## AI overview

This tutorial explains emergent properties in systems engineering, distinguishing nominal, weak, and strong emergence from resultant properties. It discusses how interactions and dependencies between system parts affect reliability, maintainability, predictability, and cost, with examples for technical leadership and engineering.
