|---|---|---|---|---|
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 an early product bet still has too many open points, it brings target group, problem, and assumptions into a single view. It condenses the idea so core risks become nameable. | The method protects energy and attention for the task that creates the largest progress and is often postponed. | It separates true priorities from noise so it becomes clear what should be done now, scheduled, delegated, or dropped. |
Complexitydifferent | Medium | Medium | Low | Low |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 45-90 min | 15-90 min daily | 15-30 min |
Participantsdifferent | Designers, developers as users, and facilitation | 1-6 | 1 | 1-6 |
Formatdifferent | Workshop + async | Workshop + async | Async | Workshop + async |
Outputdifferent | Prioritized development tasks, Jointly produced code or pseudocode, Observed difficulties and open design questions, Proposed design revisions | Lean Canvas, Core Assumptions, Experiment Backlog | Priority Task, Completion Note, Daily Focus | Eisenhower Matrix, Action List, Delegation Notes |
