| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Product Strategy Impact Mapping |  Engineering Goal Question Metric |
|---|---|---|---|
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 a goal needs to be connected to several possible paths, it shows chains of impact instead of feature lists. It connects business goal, behavior change, and measures. | Helps clarify technical problems, hypotheses, and next steps in concrete terms. It breaks a technical problem into testable parts. The result is captured as a GQM table and metric briefs. |
Complexitydifferent | High | Medium | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 45-90 min | 90-180 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 3-8 | 3-6 |
Formatdifferent | Workshop + async | Workshop | Workshop |
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 | Impact Map, Outcome Hypotheses, Delivery Options | GQM Table, Metric Profiles |
