Calculate the velocity for an Agile team by adding together all of the estimates for the completed User Stories in a Sprint. For example, if the team is using Story Points to estimate and complete five User Stories with estimates of 5, 2, 2, 3, and 1 respectively, then their velocity is 5 + 3 + 2 + 2 + 1 = 13.
If our team is estimating T-shirt sizes, it's not possible to say your velocity is 1L + 1M + 2S + 1XS, as this isn't easy to translate from Sprint to Sprint. Instead, assign numbers to each t-shirt size, for example, XS=1, S=2, M=3, L=5, and XL=8. Apply this method to any sizing system that doesn't use numbers.
Velocity is a metric that is used by the team for forecasting. For instance, during Sprint Planning we use it ...
