The document discusses issues that Scrum teams often face during sprint planning when user stories are prioritized but lack clarity. It proposes splitting the sprint planning meeting into two shorter sessions to address these issues. In the first session at the end of the previous sprint, the product owner defines the sprint goal and selects backlog items while the Scrum Master works to clarify any unclear stories. In the second session on the planning day, the team estimates stories, the product owner prioritizes, and the team selects stories for the sprint along with stretch goals to increase velocity.
