|---|---|---|---|---|
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. | LASR helps development teams identify where their software falls short of important quality goals and which improvements to consider. A small group with existing system knowledge can make an initial assessment and investigate open questions in more detail. | In cross-functional decisions, responsibilities quickly blur between approval, influence, and execution. DACI arranges these roles so decision pressure, contribution, and information stay cleanly separated. |
Complexitydifferent | High | Medium | Medium | Low |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 45-90 min | 3–4 h for initial assessment; preparation and deeper analysis additional | 30-60 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 3-12 | 1 or a small team; particularly suitable for 3–4 people | 2-10 |
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 | RAPID Role Map, Recommendation, Decision Log | Lean Mission Statement describing the software’s purpose, Prioritized quality goals and evaluation criteria, Risks and estimated gaps against quality goals, More closely examined findings and open checks | DACI Matrix, Decision Owner, Decision Log |
