| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Operations Failure Mode and Effects Analysis |  Operations Root Cause Analysis |
|---|---|---|---|
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 process, product, or service with noticeable failure risks, the method assesses possible failure modes in advance. It directs attention to combinations of occurrence, effect, and detectability. | When a problem keeps recurring and the cause stays unclear, the method exposes the underlying mechanism. It separates symptom, guess, and robust explanation from one another. |
Complexitydifferent | High | High | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 2-6 h | 1-4 h |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 3-10 | 3-8 |
Formatdifferent | Workshop + async | Workshop | 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 | FMEA Table, Risk Priority, Mitigation Actions | Problem Statement, Cause Hypotheses, Confirmed Causes, Action Plan |
