Burndown vs Velocity
A burndown chart tracks remaining work within a single cycle, sloping toward zero as items finish — it answers 'are we on pace to finish this cycle?' Velocity is the average work completed per cycle across several cycles — it answers 'how much can we realistically take on next time?' Burndown is an in-cycle progress monitor; velocity is a cross-cycle planning input, and the two are best read together.
Burndown vs Velocity, in short
- A burndown chart tracks remaining work within a single cycle, sloping toward zero as items finish — it answers 'are we on pace to finish this cycle?' Velocity is the average work completed per cycle across several cycles — it answers 'how much can we realistically take on next time?' Burndown is an in-cycle progress monitor; velocity is a cross-cycle planning input, and the two are best read together.
- When to use burndown: Use burndown during a cycle to spot slippage, stalled work, or scope creep early enough to react.
- When to use velocity: Use velocity before a cycle to set a realistic commitment based on the team's proven historical capacity.

| Definition | A burndown chart tracks remaining work against time over a cycle, sloping from the total scope down toward zero as items are completed. It shows whether a team is on pace to finish what it committed to, making slippage visible early. The ideal line falls steadily; a flat line warns that work is stalling. | Velocity is the average amount of work a team completes per cycle, measured in issues or story points. By tracking it over several cycles, teams forecast how much they can realistically take on next. Velocity is a planning aid for a specific team over time — never a target to maximize or a way to compare teams against each other. |
