Work out velocity (agile) instantly with clear inputs, formula shown and shareable results.
Velocity is the points completed per sprint, best used as an average over several sprints rather than a single reading. The standard deviation matters as much as the mean: a stable velocity supports forecasting, a volatile one means any forecast needs a wide range.
Average velocity
Average = Sum of points completed / Number of sprints
Predictability
Predictability % = 100 - Standard deviation / Average x 100
No. Making velocity a target causes point inflation and destroys its usefulness as a forecasting input.
Three to five. Fewer is noisy; more masks genuine changes in team composition or working practice.
