Velocity is a key metric which is used to measure the work delivered by an Agile team. While story points represent the effort required to complete a unit of work, they are subjective. Therefore, the velocity calculated using story points can be unreliable. However, function points, which quantify the functional size of software, provide a more objective and consistent basis for measuring velocity. By using function points, teams can gain a clearer understanding of their delivery speed and make more accurate predictions for future sprints. Delivery speed (velocity) based on function points is an important metric.
This short paper dives into the delivery-speed metrics of agile teams. To do so, it analyses the delivery speed of a sample of Java projects from the ISBSG Repository.
