| Criterion |  Engineering Fault Isolation |  Architecture LASR (Lightweight Approach for Software Reviews) |  Architecture ARID (Active Reviews for Intermediate Designs) |
|---|---|---|---|
Purposedifferent | In technical failures, the visible symptom often gets mixed up with the actual cause. Fault Isolation narrows the fault space and progressively reduces which part of the system is truly affected. | LASR helps development teams identify where their software falls short of important quality goals and which improvements to consider. A small group with existing system knowledge can make an initial assessment and investigate open questions in more detail. | 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. |
Complexitysame | Medium | Medium | Medium |
Timedifferent | 30-180 min | 3–4 h for initial assessment; preparation and deeper analysis additional | 2–4 h review as a planning range; preparation and evaluation additional |
