Each sprint is proceded by a planning meeting. Product owner presents list of requirements from customer and the team estimates these requirements with Scrum cards.
The set of features that go into a sprint come from the product backlog to the sprint backlog.
No one allowed to change sprint backlog after planning
Daily Stand-up
Each day during the sprint a project status meeting occurs. This is called a daily scrum or the daily stand-up. During this meeting each team memeber answers three questions.
