| Criterion |  Architecture C4 Model |  Growth Funnel Analysis |  Architecture LASR (Lightweight Approach for Software Reviews) |  Architecture arc42 |
|---|---|---|---|---|
Purposedifferent | The C4 Model makes a system legible across several resolution levels, from context down to code. It suits situations where different audiences need to understand the same architecture from different altitudes. | When many visitors or users drop off along the way, the reason behind the number often stays hidden. Funnel Analysis exposes these transitions and makes visible exactly where the path collapses. | 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 | Medium | Low |
Timedifferent | 1-4 h | 1-3 h | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-2 Tage |
Participantsdifferent | 1-5 | 1-5 | 1 or a small team; particularly suitable for 3–4 people | 1-4 |
Formatdifferent | Workshop + async | Async | Workshop + async | Workshop + async |
Outputdifferent | Context Diagram, Container Diagram, Component Diagram | Funnel report, Drop-off analysis, Optimization hypotheses | 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 |
