| Criterion |  UX Research Surveys |  Architecture LASR (Lightweight Approach for Software Reviews) |  Product Discovery Test Card |
|---|---|---|---|
Purposedifferent | When a topic needs to be validated broadly and many people can answer the same question, surveys gather structured feedback in a scalable form. Answers become comparable and segmentable instead of remaining merely anecdotal. | 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. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. |
Complexitydifferent | Medium | Medium | Low |
Timedifferent | 3-14 Tage | 3–4 h for initial assessment; preparation and deeper analysis additional | 20-35 min |
Participantsdifferent | 50+ | 1 or a small team; particularly suitable for 3–4 people | 1-5 |
Formatdifferent | Async | Workshop + async | Workshop + async |
Outputdifferent | Survey Results, Charts, Segment Insights | 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 | Test Card with a pre-set threshold |
