| Criterion |  Systems Thinking CATWOE Analysis |  Systems Thinking Rich Picture |  Architecture LASR (Lightweight Approach for Software Reviews) |
|---|---|---|---|
Purposedifferent | CATWOE structures a problem from six viewpoints and prevents too narrow a view of the situation. Different experiences of the system become comparably discussable this way. | A Rich Picture brings an unclear situation onto a shared drawing. It captures actors, tensions, information flows, and blind spots before the team jumps to solutions too early. | 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 | 30-90 min | 3–4 h for initial assessment; preparation and deeper analysis additional |
