How is the velocity of the team calculated when assessing their completed stories in a sprint?

The velocity of a team in Agile Scrum is computed by summing the story points of only the work that has been fully completed during a sprint. This means that only those stories that meet the Definition of Done and are considered "completed" contribute to the overall velocity. This approach provides a clear and accurate representation of the team's capacity and productivity, allowing for better forecasting in future sprints.

Using completed work ensures that the velocity reflects the team's real output, which can be reliably used for planning future sprints, estimating how much can be accomplished in upcoming cycles, and analyzing team performance over time. It emphasizes the importance of delivering potentially shippable increments of work rather than just engaging in tasks that may not yield finished user stories.
