|---|---|---|---|---|
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. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation. | When experiments become unreadable after the fact, it arranges hypothesis, signal, and learning goal on a single canvas. It separates problem, assumption, solution, and evidence. The result is captured as a Completed Experiment Canvas and a Success Metric. |
Complexitydifferent | High | Low | High | Low |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 20-35 min | Several meetings plus preparation and analysis; total effort depends on scope | 30-60 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1-5 | Evaluation team, architects, and relevant stakeholders | 1-5 |
Formatsame | Workshop + async | Workshop + async | Workshop + async | Workshop + async |
