How much of the Sprint Backlog must be defined during the Sprint Planning meeting?

During the Sprint Planning meeting, it is essential to define enough of the Sprint Backlog to begin the Sprint and create forecasts effectively. The focus is on identifying a clear goal that the Scrum Team can pursue during the Sprint and understanding what work is necessary to achieve that goal. This approach allows the team to break down the selected Product Backlog items into actionable tasks while ensuring they are aligned with the Sprint Goal.

The objective is not to prescribe every detail of every task right from the start, as conditions and understanding may evolve during the Sprint. However, a solid foundation needs to be established to ensure that the team can make informed decisions and maintain progress toward achieving the Sprint Goal. This balance fosters flexibility and adaptability, which are central tenets of the Scrum framework.
