| Criterion |  Operations DMAIC |  Architecture SAAM (Software Architecture Analysis Method) |  Architecture C4 Model |
|---|---|---|---|
Purposedifferent | For a process problem with fluctuating performance, the method brings analysis and improvement into a disciplined sequence. It creates a framework in which numbers, causes, and control come together. | 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 C4 Model makes a system legible across several resolution levels, from context down to code. It suits situations where different audiences need to understand the same architecture from different altitudes. |
Complexitydifferent | High | High | Low |
Timedifferent | 2-12 Wochen | Preparation, scenario analysis, and findings review; effort depends on scope | 1-4 h |
Participantsdifferent | 3-10 | Architecture experts and stakeholders for scenarios and weighting | 1-5 |
