|---|---|---|---|---|
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. | 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. | arc42 structures architecture knowledge so teams can document system, decisions, and risks consistently. The template builds a living understanding of the architecture instead of scattered notes. | An ADR permanently records an architecture decision with context, trade-offs, and consequence. It creates continuity for later changes because the decision path stays traceable. |
Complexitydifferent | High | Low | Low | Low |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 45-90 min | 1-2 Tage | 15-45 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 2-8 | 1-4 | 1-3 |
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 | Assumption List, Critical Assumptions, Learning Plan | Architecture Document, Context View, Runtime View, Deployment View | ADR File, Decision Log, Rationale |
