| Criterion |  Architecture LASR (Lightweight Approach for Software Reviews) |  Operations Fault Tree Analysis |  Operations MORT Analysis |
|---|---|---|---|
Purposedifferent | 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 critical top event with several possible triggers, the method logically models failure paths. It makes visible which combinations of conditions can lead to damage. | 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. |
Complexitydifferent | Medium | High | High |
Timedifferent | 3–4 h for initial assessment; preparation and deeper analysis additional | 2-6 h | Mehrere Tage bis Wochen |
Participantsdifferent | 1 or a small team; particularly suitable for 3–4 people | 3-8 | 2-6 |
Formatsame | Workshop + async | Workshop + async | Workshop + async |
Outputdifferent | Lean Mission Statement describing the software’s purpose, Prioritized quality goals and evaluation criteria, Risks and estimated gaps against quality goals, More closely examined findings and open checks | Fault Tree, Critical Paths, Cause Hypotheses, Control Actions | MORT Worksheets, Findings per Branch, Corrective Actions, Systemic Recommendations |
