When a friend asked me what I do, I started to explain it to her when she suddenly stopped me and asked: “You say 3 different titles, what is it exactly you’re doing?”
That start me thinking. It is only a name, why are there are so many names and are we not mis-using function names? My conclusion is that, depending on the organization your working for, Product Manager includes both the functions Project Manager and Product Owner.
I started to Google with my job description next to me. I was hired as a Product Manager. There are a lot of nice blogs about this subject here some good awnsers.
In the book; Inspired: How to Create Products Customers Love Hardcover – 2008 by Marty Cagan:
“to discover a product that is valuable, usable and feasible”
Martin Eriksson said in his blog:
“product management as the intersection between business, technology and user experience”
When Agile working method scrum came in to being, so did the SCRUM product owner. In my opinion a Product owner is a part of the Product Manager function.
Someone on a blog said, and I agree:
Product Owner is a role, not a job title, to be filled by someone with a real job title like (in many/most cases) Technical Product Manager.
A Project Manager’s job is to make sure a project is on time and on budget. That task often falls to the Product Manager (since they already have a high-level view of the project), but it’s a separate role that can be performed by a separate person.
