| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Operations Barrier Analysis |  Architecture SAAM (Software Architecture Analysis Method) |  Operations Change 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. | 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. | SAAM helps teams judge an architecture’s suitability for selected tasks and changes. It is particularly useful for examining modifiability and comparing architecture alternatives with clear reasoning. | For a deviation after a change, the method isolates the influence of the altered condition. It narrows down which differences are relevant and which are just accompanying noise. |
Complexitydifferent | Medium | Medium | High | Medium |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 2-4 h | Preparation, scenario analysis, and findings review; effort depends on scope | 45-120 min |
