clarify technical problems, hypotheses, and next steps in concrete terms. It breaks a technical problem into testable parts. The result is captured as a GQM table and metric briefs.	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 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.	When a headline metric could mask side effects, it adds guardrail signals against unwanted outcomes. It connects customer value, product logic, and decision priorities. The result is captured as a counter-metric list and guardrail definitions.
