This question is often confusing. What is the difference between the two?
They are very similar. After all, a product manager identifies market needs. This manager also has a road map, and decides feature acceptance criteria.
Product Manager is not synonymous of Product Owner, even though the same person can be both.
In Scrum, a product owner is a role, it is not a job. Anyone selected can be a product owner. In some organizations, this is a highly technical position, in others it is a very market/customer position, from marketing or sales.
Difference between a Scrum product owner and product manager
A product manager (a job) can absolutely be a product owner (a role).
It is simply not a requirement that a product manager takes on the role.
For example, in organizations with several Scrum teams, each team may select a technical product owner for the role. And this person will work with the organization's product manager, as an external stakeholder.
Here are the key differences to remember
So, in Scrum the product owner has the role to make sure the team is working on the right stories, from a backlog the product owner manages.
Also, the product owner makes sure sprint deliver what was agreed upon.
