In the Hierarchy of User Stories, what is a Theme?

In Agile methodologies, a Theme is a collection of related User Stories and/or Epics. Themes help to organize and manage work at a higher level, grouping related stories and epics together to ensure that the development efforts are aligned with broader business objectives or goals. This hierarchical structuring allows teams to see how individual user stories fit into larger business initiatives and ensures that the work is aligned with the overall strategy. By using Themes, teams can manage complex projects more effectively, ensuring that related functionalities are developed in a coordinated manner.
