| Criterion |  Delivery Communication Plan |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Knowledge Modeling Teach-back |
|---|---|---|---|
Purposedifferent | When many people need to be informed in parallel and messages would otherwise arrive unevenly or too late, a Communication Plan orders communication reliably. Channels, audiences, and cadences interlock so important information doesn't get lost. | 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. | 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. |
