| Criterion |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Decision Making Risk Matrix |  Delivery Cost of Delay |
|---|---|---|---|
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 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. | Helps clarify scope, order, and delivery flow in concrete terms. It makes work, constraints, and sequence manageable. The result is captured as a Cost of Delay table and prioritization sequence. |
Complexitydifferent | High | Low | High |
Timedifferent | Several meetings plus preparation and analysis; total effort depends on scope | 30-60 min | 90-180 min |
Participantsdifferent | Evaluation team, architects, and relevant stakeholders | 3-10 | 3-8 |
Formatdifferent | Workshop + async | Workshop + async | Workshop |
