| Criterion |  DevOps Blameless Postmortem |  Architecture ARID (Active Reviews for Intermediate Designs) |  Architecture ATAM (Architecture Tradeoff Analysis Method) |
|---|---|---|---|
Purposedifferent | 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. | 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. | ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation. |
Complexitydifferent | Medium | Medium | High |
Timedifferent | 30-90 min | 2–4 h review as a planning range; preparation and evaluation additional | Several meetings plus preparation and analysis; total effort depends on scope |
