| Criterion |  UX Research First-click Testing |  Growth A/B Testing |  Architecture LASR (Lightweight Approach for Software Reviews) |  Product Discovery Smoke Test |
|---|---|---|---|---|
Purposedifferent | When users immediately turn the wrong way on a screen or wireframe, first click testing checks initial orientation at high speed. The first click shows early whether expectation, labeling, and wayfinding fit together. | 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. | 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 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 | Low | High | Medium | Low |
Timedifferent | 1-2 Tage | 1-4 Wochen | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-5 Tage |
Participantsdifferent | 10-30 | 1-6 | 1 or a small team; particularly suitable for 3–4 people | Nutzertraffic |
Formatdifferent | Async | Async | Workshop + async | Async |
Outputdifferent | Click Heatmap, Success Rate, Design Recommendations | Experiment results, Decision log, Learning summary | 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 | Interest Metrics, Conversion Signal, Learning Note |
