Purposedifferent | When many visitors or users drop off along the way, the reason behind the number often stays hidden. Funnel Analysis exposes these transitions and makes visible exactly where the path collapses. | 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 two variants compete, discussions quickly decide by taste rather than effect. A/B Testing checks behavior under controlled conditions and separates real improvement from chance or expectation effects. | When demand only needs to be roughly verified, it tests interest with minimal effort. It measures whether people would take a next step at all. |
Complexitydifferent | Medium | Medium | High | Low |
Timedifferent | 1-3 h | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-4 Wochen | 1-5 Tage |
Participantsdifferent | 1-5 | 1 or a small team; particularly suitable for 3–4 people | 1-6 | Nutzertraffic |
Formatdifferent | Async | Workshop + async | Async | Async |
