| Criterion |  Operations Change Analysis |  Operations Root Cause Analysis |  Architecture SAAM (Software Architecture Analysis Method) |
|---|---|---|---|
Purposedifferent | For a deviation after a change, the method isolates the influence of the altered condition. It narrows down which differences are relevant and which are just accompanying noise. | 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. | 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 | Medium | High |
Timedifferent | 45-120 min | 1-4 h | Preparation, scenario analysis, and findings review; effort depends on scope |
