| Criterion |  Operations Change Analysis |  Agile Example Mapping |  Architecture SAAM (Software Architecture Analysis Method) |  Agile Three Amigos |
|---|---|---|---|---|
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 story carries business rules and exceptions, it brings clarity before implementation. It makes examples, open questions, and boundaries visible enough that the logic becomes jointly sound. | 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. | When story, test, and implementation could drift apart, it brings business perspective, engineering, and quality together early. It prevents a story from being read differently only late in the process. |
Complexitydifferent | Medium | Low | High | Low |
Timedifferent | 45-120 min | 30-60 min | Preparation, scenario analysis, and findings review; effort depends on scope | 15-30 min |
Participantsdifferent | 2-6 | 3-7 | Architecture experts and stakeholders for scenarios and weighting | 3 |
Formatdifferent | Workshop + async | Workshop | Workshop + async | Workshop + async |
Outputdifferent | Change Matrix, Cause Hypotheses, Validation Questions, Action List | Example Map, Acceptance Criteria, Open Questions | 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 | Clarified Story, Test Examples, Open Questions |
