The Scrum Team consists of one Scrum Master, one Product Owner, and Developers. Within a Scrum Team, there are no sub-teams or hierarchies. It is a cohesive unit of professionals focused on one objective at a time, the Product Goal. The Scrum Master is accountable for establishing Scrum as defined in the Scrum Guide. They do this by helping everyone understand Scrum theory and practice, both within the Scrum Team and the organization. The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team. They are responsible for creating and communicating a vision, ordering the Product Backlog, and ensuring that the best possible job is done to delight customers. The Developers are the people in the Scrum Team that are committed to delivering a ''Done'' Increment that meets the Definition of Done and the Sprint Goal. They are responsible for managing and organizing their work within the Sprint, collaborating with the Product Owner and the Scrum Master, and applying their skills and creativity to create a product that delivers value to the stakeholders and customers. A Project Manager is not a role in the Scrum Team, as Scrum does not recognize titles for Developers, regardless of the work being performed by the person. There is no need for a Project Manager, as the Scrum Team is self-managing and accountable for delivering value.
