Who defines the amount of work to be completed during an iteration?

The team members define the amount of work to be completed during an iteration based on their understanding of the team's current capacity. This practice aligns with the principles of Agile methodologies, where the team is self-organizing and collectively responsible for determining how much work they can commit to in an iteration.

By assessing their capacity, which includes factors like team velocity, potential obstacles, and individual availability, the team can make informed decisions about what can realistically be accomplished. This approach fosters collaboration and ensures that the workload is manageable, ultimately leading to more sustainable development practices and higher-quality outputs.

The involvement of the whole team in this decision-making process encourages shared ownership of tasks and helps improve team dynamics, as everyone contributes to the planning based on their skills and insights. This choice reflects the core tenets of Agile, emphasizing collaboration, flexibility, and team accountability, rather than placing the responsibility solely on roles like the product owner or team lead.
