First I didn't read the linked article but... I have yet to see a PM that actually performed PM duties that yielded a net positive for a company. If the PM doesn't have authority over developers the position devolves to a glorified QA position so that they are actually doing something useful. If they are given authority over developers they add a level of politics and stratification that ends up being a distraction to a team that otherwise works well together. Software developers have a lot of power to affect change and are generally anti-authority. Keeping an organization structure flatter seems to make software developers more productive. Given the choice I would avoid having a PM and just hire more intelligent software engineers. A quality QA person can give you the same effect without the mess. Note that I am separating project manager duties away from product manager duties.
