Who is responsible for ensuring that each team member completes their tasks during the Sprint?

The Development Team is responsible for ensuring that each team member completes their tasks during the Sprint. The Scrum framework emphasizes self-organization and accountability, which means that the Development Team collectively owns the responsibility for delivering the Sprint goal. This collective ownership encourages team members to collaborate, support each other, and take shared responsibility for their commitments.

The Development Team's commitment to achieving the Sprint goal involves working together, communicating openly about progress, and addressing any impediments that may arise during the Sprint. Each team member is expected to take responsibility not only for their own tasks but also to engage with their peers to ensure smooth collaboration and progress.

By empowering the Development Team in this way, Scrum fosters an environment where team members actively contribute to each other's success, reinforcing the concept of teamwork in delivering high-quality increments of product. This is a fundamental principle of Scrum that distinguishes it from more traditional project management approaches where a designated manager may be responsible for task completion.
