What is the difference between "Epics" and "Features" in SAFe?

The distinction between "Epics" and "Features" in the Scaled Agile Framework (SAFe) is articulated precisely in the choice indicating that epics are large initiatives that can be broken down into features, with features being more focused on value delivery.

Epics are significant work items that encompass sizable business initiatives or solutions that typically require collaboration across multiple teams and may span multiple Program Increments (PIs). Due to their scale and complexity, epics are often high-level requirements that need to be decomposed into smaller, more manageable pieces.

On the other hand, features represent specific services or functionalities that deliver noticeable value to the end user and can be delivered within a single PI. They are the product of breaking down epics into tangible components that teams can work on. This structure allows for a clearer focus on delivering value and ensures that the development process can be monitored and adjusted more effectively.

This hierarchical relationship between epics and features is fundamental in ensuring that large strategic initiatives are aligned with practical, incremental delivery of value in the SAFe framework. This breakdown also facilitates planning and prioritization at different levels of the organization, ensuring that all teams work cohesively towards a common goal.
