| Criterion |  Architecture LASR (Lightweight Approach for Software Reviews) |  Growth A/B Testing |  Growth Growth Experiment |  Product Discovery Learning Card |
|---|---|---|---|---|
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 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 growth ideas surface quickly, the temptation to build immediately instead of learning is high. A Growth Experiment frames an assumption so target group, lever, and measurement are clear before the first deployment. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
Complexitydifferent | Medium | High | Medium | Low |
Timedifferent | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-4 Wochen | 1-2 Wochen | 25-40 min |
Participantsdifferent | 1 or a small team; particularly suitable for 3–4 people | 1-6 | 1-6 | 1-5 |
Formatdifferent | Workshop + async | Async | Workshop + async | Workshop + async |
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 | Experiment results, Decision log, Learning summary | Experiment card, Result summary, Next bet | Learning Card with evidence and next action |
