| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Architecture C4 Model |  Operations Barrier Analysis |
|---|---|---|---|
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. | 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. | For a risk that can only be managed through multiple layers of protection, the method examines the effectiveness of each barrier. It shows where safeguards are missing, too weak, or fail under real conditions. |
Complexitydifferent | Medium | Low | Medium |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 1-4 h | 2-4 h |
