As a business systems analyst (Product Owner in agile terms) for a fotune 500 company, thank you for this comment. You uplifted my spirits. Also, I agree with most of it, but I would argue that the best teams I've been on have at least one extremely competent developer, even if not necessarily a great one. Why? Because I can articulate the product vision and goals working closely with that developer, and together we can make sure the other developers are developing as required. In an ideal world developers would have all the domain and functional knowledge required to not need people like myself. But the truth of the matter is, that the higher up you go, the more specialized you become, the more you need to do only one or the other. There are only so many hours in the day - you can either hone your skills as a developer or develop the expertise of keeping multiple business stakeholders happy while holding your own against developers and delivering in a consistent fashion.
