| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Operations MORT Analysis |  Systems Thinking Stock and Flow Diagram |
|---|---|---|---|
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. | 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. | A Stock and Flow Diagram shows how stocks, inflows, and outflows shape a system over time. It is especially suited when growth, delays, or capacity limits determine the dynamics. |
Complexitydifferent | Medium | High | High |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | Mehrere Tage bis Wochen | 2-6 h |
Participantsdifferent | Designers, developers as users, and facilitation | 2-6 | 1-6 |
