| Criterion |  Operations Change Analysis |  Operations Getting Things Done |  Architecture SAAM (Software Architecture Analysis Method) |  Operations ALPEN 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. | With many open commitments and ideas in daily life, a reliable external storage system emerges. The method relieves the mind so priority and context don't have to compete in memory. | 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. | With an overloaded day full of too many tasks, a realistic picture of the day emerges. The method connects estimating, deciding, and buffer thinking so planning fits available energy and time. |
Complexitydifferent | Medium | Medium | High | Low |
Timedifferent | 45-120 min | 1-2 h Setup, laufend | Preparation, scenario analysis, and findings review; effort depends on scope | 10-20 min daily |
