|---|---|---|---|
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. | When experiments become unreadable after the fact, it arranges hypothesis, signal, and learning goal on a single canvas. It separates problem, assumption, solution, and evidence. The result is captured as a Completed Experiment Canvas and a Success Metric. | When an idea hinges on one critical unknown, it prioritizes testing that exact piece of uncertainty first. It separates problem, assumption, solution, and evidence. The result is captured as a prioritized list of assumptions, a test plan, and a result report. |
Complexitydifferent | Medium | Low | Medium |
Timedifferent | 3–4 h for initial assessment; preparation and deeper analysis additional | 30-60 min | 1-2 Wochen pro Iteration |
Participantsdifferent | 1 or a small team; particularly suitable for 3–4 people | 1-5 | 2-6 |
Formatsame | Workshop + async | Workshop + async | Workshop + async |
