|---|---|---|---|
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. | For a complex deviation with several people involved, the method bundles problem, analysis, and decision onto one page. It creates a shared working space where causes, countermeasures, and follow-up fit together. | A Current Reality Tree condenses many symptoms into a few causal chains. The method makes visible which core problems drive several negative effects at once. |
Complexitydifferent | Medium | Medium | High |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 45-90 min | 2-6 h |
Participantsdifferent | Designers, developers as users, and facilitation | 2-5 | 3-8 |
Formatdifferent | Workshop + async | Workshop + async | Workshop |
Outputdifferent | Prioritized development tasks, Jointly produced code or pseudocode, Observed difficulties and open design questions, Proposed design revisions | A3 Report, Action Plan, Root Cause Analysis | Current Reality Tree, Core Problems, Intervention Ideas |
