|---|---|---|---|---|
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 many visitors or users drop off along the way, the reason behind the number often stays hidden. Funnel Analysis exposes these transitions and makes visible exactly where the path collapses. | ARID examines how well developers can work with a technical design. It focuses on a part of the system that can still be revised, between the architecture overview and the detailed specification. | When two variants compete, discussions quickly decide by taste rather than effect. A/B Testing checks behavior under controlled conditions and separates real improvement from chance or expectation effects. |
Complexitydifferent | High | Medium | Medium | High |
Timedifferent | Several meetings plus preparation and analysis; total effort depends on scope | 1-3 h | 2–4 h review as a planning range; preparation and evaluation additional | 1-4 Wochen |
Participantsdifferent | Evaluation team, architects, and relevant stakeholders | 1-5 | Designers, developers as users, and facilitation | 1-6 |
