Method
How it Works
Velocity is a throughput model in story points per sprint, not an available-hours capacity model.
- Uses historical delivered story points across sprints to compute average and rolling velocity.
- Shows planning velocity and variability so sprint commitment can be set from throughput reality.
- Use with Team Capacity Calculator: capacity estimates available hours, velocity estimates likely points delivered.
Field Definitions
- Sprint -4/-3/-2/-1 points: Delivered story points for the last four completed sprints, from oldest (-4) to most recent (-1).
- Focus factor: Adjustment percentage for expected team availability and interruption load; 100% keeps historical average unchanged.
FAQ
Frequently Asked Questions
+How is velocity different from capacity?
Capacity is available productive hours; velocity is historical delivered story points per sprint.
+How many sprints should be included?
Use at least 3-6 recent comparable sprints to reduce noise from one-off events.
+Should velocity be treated as a hard target?
No. It is a planning baseline and should be adjusted for scope complexity and team changes.
