I have worked with several project managers who cite this article and claim to live by this ideal. However in practice they do everything but what is mentioned of a good product manager in the article. I don't know if I am biased or if the product managers, like most humans it would seem, fail to see themselves in a bad light (and thus correct themselves and set anew on a better path).<p>I also think that this is a subjective article, which, while it tries to list down the differences between good and bad traits of a product manager, fails to strongly separate the bad traits from the good ones by using vague management speak, and in general ends up making product managers feel goody goody about just being product managers.
