Selected:A/B Testing ARID (Active Reviews for Intermediate Designs)Competency Questions Assumption Mapping

Criterion	Growth A/B Testing	Architecture ARID (Active Reviews for Intermediate Designs)	Knowledge Modeling Competency Questions	Product Discovery Assumption Mapping
Purposedifferent	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.	Competency Questions translate a domain model into concrete questions that it must be able to answer. The method keeps the model's scope clean and prevents pretty but useless structures.	When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first.
