 ## Use cases
 
 - Suppose your team is working on a large feature that involves multiple discussions throughout different issues created in distinct projects within a [Group](../index.md). With Epics, you can track all the related activities that together contribute to that single feature.
 - Track when the work for the group of issues is targeted to begin, and when it is targeted to end.
-- Discuss and collaborate on feature ideas and scope at a high-level.
