| Criterion |  Operations Runbook |  Architecture Views and Beyond |  Architecture C4 Model |  Architecture ATAM (Architecture Tradeoff Analysis Method) |
|---|---|---|---|---|
Purposedifferent | For recurring operational tasks or incidents, the method keeps solid action logic ready. It reduces uncertainty when time pressure, role changes, or rare situations demand fast access. | Views and Beyond organizes architecture into several views so no single diagram has to do everything at once. This makes it possible to choose the representation that fits the stakeholder's question. | 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. | 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. |
