True story. A company was having problems with its development team. I was brought in to manage the team, to get things straightened out and act as a bridge between the developers and management. One of the folks on the management team asked me if I could recommend any books on the issues that address why they were having such problems with software development. I said there are a bunch, but start with the best, "Mythical Man Month". A few days later I asked him if he had bought it and started reading it. He said he looked at it, but it was really old so he didn't bother with it. He asked if there were more recent books I could recommend. I said, "Yes, but none of them are as good. Trust me, give this one a chance and we can talk about it's applicability to our situation." Again, a few days later we talked, and he decided he wasn't going to bother getting and reading it. I said, "Let me get this straight, you hired me for my insights into the software development process. You've seen me improve things around here. You asked me, presumably because you recognize I have some expertise in the field, what you should read, I told you, and you decided to go with your instincts on this matter over my judgment, is that correct?" To this day I have not received an answer to this question.
