| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Delivery MoSCoW |  Architecture C4 Model |
|---|---|---|---|
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 a release carries too many demands and priorities are only ever negotiated, MoSCoW creates clear boundaries for the next cut. Must, Should, Could, and Won't make commitment, room for maneuver, and trade-off logic visible to everyone involved. | The C4 Model makes a system legible across several resolution levels, from context down to code. It suits situations where different audiences need to understand the same architecture from different altitudes. |
Complexitydifferent | Medium | Low | Low |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 30-90 min | 1-4 h |
Participantsdifferent | Designers, developers as users, and facilitation | 3-12 | 1-5 |
