| Criterion |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Growth North Star Metric |
|---|---|---|
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 product teams track many metrics, the view of the actual customer outcome easily gets lost. A North Star Metric bundles growth, usage, and value contribution into one signal that makes the system's direction visible. |
Complexitydifferent | High | Medium |
Timedifferent | Several meetings plus preparation and analysis; total effort depends on scope | 1-2 h |
Participantsdifferent | Evaluation team, architects, and relevant stakeholders | 3-8 |
