|---|---|---|---|
Purposedifferent | For a single, hard-to-explain deviation, the method exposes the causal chain behind the visible symptom. It keeps the cause open until a controllable condition emerges instead of a mere description. | 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 complex deviation with several people involved, the method bundles problem, analysis, and decision onto one page. It creates a shared working space where causes, countermeasures, and follow-up fit together. |
Complexitydifferent | Low | Medium | Medium |
Timedifferent | 15-30 min | 3–4 h for initial assessment; preparation and deeper analysis additional | 45-90 min |
Participantsdifferent | 2-6 | 1 or a small team; particularly suitable for 3–4 people | 2-5 |
Formatdifferent | Workshop | Workshop + async | Workshop + async |
Outputdifferent | Root cause notes, Countermeasures | 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 | A3 Report, Action Plan, Root Cause Analysis |
