| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Product Discovery Assumption Mapping |  Agile 4Ls Retrospective |
|---|---|---|---|
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. | When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. | When a sprint should not only be assessed but also learned from, it captures experience in clear learning categories. It records what worked, what's missing, and what should run differently next time. |
Complexitydifferent | Medium | Medium | Low |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 45-60 min | 45–75 min |
