|---|---|---|---|
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 a lot is assumed about a target group but little is seen jointly, empathy mapping makes knowledge and gaps directly comparable. The picture also shows which assumptions hold up and where evidence is missing. | 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. |
Complexitydifferent | Medium | Low | Low |
Timedifferent | 3–4 h for initial assessment; preparation and deeper analysis additional | 30–60 min | 15-30 min |
Participantsdifferent | 1 or a small team; particularly suitable for 3–4 people | 4-8 | 2-6 |
Formatdifferent | Workshop + async | Workshop | Workshop |
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 | Empathy Map, Assumptions List, Research Gaps | Root cause notes, Countermeasures |
