| Criterion |  Agile ROAM Board |  Architecture ARID (Active Reviews for Intermediate Designs) |  Growth A/B Testing |
|---|---|---|---|
Purposedifferent | When work needs to move between different states or columns, it makes that movement and its handoffs legible. It sorts work by value, risk, and delivery ability. The result is captured as a ROAM Board and an Owner List. | 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. |
Complexitydifferent | Low | Medium | High |
Timedifferent | 20-40 min initial, dann laufend | 2–4 h review as a planning range; preparation and evaluation additional | 1-4 Wochen |
