| Criterion |  Systems Thinking CATWOE Analysis |  Systems Thinking Future Reality Tree |  Architecture SAAM (Software Architecture Analysis Method) |
|---|---|---|---|
Purposedifferent | CATWOE structures a problem from six viewpoints and prevents too narrow a view of the situation. Different experiences of the system become comparably discussable this way. | A Future Reality Tree shows how desired actions are meant to lead to a better system state. The method checks whether a path of change holds together logically before time flows into implementation. | 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 | High |
Timedifferent | 45-90 min | 2-4 h | Preparation, scenario analysis, and findings review; effort depends on scope |
Participantsdifferent | 3-8 | 3-8 | Architecture experts and stakeholders for scenarios and weighting |

Outputdifferent | CATWOE Canvas, Root Definition, Stakeholder Perspectives, Constraints | Future Reality Tree, Negative Branches, Assumption List, Improved Injections | 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 |
