A managers role has the potential to be extremely effective.
Because their income is typically tied to results as opposed to hours, they reap the benefits of a well levered resource.

An effective Sales and Marketing Manager, VP, or Director knows which 20% of his inputs product 80% of the output.
She knows what work they’re effective at, and delegates the rest.
She knows when an employee needs more training and when to hire new.
