| Criterion |  Architecture LASR (Lightweight Approach for Software Reviews) |  Operations Root Cause Analysis |  Operations Causal Factor 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. | 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. | For an event with a complicated course, the method breaks down the contributing factors along the timeline. It shows how conditions, decisions, and reactions together produce a course of events. |
Complexitydifferent | Medium | Medium | High |
Timedifferent | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-4 h | 2-6 h |
