| Criterion |  Knowledge Modeling PARA Method |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Architecture C4 Model |
|---|---|---|---|
Purposedifferent | The PARA Method organizes knowledge into Projects, Areas, Resources, and Archives. It creates order when digital notes, files, and tasks no longer cleanly fit current work. | ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation. | 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 | Medium | High | Low |
Timedifferent | 1-3 h Setup, laufend | Several meetings plus preparation and analysis; total effort depends on scope | 1-4 h |
