In the previous installment of this series, we talked about scaling application designs and breaking those designs into tasks and estimates in preparation for scheduling. Now let’s take a look at how to go about building that schedule. The Scrum metric for capacity or work completed over time is Velocity.

Scrum teams use Story Points to calculate their Velocity, a…
