| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Agile 4Ls Retrospective |  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. | 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. | 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. |
