Final answer:
A burn-down chart shows the remaining work over time in a project or sprint, helping to track progress and make adjustments.
Step-by-step explanation:
A burn-down chart is a graphical representation of the remaining work over time in a project or sprint. It shows how much work is left to be completed and how the team is progressing towards completing the project or sprint goals. The chart typically includes a horizontal axis representing time and a vertical axis representing the amount of work remaining.
The burn-down chart does not show team member performance, completed tasks in a sprint, or sprint velocity. It is primarily used to track and visualize the progress of a project or sprint and make adjustments accordingly.
