The Agile framework called Scrum defines three roles -- Product Owner, ScrumMaster and Development Team. Nowhere in the authoritative definition of Scrum, "The Scrum Guide", authored by Jeff Sutherland and Ken Schwaber, is there mention of a role, title, or person called a project manager. In fact, there is just one mention of the word "project" and that is in reference to a Sprint. The word "manager" doesn't appear even once. What is a project manager to do then in the context of Scrum?

Jim York, Certified Scrum Coach and Certified Scrum Trainer, shares insights on the three Scrum roles and the role of the project manager in Scrum.
