|---|---|---|---|
Purposedifferent | When teams derive needs only from assumptions and real motives are missing, user interviews give direct access to behavior and meaning. Conversations from the target group's everyday life make patterns, tensions, and open questions solidly visible. | 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 an acute quality or delivery problem, the method structures immediate protection and root cause work together. It keeps the situation stable while the actual cause is investigated cleanly. |
Complexitydifferent | Low | Medium | High |
Timedifferent | 30–60 min per interview | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-6 Wochen |
Participantsdifferent | 1 participant per interview | 1 or a small team; particularly suitable for 3–4 people | 4-10 |
