| Criterion |  Operations Waste Analysis |  Architecture ARID (Active Reviews for Intermediate Designs) |
|---|---|---|
Purposedifferent | For a process that keeps people busy but creates little value, the method exposes waste. It directs attention to unnecessary movement, waiting times, rework, and overdelivery. | 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. |
Complexitydifferent | Low | Medium |
Timedifferent | 45-120 min | 2–4 h review as a planning range; preparation and evaluation additional |
Participantsdifferent | 2-8 | Designers, developers as users, and facilitation |
Formatdifferent | Workshop | Workshop + async |
Outputdifferent | Waste Map, Prioritized Waste, Improvement Backlog | Prioritized development tasks, Jointly produced code or pseudocode, Observed difficulties and open design questions, Proposed design revisions |
