Who is responsible for determining how work is performed during the sprint?

The Development Team is responsible for determining how work is performed during the sprint because they are the ones who possess the skills and expertise necessary to execute the tasks involved in delivering the increment. According to Scrum principles, the Development Team is self-organizing, meaning that they decide how to tackle the work in the sprint backlog and determine the best techniques and methods to achieve their goals.

This decision-making authority empowers the Development Team to adapt their processes as needed, fostering an environment of collaboration and innovation. They assess their work capacity and select how they will collaborate throughout the sprint, leveraging their collective experience to ensure effective progress.

In contrast, the Product Owner's role centers around defining the "what" by managing the product backlog and ensuring that the team is delivering value to stakeholders. The Scrum Master acts as a facilitator and coach for the team, helping them adhere to Scrum practices but not directly influencing the day-to-day execution of the work. Stakeholders provide input and feedback but do not have a direct role in how development tasks are carried out within the sprint.
