|---|---|---|---|---|
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 ideas need sorting quickly, it condenses impact, confidence, and effort into one compact score. It connects customer value, product logic, and decision priorities. The result is captured as an ICE table and top-ideas list. | 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. | 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 | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 30-60 min | 1-4 h | 45-120 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 2-8 | 3-8 | 2-6 |
Formatsame | Workshop + async | 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 | ICE Table, Top Idea List | Problem Statement, Cause Hypotheses, Confirmed Causes, Action Plan | Change Matrix, Cause Hypotheses, Validation Questions, Action List |
