|---|---|---|---|
Purposedifferent | 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. | When a team faces an open question with many obvious directions, the method first creates breadth instead of premature commitment. It separates idea flow from evaluation and makes lines of thought visible, creating a pool for selection and further development. |
Complexitydifferent | Medium | Medium | Low |
Timedifferent | 1-4 h | 3–4 h for initial assessment; preparation and deeper analysis additional | 30-60 min |
Participantsdifferent | 3-8 | 1 or a small team; particularly suitable for 3–4 people | 4-12 |
Formatdifferent | Workshop + async | Workshop + async | Workshop |
Outputdifferent | 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 | Idea pool, Theme clusters, Shortlist |
