Our job is to invent on behalf of the users.
People focused product management is about answering one question - how does the product add value to the user's life?
This alone is enough to take the team out of feature-and-benefits land to concentrating on the needs and challenges of the end user.
Building roadmaps around user needs focus on the user not and not the solution you might create giving you a touchpoint to come back to.
Being people focused in your design leads to lower acquisition costs, more active users, higher retention and growth over time.
If you don't have retention, you have nothing.
