Calculating Sprint Velocity is a business tool used to measure the productivity of a team during a defined working period, such as a sprint. It evaluates the amount of work completed versus the amount of time allocated and provides an objective way to benchmark progress and success. As the sprint progresses, Sprint Velocity helps teams make informed decisions by providing insight into how productive they have been over time. By tracking progress and understanding the influencing factors behind it, teams can maximize their performance and reach their goals more efficiently.
