I wrote a post here a while ago, in an attempt to get some action and input from the community of product managers online to strive to come to a conclusion about the basic elements about our role within an organization.
One of my friends, Saeed, has begun the journey of taking this to the next level – I encourage everybody to check out his post and contribute to his survey.
This can only help the community, and the evolution of the product management role, so do your part.
Good job, Saeed!
