| Criterion |  Operations MORT Analysis |  Architecture LASR (Lightweight Approach for Software Reviews) |  Operations Barrier Analysis |
|---|---|---|---|
Purposedifferent | For a safety-relevant event or a system with high protection requirements, the method examines where controls failed. It exposes both technical and organizational gaps. | 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. | 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 | High | Medium | Medium |
Timedifferent | Mehrere Tage bis Wochen | 3–4 h for initial assessment; preparation and deeper analysis additional | 2-4 h |
