|---|---|---|---|
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 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. | When three perspectives matter at the same time, a Three-Circle Venn Diagram shows the overlaps and remainders precisely. It makes visible where shared effect arises and where only a partial perspective applies. |
Complexitydifferent | High | Medium | Low |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 45-120 min | 15-45 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 2-6 | 2-8 |
Formatsame | Workshop + async | Workshop + async | 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 | Change Matrix, Cause Hypotheses, Validation Questions, Action List | Venn Diagram, Overlap Notes, Differentiators |
