“One challenge is the Peter Principle. Coined by Dr. Laurence J. Peter and Raymond Hull in their 1969 book of that name, the Peter Principle holds that in a hierarchy, members are promoted so long as they work competently. Sooner or later they are promoted to a position at which they are no longer competent (their “level of incompetence”), and there they remain being unable to earn further promotions.”

“Some people are so belligerent in their communication style that people just stop talking when they are in the room. If every time anyone brings up an issue with the marketing organization, the VP of marketing jumps down their throats, then guess what topic will never come up? This behavior can become so bad that nobody brings up any topic when the jerk is in the room. As a result, communication across the executive staff breaks down and the entire company slowly degenerates. Note that this only happens if the jerk in question is unquestionably brilliant. Otherwise, nobody will care when she attacks them. The bite only has impact if it comes from a big dog. If one of your big dogs destroys communication on your staff, you need to send her to the pound.”
