Definition of Epics:
Epics or Epic Stories are defined as large User Stories that would be hard to estimate in this form or hard to complete within one Iteration. Epic Stories are usually not very highly prioritized and are waiting to be broken down into smaller components.
Use of Epic Stories:
Epics are often used as placeholders for new ideas that have not yet been fully fleshed out. Epic Stories are often used when working out an initial backlog. Later on, however, they should definitely be broken down into smaller user stories, which are easier to manage and where the requirements of the individual story are defined much more precisely.
Advantages of Epic Stories/ Epics:
- Epics serve as placeholders for comprehensive requirements.
- Epics can span multiple stories and organize them.
- Better overview of the entirety of all stories.
