| Criterion |  Knowledge Modeling IBIS |  Architecture SAAM (Software Architecture Analysis Method) |  Operations Failure Mode and Effects Analysis |
|---|---|---|---|
Purposedifferent | IBIS structures thinking about complex questions as a sequence of issues, ideas, and arguments. The method keeps discussions open without forcing them into premature consensus. | 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. | For a process, product, or service with noticeable failure risks, the method assesses possible failure modes in advance. It directs attention to combinations of occurrence, effect, and detectability. |
Complexitydifferent | Medium | High | High |
Timedifferent | 1-3 h | Preparation, scenario analysis, and findings review; effort depends on scope | 2-6 h |
