| Criterion |  Architecture LASR (Lightweight Approach for Software Reviews) |  Product Strategy Impact Mapping |  Product Discovery Assumption Mapping |
|---|---|---|---|
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 a goal needs to be connected to several possible paths, it shows chains of impact instead of feature lists. It connects business goal, behavior change, and measures. | When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. |
Complexitysame | Medium | Medium | Medium |
Timedifferent | 3–4 h for initial assessment; preparation and deeper analysis additional | 45-90 min | 45-60 min |
