| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Operations Barrier Analysis |  Architecture SAAM (Software Architecture Analysis Method) |  Operations Root Cause 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. | When a problem keeps recurring and the cause stays unclear, the method exposes the underlying mechanism. It separates symptom, guess, and robust explanation from one another. |
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 | 1-4 h |
Participantsdifferent | Designers, developers as users, and facilitation | 2-6 | Architecture experts and stakeholders for scenarios and weighting | 3-8 |
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 | Barrier Inventory, Failure Analysis per Barrier, Action Backlog | 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 | Problem Statement, Cause Hypotheses, Confirmed Causes, Action Plan |
