| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Operations Root Cause Analysis |  Operations MORT Analysis |
|---|---|---|---|
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 problem keeps recurring and the cause stays unclear, the method exposes the underlying mechanism. It separates symptom, guess, and robust explanation from one another. | 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 | 2–4 h review as a planning range; preparation and evaluation additional | 1-4 h | Mehrere Tage bis Wochen |
Participantsdifferent | Designers, developers as users, and facilitation | 3-8 | 2-6 |
