This document discusses crew resource management (CRM) and the relationship between stress/workload and performance known as the Yerkes-Dodson law. It provides a definition of CRM as focusing on interpersonal communication, leadership, and decision making, especially in aviation to improve air safety. The Yerkes-Dodson law shows that performance increases with arousal up to a point, after which higher stress decreases performance, illustrated by a bell curve. It also notes key points about stress, leadership, and learning from experience to aim for zero errors.
