| Criterion |  DevOps Incident Timeline Analysis |  Architecture ARID (Active Reviews for Intermediate Designs) |  Operations MORT Analysis |
|---|---|---|---|
Purposedifferent | For an incident with an unclear sequence, the method makes the timeline precisely visible. It separates perception, reaction, and delay so cause and effect become more clearly readable. | 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. | For a safety-relevant event or a system with high protection requirements, the method examines where controls failed. It exposes both technical and organizational gaps. |
Complexitydifferent | Medium | Medium | High |
Timedifferent | 60-180 min | 2–4 h review as a planning range; preparation and evaluation additional | Mehrere Tage bis Wochen |
