|---|---|---|---|
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. | 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. | When a problem keeps recurring and the cause stays unclear, the method exposes the underlying mechanism. It separates symptom, guess, and robust explanation from one another. |
Complexitydifferent | High | Low | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 15-45 min | 1-4 h |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 2-8 | 3-8 |
