|---|---|---|---|---|
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. | Concept Mapping arranges terms and relationships in a network that makes subject-matter connections tangible. It fits when a topic needs to be understood structurally rather than linearly. | When a problem has several possible contributing factors, the method sorts causes by cause areas. It prevents an initial hunch from blocking the view of other plausible drivers. | 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 | Medium | Low | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 1-2 h | 30-60 min | 45-120 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1-8 | 2-8 | 2-6 |
Formatdifferent | Workshop + async | 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 | Concept Map, Relationship Labels, Knowledge Gaps | Fishbone Diagram, Cause Categories, Investigation Backlog | Change Matrix, Cause Hypotheses, Validation Questions, Action List |
