| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Decision Making Pre-Mortem |  Operations Change 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. | In early initiatives with many uncertainties, planning quickly turns too optimistic. A pre-mortem makes the expected failure visible in advance and sharpens the view of causes, gaps, and countermeasures. | For a deviation after a change, the method isolates the influence of the altered condition. It narrows down which differences are relevant and which are just accompanying noise. |
Complexitydifferent | High | Low | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 20–45 min | 45-120 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | Small cross-functional group | 2-6 |
Formatdifferent | Workshop + async | Workshop | Workshop + async |
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 | Risk list, Mitigation plan, Assumption log | Change Matrix, Cause Hypotheses, Validation Questions, Action List |
