For instance, during Sprint planning, we are called to decide on how many Product Backlog items we can work on during the Sprint. This is impossible to do without having some prior knowledge of our team's capacity or ability to deliver work. We usually employ the metric of velocity to forecast the work we can deal with during the Sprint. In addition, many Agile teams use burnup and burndown charts to track progress at any point during the Sprint. In this section, we'll examine these three metric concepts.
