| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Decision Making Force Field Analysis |  Facilitation 3-Circle Venn Diagram |
|---|---|---|---|
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. | In change initiatives, supporting and restraining forces sit at the table at the same time. Force Field Analysis makes these tensions explicit and shows where change can be pushed forward by strengthening or relieving. | When three perspectives matter at the same time, a Three-Circle Venn Diagram shows the overlaps and remainders precisely. It makes visible where shared effect arises and where only a partial perspective applies. |
Complexitydifferent | High | Low | Low |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 45-90 min | 15-45 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 3-12 | 2-8 |
Formatdifferent | Workshop + async | Workshop | 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 | Force Field Map, Change Levers, Risk Notes | Venn Diagram, Overlap Notes, Differentiators |
