|---|---|---|---|---|
Purposedifferent | When a problem has several possible contributing factors, the method sorts causes by cause areas. It prevents an initial hunch from blocking the view of other plausible drivers. | The method protects energy and attention for the task that creates the largest progress and is often postponed. | 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. | With a restless workday full of too many open items, the method creates radical simplicity. It directs attention to a short sequence instead of a broad, still-open field. |
Complexitydifferent | Low | Low | Medium | Low |
Timedifferent | 30-60 min | 15-90 min daily | 3–4 h for initial assessment; preparation and deeper analysis additional | 5-10 min daily |
Participantsdifferent | 2-8 | 1 | 1 or a small team; particularly suitable for 3–4 people | 1 |
Formatdifferent | Workshop | Async | Workshop + async | Async |
Outputdifferent | Fishbone Diagram, Cause Categories, Investigation Backlog | Priority Task, Completion Note, Daily Focus | 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 | Daily Priority List, Completion Notes |
