This feature is available in Catalyst, Enterprise, and Ultimate editions.
Sprint/Iteration specific metrics are available in two locations on the Sprint/Iteration Scheduling page.
On the left side of the page we see the following metrics for each Sprint/Iteration:
You can expand the Sprint/Iteration container using the '+' icon to see the same metrics for each team owning Backlog Items in the sprint/iteration
Selected Sprint/Iteration Metrics
On the right, at the top of the Backlog Grid for the selected Sprint/Iteration or Team.
The following metrics are visible in this control:
Planned - This number indicates the total amount of work1 in the backlog for the selected sprint/iteration or team at the end of the first day of the sprint/iteration. After the first day of the selected sprint/iteration, there will be a small lock icon next to this value. This icon indicates that the value is fixed and will no longer change when you add or remove backlog items from the sprint/iteration or team.
Target - This is a temporary number indicating a value you wish to reach when planning backlog items for the selected sprint/iteration or Team. When a Team is selected, this value will default based on the Target Estimate value for that Team.
Velocity - This number represents the average Velocity for the selected sprint/iteration or team, for the past 6 sprints/iterations.
The progress bar at the bottom provides visibility into how close you are to your target. The orange vertical line represents your desired target and the progress bar fill represents planned work. This bar remain green until you reach the target then it becomes red. This is only an indicator that your selected target has been exceeded; it is not necessarily a bad thing.
