| Criterion |  Architecture C4 Model |  Architecture LASR (Lightweight Approach for Software Reviews) |  Growth A/B Testing |
|---|---|---|---|
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. | 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 two variants compete, discussions quickly decide by taste rather than effect. A/B Testing checks behavior under controlled conditions and separates real improvement from chance or expectation effects. |
Complexitydifferent | Low | Medium | High |
Timedifferent | 1-4 h | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-4 Wochen |
Participantsdifferent | 1-5 | 1 or a small team; particularly suitable for 3–4 people | 1-6 |
Formatdifferent | Workshop + async | Workshop + async | Async |
Outputdifferent | Context Diagram, Container Diagram, Component Diagram | 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 | Experiment results, Decision log, Learning summary |
