|---|---|---|---|
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. | 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. | 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 | Low | Low |
Timedifferent | 3–4 h for initial assessment; preparation and deeper analysis additional | 15-30 min | 30-60 min |

Formatdifferent | Workshop + async | Workshop | Workshop |
