| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Engineering Fault Isolation |  Operations 8D Problem Solving |
|---|---|---|---|
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. | For an acute quality or delivery problem, the method structures immediate protection and root cause work together. It keeps the situation stable while the actual cause is investigated cleanly. |
Complexitydifferent | High | Medium | High |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 30-180 min | 1-6 Wochen |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1-6 | 4-10 |
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 | Fault Isolation Map, Test Log, Excluded Hypotheses, Narrowed Fault Area | 8D Report, Containment Plan, Root Cause Evidence, Corrective Action Plan |
