| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Product Discovery Test Card |  Product Discovery Assumption Mapping |
|---|---|---|---|
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. | When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. |
Complexitydifferent | High | Low | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 20-35 min | 45-60 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1-5 | 2-8 |
Formatsame | 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 | Test Card with a pre-set threshold | Assumption map, Test backlog, Risk ranking |
