In order to properly breakdown and categorize work, our team would like to use a higher level issue type, such as Business Increment (BI). This would contain multiple epics which would in turn would contain multiple stories. I'm trying to understand how we could link epics to BIs in much the same way we link stories to epics. Our overall solution would include a three tiered structure where each tier could link to the one above it. Has anyone successfully implemented something similar on JIRA server?
What we've done so far:
We've tried to utilize sub-tasks/stories/epics, however the limitations on this include an inability to visualize sub-tasks on JIRA board and backlog the same way we currently view stories.
