|---|---|---|---|---|
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. | In complex management decisions, clarity is often missing about who recommends, who agrees, and who makes the decision. RAPID creates this assignment and stabilizes decisions across several levels. | For an acute quality or delivery problem, the method structures immediate protection and root cause work together. It keeps the situation stable while the actual cause is investigated cleanly. | An RFC clarifies architecture context, options, and consequences. It structures technical context, alternatives, tradeoffs, open questions, and review feedback, and captures the result as an RFC document, reviewer comments, and a decision rationale. |
Complexitydifferent | High | Medium | High | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 45-90 min | 1-6 Wochen | 1-3 Wochen vom Draft bis zur Entscheidung |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 3-12 | 4-10 | 3-20 Reviewer |
Formatdifferent | Workshop + async | Workshop + async | Workshop + async | 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 | RAPID Role Map, Recommendation, Decision Log | 8D Report, Containment Plan, Root Cause Evidence, Corrective Action Plan | RFC document, Reviewer comments, Decision rationale, Follow-up ADR or tickets |
