| Criterion |  Decision Making PERT Estimation |  Architecture SAAM (Software Architecture Analysis Method) |
|---|---|---|
Purposedifferent | On complex initiatives, a plain average tends to understate just how uncertain the outcome really is. It separates options, evaluation criteria, and open risks. The result is captured as a PERT Estimate, Expected Value, and Risk Notes. | 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. |
Complexitydifferent | Medium | High |
Timedifferent | 15-45 min | Preparation, scenario analysis, and findings review; effort depends on scope |
Participantsdifferent | 1-8 | Architecture experts and stakeholders for scenarios and weighting |
