Scrum of scrums is a SAFe program-level event that is geared toward synchronization between scrum masters of the Agile Release Train; it’s facilitated by the Release Train Engineer.
It is a scaled-up version of the team’s Daily Standup.
At least once a week, SMs provide update to the group. Updates on:
1) Accomplishments since the last SoS
2) Goals between now and the next SoS
3) Current and any foreseen Impediments between now and the next SoS
