Confidence Cone

See whether a target scope can realistically be delivered within a number of sprints, given a forecasted velocity range.

The cone between the two velocity lines is the range of outcomes your team might deliver.

Velocities from completed sprints

Enter at least two past sprint velocities. We compute a 95% prediction interval (Student's t) and feed the low/high range into the chart.
