|---|---|---|---|---|
Purposedifferent | 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 assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. | When several people work toward one goal but hold different mental maps, Alignment Mapping makes the discrepancies visible. It arranges goals, assumptions, and priorities so shared direction becomes verifiable. | 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. |
Complexitydifferent | Medium | Medium | Medium | High |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 45-60 min | 1-2 h | Several meetings plus preparation and analysis; total effort depends on scope |
Participantsdifferent | Designers, developers as users, and facilitation | 2-8 | 4-12 | Evaluation team, architects, and relevant stakeholders |
