|---|---|---|---|---|
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. | With a restless workday full of too many open items, the method creates radical simplicity. It directs attention to a short sequence instead of a broad, still-open field. | When a project faces many possible disruptions, it quickly becomes unclear which risks deserve attention first. It separates options, evaluation criteria, and open risks. The result is captured as a Risk Matrix and a Top Risk List. | Plans often contain assumptions that were never openly stated and remain dangerous precisely because of that. Assumption Surfacing makes these silent premises visible and prioritizes which of them carry the initiative or could sink it. |
Complexitydifferent | High | Low | Low | Low |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 5-10 min daily | 30-60 min | 45-90 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1 | 3-10 | 2-8 |
Formatdifferent | Workshop + async | 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 | Daily Priority List, Completion Notes | Risk Matrix, Top Risk List | Assumption List, Critical Assumptions, Learning Plan |
