| Criterion |  Decision Making Risk Matrix |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Product Discovery Test Card |
|---|---|---|---|
Purposedifferent | When a project faces many possible disruptions, it quickly becomes unclear which risks deserve attention first. It separates options, evaluation criteria, and open risks. The result is captured as a Risk Matrix and a Top Risk List. | 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. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. |
