How much of the Sprint Backlog must be defined during the Sprint Planning event?
(choose the best answer)
Just enough tasks for the Scrum Master to be confident in the Development Team's understanding of the Sprint.
The entire Sprint Backlog must be identified and estimated by the end of the Sprint Planning meeting.
Enough so the Development Team can create its best forecast of what it can do, and to start the first several days of the Sprint.
Just enough to understand design and architectural implications.
