Besides having excellent culinary skills, what other skill is absolutely necessary for a head cook?

An excellent head cook must not only be a skilled chef, but also must be an strong manager of people. From their position in the kitchen, the head chef will be responsible for delegating tasks to and overseeing the work of all those on the line and in the prep area, as well as with various operational aspects of the restaurant pertaining to supply ordering and procurement, front-of-house operations, and other key components of the restaurant's business.
