|---|---|---|---|---|
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 many hypotheses compete for attention, it brings order to their learning sequence and importance. It separates problem, assumption, solution, and evidence. The result is captured as a prioritization canvas and a hypothesis backlog. | For a deviation after a change, the method isolates the influence of the altered condition. It narrows down which differences are relevant and which are just accompanying noise. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. |
Complexitydifferent | High | Medium | Medium | Low |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 60-90 min | 45-120 min | 20-35 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 3-8 | 2-6 | 1-5 |
Formatdifferent | Workshop + async | Workshop | 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 | Prioritization Canvas, Hypothesis Backlog | Change Matrix, Cause Hypotheses, Validation Questions, Action List | Test Card with a pre-set threshold |
