Can I also add the following things: the passing of the buck, unnecessary competition, brutal micromanagement, since marketing is "easy" everyone feels they are an expert, having to take responsibility for the failures but rarely getting credit for the wins, fighting for resources (even when you have the numbers on your side)... I think a company where sales and marketing becomes more about politics and less about analysis and creativity is doomed to fail (or at least not achieve its real potential).
