Velocity in Scrum is a measure of how much work a team can complete during a single sprint and is a key metric in Scrum. It is calculated at the end of each sprint by totaling the story points or other units of measurement for all fully completed user stories. Velocity helps teams to estimate the scope of delivery of the product and helps them to formulate a specific date at which they can deliver the product. It is used to determine the number of product backlog items to tackle during sprint planning, and based on this, both the amount of work and a delivery date can be estimated. Velocity is a powerful and simple method of measuring how much work is completed by the Developers at a given time and how much value they provide the business consistently. The average of the last three to five sprint velocities should be used for sprint planning. Velocity is not the same as productivity, as velocity is a metric primarily for planning and estimating how much work a team can handle in future sprints, while productivity is usually a broader measure that can include factors such as the quality of work, efficiency of processes, and value to the business. Teams can improve velocity by holding regular retrospective meetings to discuss what went well and what didnt go well in the previous sprint and how they can improve Sprint over Sprint to become better.
