| Criterion |  Engineering Goal Question Metric |  Architecture ATAM (Architecture Tradeoff Analysis Method) |
|---|---|---|
Purposedifferent | Helps clarify technical problems, hypotheses, and next steps in concrete terms. It breaks a technical problem into testable parts. The result is captured as a GQM table and metric briefs. | 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. |
Complexitydifferent | Medium | High |
Timedifferent | 90-180 min | Several meetings plus preparation and analysis; total effort depends on scope |
