|---|---|---|---|---|
Purposedifferent | For a tightly scoped process segment with noticeable waste, the method bundles shared energy for change. It suits situations that call for fast learning loops and visible adjustments. | arc42 structures architecture knowledge so teams can document system, decisions, and risks consistently. The template builds a living understanding of the architecture instead of scattered notes. | When a problem has several possible contributing factors, the method sorts causes by cause areas. It prevents an initial hunch from blocking the view of other plausible drivers. | 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 | Low | Medium |
Timedifferent | 0.5-5 Tage | 1-2 Tage | 30-60 min | 3–4 h for initial assessment; preparation and deeper analysis additional |
