The subject of a book of the same name by Scott Adams. The basic idea is that idiots are promoted to management in companies, where they can do the least damage. Unfortunately, this tends to happen before they've acquired any actual skills, so instead of being managed by an idiot who was at least once good at someting, you end up just being managed by an idiot.

Compare: The Peter Principle.

Book review

The Dilbert Principle is, frankly, an amazing work. Quite how Scott manages to be so repeatedly funny is beyond me, and every single page is littered with comics, witty analogies and gags. This is no small achievement for a book so large - many aspects of the corporate world are covered, including teamwork, ISO 9000, managers and the habits of those strange creatures - the scientist and the engineer.

If you're a fan of Scott's unique brand of humor, don't give this a miss.
