Quantitative metrics

In this section, we'll look at measurements that track quantities.

Team velocity

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&apos...
