Interactive Lean and Agile Management Calculator

Velocity Forecasting

Use historical team velocity to estimate future delivery ranges, test the effect of forecast windows and variability, forecast backlog completion and see how changing capacity or scope growth alters the expected delivery range.

At a Glance
Primary Focus Historical velocity and delivery ranges
Typical Duration 12–18 minutes
Learning Format Direct-manipulation forecasting calculator
Best For Agile teams, product practitioners and delivery leaders
Overview

Velocity forecasting should communicate a range, not manufacture certainty.

The tool uses recent completed-work history to calculate a central velocity estimate and an illustrative low-to-high planning range. Learners can change the historical window, backlog size, future capacity and scope-growth assumptions to see how the forecast responds.

Guided Demonstration

Velocity Forecasting — Step by Step

Eight locked stages move from forecast context through velocity history, forecast basis, historical spread, remaining backlog, future conditions, a delivery shock and management review.

Experiment Mode

Test a Delivery Forecast

Experiment Mode is isolated from the guided demonstration. Change the historical window, backlog size, future capacity and expected scope growth to see how the completion range changes.

Quick Reference

Velocity-forecasting cues

Velocity

Story points or other relative units actually completed by the team in a sprint.

Mean

Arithmetic average of the selected sprint history; sensitive to unusually high or low sprints.

Median

Middle value of the selected history; less influenced by an extreme observation.

Historical Spread

Use variability to create an illustrative planning range rather than a single deterministic value.

Scope Growth

New work entering the backlog reduces net burn-down and can materially extend the forecast.

Velocity Is Team-specific

Do not compare teams mechanically or convert story points into a universal number of hours.

Key Takeaway
Forecast from evidence, communicate a range and update the forecast when the evidence changes.

Use recent team history, visible assumptions and an uncertainty range. When capacity or scope changes materially, revise the forecast rather than defending the old date.
