Which chart is used to forecast completion by showing remaining work over time?

• A. Gantt Chart
• B. Burndown Chart
• C. Control Chart
• D. Histogram

Answer: (B)

A burndown chart is designed for forecasting completion by showing remaining work over time. On the chart, time is along the horizontal axis and the amount of work left (such as story points or hours) is on the vertical axis. As the team completes work, the remaining work drops, producing a downward line that helps you predict when everything will be finished if the current pace continues. This makes it a go-to tool in Agile workflows for tracking progress toward a sprint goal and spotting whether adjustments are needed to meet deadlines.

Gantt charts map out tasks, durations, and dependencies, not the remaining work over time. Control charts focus on process stability and variation, not forecasting overall completion. Histograms display the distribution of data, not the forecast of remaining work.
