I believe the phenomenon you're talking about is called "Peter principle" [1], which states that "people in a hierarchy tend to rise to their level of incompetence. In other words, an employee is promoted based on their success in previous jobs until they reach a level at which they are no longer competent".

No, he's talking about something different. The Peter Principle makes the process sound totally dysfunctional because it assumes the employee will remain incompetent, while he suggests that a period of incompetence is necessary to learn how to do your job.

He didn't mention people being incompetent. Why do you say he's talking about the Peter principle? I can't see it.
