What is the difference between burndown and burnup chart?

Burndown Chart Overview

A burndown chart tracks the amount of work remaining in a sprint or project over time. It typically displays the remaining effort on the vertical axis and time on the horizontal axis. The goal is to visualize progress toward completing the work by the end of the sprint. As tasks are completed, the line on the chart trends downward, ideally reaching zero by the end of the sprint.

Burnup Chart Overview

A burnup chart, on the other hand, shows the amount of work completed versus the total amount of work required. The vertical axis represents the total work, while the horizontal axis shows time. This chart includes two lines: one for completed work and another for the total work. As work is completed, the completed line trends upward, providing a clear view of progress and scope changes.

Key Differences

• Focus: Burndown charts focus on remaining work, while burnup charts emphasize completed work.
• Scope Changes: Burnup charts easily reflect scope changes, as the total work line can adjust, whereas burndown charts may not show this clearly.
• Visual Representation: Burndown charts trend downward, while burnup charts trend upward.

When to Use Each Chart

Burndown charts are effective for monitoring sprint progress and ensuring teams stay on track. Burnup charts are beneficial for tracking long-term projects and understanding how scope changes impact progress. Both charts serve unique purposes and can be used together for a comprehensive view of project performance.
