1.	A Development Team maintains a Sprint burn-down to track estimated work remaining. In the middle of the Sprint, the burndown graph shows an upward Spike. What does it indicate?
Answer» This indicates that the DEVELOPMENT team ADDED new work. The line indicating EFFORT remaining in the burndown graph varies from team to team and day to day. If more work items (user stories and issues) are added after the sprint started then this shows an UPWARD spike. The spike indicates added work and the Product Owner cannot add new work to Sprint BACKLOG without the consent of the Team.
