I've been with my team for about 2yrs now and I'm noticing that the epics aren't sufficient for easily identifying where we are focusing our development efforts on our products. Especially as I calculate ROI for different feature development, or trying to identify where we spent time improving the user experience. I want to get more granular, but either I'm not using epics efficiently, or I need to leverage another tagging tool in JIRA to pull that kind of data. I'd love some thoughts!
