| Criterion |  Operations Failure Mode and Effects Analysis |  Architecture SAAM (Software Architecture Analysis Method) |  Operations Root Cause Analysis |
|---|---|---|---|
Purposedifferent | 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. | 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. | When a problem keeps recurring and the cause stays unclear, the method exposes the underlying mechanism. It separates symptom, guess, and robust explanation from one another. |
Complexitydifferent | High | High | Medium |
Timedifferent | 2-6 h | Preparation, scenario analysis, and findings review; effort depends on scope | 1-4 h |
