| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Product Discovery Learning Card |  DevOps Blameless Postmortem |
|---|---|---|---|
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. | After an incident with damage or a near miss, the method creates a sober field for learning without assigning blame. It directs attention to the course of events, conditions, and effective countermeasures. |
Complexitydifferent | Medium | Low | Medium |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 25-40 min | 30-90 min |
Participantsdifferent | Designers, developers as users, and facilitation | 1-5 | 3-12 |
