When did people first start to delegate authority?

I was thinking about how annoying bureaucracies can be and got to wondering at what point in social development there originated the idea of delegating authority to someone else, which is the organizing principle behind bureaucracies.

Hunter-gatherers live in small groups based on extended families and are fairly egalitarian.

What about nomads? Do flocks ever get large enough to require hiring someone to tend them and to hire others to act as supervisors?

I would think that delegating authority came into its own with the start of agriculture when land ownership made it possible for a single family to produce enough to require hiring others to help with management.

How necessary is bureaucratic organization? I read from time to time about businesses organized as coops. I wonder how large a part of the overall economy that such businesses could become.
