In Jira, an epic is a large body of work that can be broken down into smaller tasks, commonly referred to as "issues" or "stories." Epics are used to organize work within a project, grouping related tasks that collectively contribute to a larger, overarching goal. An epic typically spans multiple sprints and involves various aspects of a project, such as development, design, and testing phases. This categorization helps teams to better manage their workload by aligning and tracking the progress of related activities more efficiently. Epics provide a high-level overview of the work involved, allowing project managers and teams to estimate timelines and resources more accurately and to ensure that all related tasks are completed in a coherent and timely manner.
