| Criterion |  Architecture C4 Model |  Knowledge Modeling Knowledge Mapping |  Architecture LASR (Lightweight Approach for Software Reviews) |  Knowledge Modeling Concept Mapping |
|---|---|---|---|---|
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. | Knowledge Mapping makes knowledge, gaps, and transfer paths visible across a field. It fits when expertise should not just exist but also be findable and transferable. | 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. | Concept Mapping arranges terms and relationships in a network that makes subject-matter connections tangible. It fits when a topic needs to be understood structurally rather than linearly. |
Complexitydifferent | Low | Medium | Medium | Medium |
Timedifferent | 1-4 h | 1-3 h | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-2 h |
Participantsdifferent | 1-5 | 3-12 | 1 or a small team; particularly suitable for 3–4 people | 1-8 |
Formatdifferent | Workshop + async | Workshop | Workshop + async | Workshop + async |
Outputdifferent | Context Diagram, Container Diagram, Component Diagram | Knowledge Map, Critical Knowledge Areas, Transfer Plan | 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 | Concept Map, Relationship Labels, Knowledge Gaps |
