There's also a entire subject devoted to management which has nothing to do with the products, and everything to do with the personalities, the processes, and culture.In business school, a lot of course study is about the forensics of business, finding out what went wrong. Ultimately, it is about the product, not the personalities, so a chevy is a chevy, apple an apple, and dnd is dnd. Gary did ok until he didn't, which is the same old story with business.
