| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Architecture Views and Beyond |  Operations Change Analysis |  Architecture arc42 |
|---|---|---|---|---|
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. | Views and Beyond organizes architecture into several views so no single diagram has to do everything at once. This makes it possible to choose the representation that fits the stakeholder's question. | 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. | arc42 structures architecture knowledge so teams can document system, decisions, and risks consistently. The template builds a living understanding of the architecture instead of scattered notes. |
Complexitydifferent | High | Medium | Medium | Low |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 1-3 Tage | 45-120 min | 1-2 Tage |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1-4 | 2-6 | 1-4 |
