| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Architecture LASR (Lightweight Approach for Software Reviews) |  Product Discovery Smoke Test |  Growth A/B Testing |
|---|---|---|---|---|
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. | LASR helps development teams identify where their software falls short of important quality goals and which improvements to consider. A small group with existing system knowledge can make an initial assessment and investigate open questions in more detail. | 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. | 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. |
Complexitydifferent | Medium | Medium | Low | High |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-5 Tage | 1-4 Wochen |
Participantsdifferent | Designers, developers as users, and facilitation | 1 or a small team; particularly suitable for 3–4 people | Nutzertraffic | 1-6 |
Formatdifferent | Workshop + async | Workshop + async | Async | Async |
Outputdifferent | Prioritized development tasks, Jointly produced code or pseudocode, Observed difficulties and open design questions, Proposed design revisions | Lean Mission Statement describing the software’s purpose, Prioritized quality goals and evaluation criteria, Risks and estimated gaps against quality goals, More closely examined findings and open checks | Interest Metrics, Conversion Signal, Learning Note | Experiment results, Decision log, Learning summary |
