Scott Adams had
Dilbert coin this
phrase in the
eponymous comic strip.
"What is constructive incompetence?"
"I had that written down someplace, but I lost it."
In The Joy of Work and other such Dilbert books, Mr Adams goes into more depth about how constructive incompetence can work for you! as a means to avoid work... "eventually you'll be in a far better position to say, `well, I could make those photocopies, but in the interests of efficiency, Ted would do a better job'."
