You are a Scrum Master for a team. Near the end of the Sprint, your Product Owner approaches you with a problem. She tells you she noticed that the Developers have not begun work on her highest value item yet. In Sprint Planning, everyone agreed that the item was critical to achieving the Sprint Goal and the Developers had originally forecast that the work would take almost half of the Sprint to complete.
