Awesome. A once-in-a-lifetime product was created without a incredibly narrowly focused definition of a product manager. The benefit of a product manager isn’t realized when you have that rare, world-changing product. A PM is useful when you have 47 incrementally better features on your backlog but only have the capacity to deliver 8 of them. Do you want to bet your career on being 8 for 8 on the features to deliver? Or would you rather work with someone who has done the research to help you decide what is important? The iPhone is a once in a lifetime innovation. Deciding whether the iPhone should allow the end user to select a default browser is a decision most engineers would rather delegate off to a product manager. The problem is a lot of engineers delude themselves into thinking they are working on the next iPhone when really they just aren’t.
