|---|---|---|---|---|
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 knowledge is distributed and direct dominance should be avoided, groups quickly fall under the sway of their opinion leaders. The Delphi Method gathers assessments iteratively and gradually brings expert judgments closer together. | For a disturbance that's hard to pin down, the method cleanly separates problem, cause, and decision. It reduces mixing when symptoms allow several interpretations. | 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 | High | High | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 1-4 Wochen | 2-8 h | 45-120 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 6-30 Experten | 2-8 | 2-6 |
Formatdifferent | Workshop + async | Async | Workshop + async | Workshop + async |
