| Criterion |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Knowledge Modeling Concept Mapping |  Operations Root Cause Analysis |
|---|---|---|---|
Purposedifferent | ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation. | Concept Mapping arranges terms and relationships in a network that makes subject-matter connections tangible. It fits when a topic needs to be understood structurally rather than linearly. | 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 | Medium | Medium |
Timedifferent | Several meetings plus preparation and analysis; total effort depends on scope | 1-2 h | 1-4 h |
Participantsdifferent | Evaluation team, architects, and relevant stakeholders | 1-8 | 3-8 |
