HKSM

A chart that displays how much work remains against the time left in a timebox, typically updated daily.

Key Points

• Plots remaining work (e.g., story points, tasks, hours) against days in the iteration.
• Helps assess if the team is on track to finish by the end of the timebox.
• Often includes an ideal trend line; the actual line may rise if scope is added.
• Updated frequently to promote transparency and guide forecasting and decisions.

Example

A Scrum team plans 120 story points for a 10-day sprint. Each day, they update the burndown chart with the remaining points. Mid-sprint, 10 points are added, and the actual line bumps up, signaling increased scope. The team replans to ensure the most valuable work still finishes by day 10.
