| Criterion |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Delivery RAID Log |  Agile Specification by Example |
|---|---|---|---|
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. | Helps clarify scope, sequence, and delivery flow in concrete terms. It makes work, boundaries, and order steerable. The result is captured as a RAID Log and a source for status reporting. | When business rules need to become precise, it ties language, example, and test together. It sorts work by value, risk, and delivery ability. The result is captured as an Example Table and Acceptance Tests. |
Complexitydifferent | High | Low | Medium |
Timedifferent | Several meetings plus preparation and analysis; total effort depends on scope | 30 min Setup, dann laufend | 60-90 min pro Feature |
Participantsdifferent | Evaluation team, architects, and relevant stakeholders | 1-3 maintaining, briefing for everyone | 3-6 |
Formatdifferent | Workshop + async | Async | Workshop |
