| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Operations Barrier Analysis |  Architecture SAAM (Software Architecture Analysis Method) |  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. | For a risk that can only be managed through multiple layers of protection, the method examines the effectiveness of each barrier. It shows where safeguards are missing, too weak, or fail under real conditions. | SAAM helps teams judge an architecture’s suitability for selected tasks and changes. It is particularly useful for examining modifiability and comparing architecture alternatives with clear reasoning. | 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 | High |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 2-4 h | Preparation, scenario analysis, and findings review; effort depends on scope | Mehrere Tage bis Wochen |
Participantsdifferent | Designers, developers as users, and facilitation | 2-6 | Architecture experts and stakeholders for scenarios and weighting | 2-6 |
Formatsame | Workshop + async | Workshop + async | Workshop + async | Workshop + async |
Outputdifferent | Prioritized development tasks, Jointly produced code or pseudocode, Observed difficulties and open design questions, Proposed design revisions | Barrier Inventory, Failure Analysis per Barrier, Action Backlog | Domain functions mapped to components and connections, Quality attributes and evaluation criteria, Typical tasks and their effects on the architecture, Reasoned evaluation or comparison of alternatives | MORT Worksheets, Findings per Branch, Corrective Actions, Systemic Recommendations |
