Scrum Burndown in Trac

Notice: This plugin is unmaintained and available for adoption.


This is a plugin to enable burndown chart capabilities, a common part of Scrum and other agile development methodologies.

This plugin is integrated with the TimingAndEstimationPlugin.

At the beginning of a sprint, after the tickets have been input and estimated in Trac an admin user should click the 'Start Milestone' plugin. This inputs a datetime integer into the milestone table to indicate when the milestone was started. The daily script will only record hours_remaining entries for milestones that have started, but have not been completed. It should be fairly obvious, then, that an admin user should click the 'Milestone Complete' button at the end of the milestone to prevent the burndown_job from continuing to collect data.

You can view different burndown charts, selectable by milestone and component by choosing from the dropdowns and clicking the 'Show Burndown Chart' button.

For this to work, it is imperative that developers keep the 'Estimated Hours' and 'Total Hours' fields accurate and up-to-date on the tickets they are working on. The 'Total Hours' field itself should never be manually edited, but rather, it can be changed by entering positive and negative values into the 'Hours to Add' field.

Questions and Answers

  1. Is there an easy way to move the start date of a sprint into the past? (For example when some tickets of a milestone already have been closed when starting a sprint, immediately after installing this plugin.)

This can be done in the administration panel, available in Trac 0.11 and higher.

  1. Is there any way to automatically grant BURNDOWN_VIEW to any/all users? It's slightly annoying to have to explicitly set that permission on every user (which in our case is about 40 people).

Any authenticated user pulls its default permissions from the 'anonymous' group, see If you add BURNDOWN_VIEW to the anonymous usergroup, everyone can view it. If you add it to the authenticated usergroup, any authenticated user will be able to view it.

Fixes #11089:

  • Renamed config.html to admin_burndown.html in order to better ensure that we'll meet the requirements that template names are unique.
  • Changed url in to point to the trac-hacks site.

Thanks to Jun Omae (jun66j5) for these fixes.

Refs #7066, #11069:

  • Removed Trac pre-0.11 compatibility code.
  • Changed module names to follow Trac naming conventions.
  • Updated source file headers and added where missing.

Note: If you enabled the plugin through the web admin, or by providing the full module name, you'll need to re-enable the plugin or edit the [components] section:

burndown.burndown_admin_milestones.burndownmilestonesadminpanel = enabled
burndown.burndown.burndowncomponent = enabled


burndown.admin.burndownadminpanel = enabled
burndown.burndown.burndownmodule = enabled
