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.

Agile methodologies emphasize flexibility and continuous adaptation, but clear requirements are still crucial for efficient development. The effective management of project requirements can: contribute to a team’s ability to deliver working software in short iterations, minimize rework caused by misunderstandings, ensure the final product aligns with stakeholder expectations. This short paper investigates the impact of the effort spent on the design phase and its impact on productivity, in agile software development projects.
