| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Architecture arc42 |  Operations Getting Things Done |  Operations ALPEN Method |
|---|---|---|---|---|
Purposedifferent | 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. | arc42 structures architecture knowledge so teams can document system, decisions, and risks consistently. The template builds a living understanding of the architecture instead of scattered notes. | 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. | 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 | High | Low | Medium | Low |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 1-2 Tage | 1-2 h Setup, laufend | 10-20 min daily |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1-4 | 1 | 1 |
Formatdifferent | Workshop + async | Workshop + async | Async | Async |
Outputdifferent | Domain functions mapped to components and connections, Quality attributes and evaluation criteria, Typical tasks and their effects on the architecture, Reasoned evaluation or comparison of alternatives | Architecture Document, Context View, Runtime View, Deployment View | Action Lists, Project List, Review Routine | Daily Plan, Time Estimates, Review Notes |
