| Criterion |  Decision Making Constraint Analysis |  Architecture LASR (Lightweight Approach for Software Reviews) |  Architecture arc42 |
|---|---|---|---|
Purposedifferent | When an initiative stalls, the limit often lies not in the idea but in hard or soft boundary conditions. Constraint Analysis separates these limits and shows which of them can actually be shaped. | 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. | 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. |
Complexitydifferent | Low | Medium | Low |
Timedifferent | 30-90 min | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-2 Tage |
Participantsdifferent | 2-8 | 1 or a small team; particularly suitable for 3–4 people | 1-4 |
Formatsame | Workshop + async | Workshop + async | Workshop + async |
Outputdifferent | Constraint List, Hard/Soft Classification, Option Impact Notes, Decision Boundaries | 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 | Architecture Document, Context View, Runtime View, Deployment View |
