Who primarily determines how the work is performed during a Sprint?

The Development Team primarily determines how the work is performed during a Sprint because they are the individuals with the necessary skills and knowledge to complete the tasks. In Scrum, the Development Team is empowered to decide which approaches and techniques to use in order to deliver the increment of potentially shippable product at the end of the Sprint. They self-organize to manage their work and make decisions about their processes, tools, and the best way to collaborate.

This autonomy is crucial to fostering a collaborative environment where the team can leverage their expertise effectively. The Scrum Master facilitates their processes and protects the team from external interference, while the Product Owner focuses on prioritizing the backlog and ensuring that the team understands the requirements. Outside stakeholders provide input and feedback but do not dictate how the team operates during the Sprint. This division of responsibilities reinforces the Development Team's ownership of the work they produce.
