Here’s a great post by Camille Fournier about The Product Culture Shift, and how every part of an engineering culture needs to change when product managers are added to traditional software infrastructure organizations.

To start, let’s be clear about one thing: as tempting as it might be, just hiring product managers won’t fix this problem. Even if you could find enough good product managers who want this type of job, which you can’t, product managers are only useful when they are paired with willing engineering teams. If the engineering teams don’t feel a sense of ownership for delivering a great product to their customers, product managers are unlikely to close that gap, and they will more likely turn into glorified backlog groomers than true product leaders.
