| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Engineering Fault Isolation |  Business Strategy Business Model Stress Test |
|---|---|---|---|
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. | In technical failures, the visible symptom often gets mixed up with the actual cause. Fault Isolation narrows the fault space and progressively reduces which part of the system is truly affected. | A Business Model Stress Test checks how well a business model holds up under pressure and headwinds. It compares strengths, risks, market logic, and courses of action. The result is captured as a stress-test report and action plan per scenario. |
Complexitydifferent | High | Medium | High |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 30-180 min | Half day |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1-6 | 3-8 |
Formatdifferent | Workshop + async | Workshop + async | Workshop |
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 | Fault Isolation Map, Test Log, Excluded Hypotheses, Narrowed Fault Area | Stress Test Report, Action Plan per Scenario |
