| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Operations A3 Problem Solving |  Architecture arc42 |
|---|---|---|---|
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. | For a complex deviation with several people involved, the method bundles problem, analysis, and decision onto one page. It creates a shared working space where causes, countermeasures, and follow-up fit together. | 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. |
Complexitydifferent | High | Medium | Low |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 45-90 min | 1-2 Tage |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 2-5 | 1-4 |
Formatsame | Workshop + async | Workshop + async | Workshop + 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 | A3 Report, Action Plan, Root Cause Analysis | Architecture Document, Context View, Runtime View, Deployment View |
