|---|---|---|---|
Purposedifferent | When a topic is still unclear and too many thoughts surface at once, Mind Mapping creates an open surface for ordering them. It makes connections, subtopics, and starting points visible without fixing them too early. | For a critical top event with several possible triggers, the method logically models failure paths. It makes visible which combinations of conditions can lead to damage. | 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. |
Complexitydifferent | Low | High | Medium |
Timedifferent | 15-45 min | 2-6 h | 3–4 h for initial assessment; preparation and deeper analysis additional |
Participantsdifferent | 1-10 | 3-8 | 1 or a small team; particularly suitable for 3–4 people |
Formatsame | Workshop + async | Workshop + async | Workshop + async |
Outputdifferent | Mind Map, Topic Clusters, Open Questions | Fault Tree, Critical Paths, Cause Hypotheses, Control Actions | 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 |
