|---|---|---|---|
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. | A Current Reality Tree condenses many symptoms into a few causal chains. The method makes visible which core problems drive several negative effects at once. | For an event with a complicated course, the method breaks down the contributing factors along the timeline. It shows how conditions, decisions, and reactions together produce a course of events. |
Complexitydifferent | Medium | High | High |
Timedifferent | 3–4 h for initial assessment; preparation and deeper analysis additional | 2-6 h | 2-6 h |
Participantsdifferent | 1 or a small team; particularly suitable for 3–4 people | 3-8 | 3-10 |
Formatdifferent | Workshop + async | Workshop | Workshop + async |
Outputdifferent | 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 | Current Reality Tree, Core Problems, Intervention Ideas | Event Timeline, Causal Factor Chart, Cause List, Corrective Actions |
