| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Operations MORT Analysis |  Operations Root Cause Tree Analysis |
|---|---|---|---|
Purposedifferent | 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. | For a problem with several suspected causes, the method builds a causal structure instead of a mere list. It makes visible how causes connect and where the strongest points of leverage lie. |
Complexitydifferent | High | High | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | Mehrere Tage bis Wochen | 1-3 h |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 2-6 | 2-8 |
Formatdifferent | Workshop + async | Workshop + async | Workshop |
Outputdifferent | 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 | Cause Tree, Evidence Notes, Countermeasures |
