| Criterion |  Agile WSJF |  Architecture arc42 |  Operations Root Cause Analysis |  Architecture LASR (Lightweight Approach for Software Reviews) |
|---|---|---|---|---|
Purposedifferent | When many tasks compete for the same capacity, it orders work by economic impact. It makes time lost, benefit, and effort comparable together. | arc42 structures architecture knowledge so teams can document system, decisions, and risks consistently. The template builds a living understanding of the architecture instead of scattered notes. | 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. | 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. |
Complexitydifferent | High | Low | Medium | Medium |
Timedifferent | 45-90 min | 1-2 Tage | 1-4 h | 3–4 h for initial assessment; preparation and deeper analysis additional |
Participantsdifferent | 3-10 | 1-4 | 3-8 | 1 or a small team; particularly suitable for 3–4 people |
Formatdifferent | Workshop | Workshop + async | Workshop + async | Workshop + async |
Outputdifferent | Ranked Backlog, Cost-of-Delay Assumptions | Architecture Document, Context View, Runtime View, Deployment View | Problem Statement, Cause Hypotheses, Confirmed Causes, Action Plan | 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 |
