11. From Size Estimate to Time Estimate First a reminder on velocity
12. Velocity Velocity is quite a simple concept. It is the measure of the number of units of work a team completed in a given time interval. This is commonly measured in story points completed per sprint. Velocity is the sum of the estimates of delivered (i.e., accepted) features per iteration.
13. Time Estimate Estimate = Total story points / Velocity Example: Total Story Points = 280 Velocity = 75 story points/sprint Estimate = 280/75 = 3.73 Sprints
