| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Systems Thinking VUCA Scan |  Architecture C4 Model |
|---|---|---|---|
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 VUCA Scan helps read difficult situations more precisely. Instead of treating unclarity as generally complicated, the method separates fast change, missing knowledge, systemic entanglement, and ambiguous interpretation. | 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 | Low | Low |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 30-90 min | 1-4 h |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1-10 | 1-5 |
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 | VUCA Map, Response Options, Signal and Learning Plan | Context Diagram, Container Diagram, Component Diagram |
