It is a pretty good gig for making money. Scott Adams, the Dilbert cartoonist, has a very good take on business consultants. Basically, businesses (and governments) hire a consultant to come in and make recommendations on what to do, install a new system, etc. so when things go wrong they can blame the (by then long-gone) consultant. The consultant's main job is to go around interviewing management and employees until he can figure out what recommendations management wants him to make (if he recommends what they don't want, he won't get any repeat business from them), and then to package those recommendations into a presentation. It's pretty funny to read, but it's scary accurate.
