Too Long; Didn't Read
Product Manager as a function or practice is fairly old now. It originated from a memo written by Neil McElroy, an Advertising Manager at Proctor and Gamble. He suggested the need of a “brand man”, a person solely responsible for the product and not the business. But I am sure we all would agree that now a days Product Management has become a vital practice in every Product Organization. Yet, I come across quite many folks who do not understand the differences between a Product Manager, Project Manager and Product Marketing Manager.
