The Peter (Buttigieg) Principle

In the 1960s, there was a professor and business analyst named Laurence J. Peter. He became famous for coming up with something called the Peter Principle. The informal way to describe it was this: In a business hierarchy, an employee does well and is promoted. He does well in his new, higher-level job and is promoted again. He does well in that position and is promoted yet again. Finally, he rises to a job that is beyond his abilities. He is no longer promoted and stays in the job he does not do well.
