Which two roles should facilitate an ART sync?

The Release Train Engineer (RTE) is a servant leader and coach for the Agile Release Train (ART), who facilitates ART events and processes, and supports teams in delivering value. The RTE’s responsibilities include facilitating Program Increment (PI) planning, where they play a vital role in the success of the event, helping the ART prepare for PI planning, and facilitating the PI planning event itself1.

The Scrum Master also plays a crucial role in facilitating ART syncs. As part of their responsibilities, Scrum Masters help their Agile teams work together effectively, and they also participate in ART events, including the ART sync2. This collaboration ensures that the teams on the ART are aligned and can address any impediments or issues that may arise.

In summary, the Release Train Engineer and the Scrum Master are the two roles that should facilitate an ART sync, as they both have responsibilities that directly involve the coordination and facilitation of ART activities.
