| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Architecture SAAM (Software Architecture Analysis Method) |  Operations Change Analysis |  Engineering Fault Isolation |
|---|---|---|---|---|
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. | 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. | 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. |
Complexitydifferent | Medium | High | Medium | Medium |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | Preparation, scenario analysis, and findings review; effort depends on scope | 45-120 min | 30-180 min |
Participantsdifferent | Designers, developers as users, and facilitation | Architecture experts and stakeholders for scenarios and weighting | 2-6 | 1-6 |
Formatsame | Workshop + async | Workshop + async | Workshop + async | Workshop + async |
Outputdifferent | Prioritized development tasks, Jointly produced code or pseudocode, Observed difficulties and open design questions, Proposed design revisions | Domain functions mapped to components and connections, Quality attributes and evaluation criteria, Typical tasks and their effects on the architecture, Reasoned evaluation or comparison of alternatives | Change Matrix, Cause Hypotheses, Validation Questions, Action List | Fault Isolation Map, Test Log, Excluded Hypotheses, Narrowed Fault Area |
