| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  UX Design Lean UX Canvas |  Architecture ATAM (Architecture Tradeoff Analysis Method) |
|---|---|---|---|
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 Lean UX Canvas helps clarify user behavior, touchpoints, and concept decisions. It makes assumptions and desired outcomes visible and captures the result as a completed canvas, hypothesis list, and first experiment. | 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. |
Complexitydifferent | High | Medium | High |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 2-3 h | Several meetings plus preparation and analysis; total effort depends on scope |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 3-8 | Evaluation team, architects, and relevant stakeholders |
Formatsame | Workshop + async | Workshop + async | Workshop + async |
