|---|---|---|---|---|
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 discovery keeps swinging between goals, ideas, and learning loops, it creates clear steering logic. It connects the desired outcome, opportunities, and experiments into a legible structure. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | 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. |
Complexitydifferent | High | Medium | Low | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 1-2 h Setup, laufend | 20-35 min | 2-3 h |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 2-6 | 1-5 | 3-8 |
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 | Opportunity Solution Tree, Experiment Backlog, Learning Log | Test Card with a pre-set threshold | Completed Lean UX Canvas, Hypothesis list, First experiment |
