| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Architecture Request for Comments |  Growth A/B Testing |  Product Discovery Smoke Test |
|---|---|---|---|---|
Purposedifferent | 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. | An RFC clarifies architecture context, options, and consequences. It structures technical context, alternatives, tradeoffs, open questions, and review feedback, and captures the result as an RFC document, reviewer comments, and a decision rationale. | 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 demand only needs to be roughly verified, it tests interest with minimal effort. It measures whether people would take a next step at all. |
Complexitydifferent | Medium | Medium | High | Low |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 1-3 Wochen vom Draft bis zur Entscheidung | 1-4 Wochen | 1-5 Tage |
Participantsdifferent | Designers, developers as users, and facilitation | 3-20 Reviewer | 1-6 | Nutzertraffic |
Formatdifferent | Workshop + async | Async | Async | Async |
Outputdifferent | Prioritized development tasks, Jointly produced code or pseudocode, Observed difficulties and open design questions, Proposed design revisions | RFC document, Reviewer comments, Decision rationale, Follow-up ADR or tickets | Experiment results, Decision log, Learning summary | Interest Metrics, Conversion Signal, Learning Note |
