One of my first gigs as a consultant was to write a project management system for a company that didn't really need a custom project management system. The CEO pulled me aside and told me the only important feature of the project management system was that you couldn't assign the same priority to two features. I would be blamed for making such a crappy project management system, but that's what I was there for. Once I was done, I was told to make myself hard to schedule and expensive.
