Which of the following are active roles on a Scrum Team?

The active roles on a Scrum Team are defined within the Scrum framework, which consists of the Product Owner, the Scrum Master, and the Development Team. The correct choice highlights the Product Owner and Development Team as the essential active roles.

The Product Owner is responsible for maximizing the value of the product resulting from the work of the Development Team. They manage the Product Backlog and ensure that the team delivers value in alignment with stakeholder needs. The Development Team consists of professionals who work together to deliver a potentially releasable Increment of the product at the end of each Sprint. They are cross-functional, meaning they possess all the skills necessary to create the product Increment.

In contrast, the other options include roles that do not fit within the Scrum Team structure or are not officially recognized within the Scrum guidelines. For example, the Scrum Master is a vital role, but including a specific role like Tester or Project Manager does not align with the composition of a Scrum Team. Scrum emphasizes a team structure that fosters collaboration and self-organization without traditional roles like Project Manager, which may introduce hierarchy and fragmentation contrary to Scrum principles. Thus, the answer accurately reflects the active roles defined in Scrum.
