Velocity
In plain terms
A measure of how much work a team completes per sprint.
Going deeper
Velocity tracks completed story points over sprints to forecast capacity and plan future work. It's a team-specific trend, not a target to maximize or compare across teams.
Under the hood
A planning aid, not a productivity metric; comparing it across teams or gaming it corrupts estimates. It stabilizes over several sprints.
Examples
Average 30 points/sprint, burndown charts, capacity forecasting.
Think of it like...
Like knowing your average pace on past runs to estimate how far you'll get next time, not a score to beat.
