| Criterion |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Engineering Hypothesis-Driven Troubleshooting |
|---|---|---|
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. | When systems fail unexpectedly, spontaneous attempts often produce more noise than insight. Hypothesis-driven Troubleshooting translates symptoms into testable assumptions and makes troubleshooting learnable. |
Complexitydifferent | High | Medium |
Timedifferent | Several meetings plus preparation and analysis; total effort depends on scope | 30-240 min |
Participantsdifferent | Evaluation team, architects, and relevant stakeholders | 1-6 |
