We use the web/cloud version of Jira and due to our ISAE certification, we have two 'done' columns on our Jira Development board. One is 'done', i.e. the developer has finished building the story. The other is 'Accepted for release', which is a status for issues that are marked by the product owner as 'releasable'. This status is obtained during or directly after a sprint demo. We also use a burndown chart that is based upon storypoint estimates. However, it only counts issues that are in the last column as 'finished' and thus deducted from the estimate. If those statuses are only obtained at the end of a sprint, the burndown is pretty horizontal, as you can probably imagine.
Therefor I was wondering if it was possible to mark two columns as a 'done' column to be used in the burndown chart?
Disclaimer: I don't have administrator rights, but as scrum master was asked to research how to more effectively use the burndown chart..
