My organization uses Jira to track development work. We create Roadmaps for leadership to track progress. Jira Epics and linked to the Aha! Epics on said Roadmaps. Occasionally we will have one Jira Epic that will relate to multiple Aha! Epics in different initiatives. Due to the limitations of Aha! a single Jira Epic can only be linked to one Aha! Epic.
