Figure 11.1. Planned and actual velocity after the first three iterations.

Actual velocity, graphed through the third iteration, exceeded planned velocity for the first iteration. However, the actual improvements during the second and third iterations were not as great as planned and so actual velocity is slightly less than planned velocity.

The team of Figure 11.1 would have been wrong if, at the conclusion of the first iteration, they told the customer they were exceeding planned velocity and could move up the delivery date. What about after the three iterations shown? Can the team tell if they should adjust the customer’s expectations about the release plan? To answer that question the team needs both the velocity graph of Figure 11.1 as well as the cumulative story point graph of Figure 11.2.
