Scrum framework : Velocity

Velocity definition

Velocity purpose

  • Velocity is the primary measure of development speed.
    • Velocity represents the rate of development progress.

Velocity practice

  • Velocity is usually expressed as Product Backlog Items completed (and tested) per iteration.
    • Developers track the velocity for use within the Scrum Team.
    • An agile team can use its previous velocity recordings as a method of estimating how many user story points it may complete in the next iteration. [Agile Estimating and Planning. Mike Cohn].
    • Estimating how many user story points a team can complete in a Sprint/iteration should be based upon its previous iterations, if possible.
    • If Kyle’s team estimated 45 story points in its first Sprint but completed only 30 story points, it would be wise to estimate no more than 30 for its next Sprint/iteration. [Agile Estimating and Planning. Mike Cohn].
    • Velocity is a measure of the number of user story points or stories completed by a team per iteration. An agile team can use its previous velocity recordings as a method of estimating how many user story points it may complete in the next iteration. [Agile Estimating and Planning. Mike Cohn.]
