| Criterion |  Knowledge Modeling Teach-back |  Operations Bottleneck Analysis |  Architecture LASR (Lightweight Approach for Software Reviews) |  Architecture C4 Model |
|---|---|---|---|---|
Purposedifferent | Teach-back checks whether an explanation actually got through to the other person. The method makes misunderstandings visible early and strengthens shared understanding in advisory and learning situations. | For a flow that backs up at one point, the method looks for the capacity limit with the greatest leverage. It explains why extra effort elsewhere barely improves throughput. | 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. | 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. |
Complexitydifferent | Low | Medium | Medium | Low |
Timedifferent | 5-20 min | 1-3 h | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-4 h |
Participantsdifferent | 2-8 | 3-8 | 1 or a small team; particularly suitable for 3–4 people | 1-5 |
