Polymaths exist, but are not the norm. I've more often run across the opposite, where people who are good in one area are not good at all in another. For example many people who are very good programmers are very poor salespeople, and vice-versa, which is one reason you don't have your sales team and your programming team be the same. Good programmers and good documentation writers are often not the same people either. At least among my colleagues, I definitely have a sense that I should ask A for some things, and B for others.
