|---|---|---|---|
Purposedifferent | When an early product bet still has too many open points, it brings target group, problem, and assumptions into a single view. It condenses the idea so core risks become nameable. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | 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. |
Complexitydifferent | Medium | Low | Medium |
Timedifferent | 45-90 min | 20-35 min | 3–4 h for initial assessment; preparation and deeper analysis additional |
