| Criterion |  Operations PDCA Cycle |  Operations Root Cause Analysis |  Architecture SAAM (Software Architecture Analysis Method) |
|---|---|---|---|
Purposedifferent | For an improvement that still has to prove itself in everyday work, the method runs it through small learning loops. It connects planning, checking, and standardization into a repeatable learning mode. | 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 | Low | Medium | High |
Timedifferent | 1 h bis mehrere Wochen | 1-4 h | Preparation, scenario analysis, and findings review; effort depends on scope |
