In the SAFe work item hierarchy, Features are decomposed into what?

In the SAFe framework, Features are significant pieces of functionality that deliver value to users and customers. These Features are typically formulated at a higher level and subsequently broken down into Stories, which are more granular and actionable items used by Agile teams during their iterations.

Stories are specifically designed for implementation by development teams, and they focus on delivering functional increments of the Feature. By decomposing Features into Stories, teams can ensure that they have a clear understanding of the specific requirements and can prioritize work effectively. This breakdown facilitates agile planning and delivery, enabling teams to manage and iterate on their work in shorter cycles, thus delivering incremental value.

The other options do not align with the hierarchical relationship established in SAFe. Spikes refer to research or exploration tasks, Tasks are specific pieces of work that may be derived from Stories, and Enablers serve to support the development of Features but do not directly decompose them. Hence, Stories are the appropriate decomposition of Features in the SAFe work item hierarchy.
