Burndown Chart

Summary of Burndown Chart

Burndown Chart answers your question, "Can all tasks be completed by the due date?" at a glance. Burndown Chart plots "the amount of tasks" vertically and "time" horizontally and shows tasks left to do versus time. As time pass, the outstanding tasks decreases. The lines in the graph lean from top to bottom and from left to right. There are 3 lines in the Burndown Chart.

  • Actual Line : This line shows the actual result of the progress and the currently outstanding tasks. The "estimated hours" will decrease as tasks are completed.
  • Estimated Line : This line shows the estimated progress. It is calculated from "Due Date" and "Estimated Hours". Actual Line overlaps Estimated Line when the tasks are completed as planned.
  • Ideal Line : This line is drawn by averaging the amount of tasks by the number of days. This line can be used to verify if the plan is appropriate.

Set Span

The span of Burndown Charts depends on milestones. On milestone settings, set "Start Date" and "Release Due Date (Finish Date)". Long spans tend to cause delay in changing plans. The ideal span is around 1 week to 1.5 months. When the span is set, currently active milestone's Burndown Chart will be displayed on Project Home.

Add Information to Issue

When new issues are added with "Milestone", "Due Date" and "Estimated Hours", the data will be added to Estimated Line. If the "Estimated Hours" is left blank, it will be calculated as 1 hour. To create an accurate Burndown Chart, please enter "Estimated Hours" whenever possible. Actual Line declines as much as "Estimated Hours" when an issue is completed.
