Day 27 ... stay at home. I have both Jira and Confluence at home for a year now... got trello earlier. Going forward, will cover these three tools vis-a-vis SAFe and a case study or two.
Jira is really killing the Agile world... an Epic in Jira is a Feature in Agile. In Agile, an Epic is decomposed into Features! Really messed up. So... be careful... best to provide a mapping of artifacts between Agile and Jira... before teaching SAFe to people who are using Jira.
