I report status up to upper management by showing % complete of epics. Our epics are on our project schedule according to our plan. Percent complete of an epic is defined as the number of story points accepted for stories under the epic divided by the total story points of the epic. How do I get Jira to a show me this percentage complete, and is there a tool, view, etc. that will concisely show me the progress (%-complete) of all epics within a release?
