Thanks for the clarification. I like the toast example. ;) Rob

Cases where the changes are complex or could destabilize the trunk but don't span more than a few JIRAs probably don't need an Epic. For example, I see you've been working on adding Kerberos authentication to Ambari (awesome!) ... In this case, you might not have needed an epic if the work was only going to span a few different JIRAs. Since it did deal with logging into Ambari, a mistake here could render Ambari unusable, so its good to make your changes in a feature branch to test. With that said, using an epic to track and group child JIRAs certainly helps with the organization. In the case where you have an epic, yes, you are correct. The child JIRAs would be the commits you see on the feature branch. And when you successfully merge back into trunk, you can close the epic. For example, let's say you had an Epic where Ambari needs to make toast. You'd have this in JIRA: AMBARI-1 - Implement Toast Making AMBARI-2 - Slice Bread AMBARI-3 - Buy Toaster AMBARI-4 - Magic AMBARI-5 - Unit Tests for Making Toast You feature branch would be called branch-feature-AMBARI-1 and would contain these commits: AMBARI-2 - Slice Bread AMBARI-3 - Buy Toaster AMBARI-4 - Magic AMBARI-5 - Unit Tests for Making Toast When you merge back in, each child JIRA appears on trunk. The master Epic, AMBARI-1, does not, and can now be resolved. > On Sep 26, 2016, at 9:38 AM, Robert Levas <[email protected]> wrote: > > Jonathan… > > Thanks for the wiki page. This is great.
