Step 1: The Sprint Planning Meeting

The Sprint Planning Meeting occurs before the beginning of a Sprint and is attended by the Product Owner, the Scrum Master, and the Team.  During this meeting the Product Owner describes the customer's highest priorities and the Team decides which priorities to move from the Product Backlog the the Sprint Backlog.  This meeting typically will take 8 hours with a 10 minute break every 2 hours and a lunch break after 4 hours.  For more details on this see the entry in the Scrum Glossary of Terms.
