Velocity Formula:
From: | To: |
Velocity is a metric that measures the amount of work a team completes during a sprint. It's calculated by dividing the total story points completed by the sprint duration.
The velocity formula is simple:
Where:
Explanation: Velocity helps teams predict how much work they can complete in future sprints based on their historical performance.
Details: Velocity is crucial for sprint planning, helping teams commit to realistic amounts of work and improve their estimation accuracy over time.
Tips: Enter the total story points completed during the sprint and the sprint duration. You can calculate velocity in points per day or points per week.
Q1: What's a good velocity for a team?
A: There's no universal "good" velocity - it varies by team. What matters most is consistency over several sprints.
Q2: Should velocity increase over time?
A: Velocity should stabilize as estimation improves. Sudden increases may indicate estimation changes rather than productivity gains.
Q3: How many sprints should we track to get reliable velocity?
A: Typically 3-5 sprints are needed to establish a reliable velocity range.
Q4: What if our velocity varies greatly between sprints?
A: Large variations may indicate inconsistent estimation, changing team composition, or external factors affecting productivity.
Q5: Can we compare velocities between different teams?
A: No, velocity is team-specific due to different estimation scales and working styles.
