| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Product Discovery Learning Card |  Agile Mad Sad Glad |  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. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. | When a team's or workshop's mood needs to become readable, it structures emotional signals with little setup. It makes strain, relief, and sources of energy tangible. | 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. |
