Correct answer & explanation
✓
The Release Train Engineer (RTE).

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The Product Management team.
Why it's wrong here
Product Management typically facilitates the PO Sync, which focuses on content and priority. While they may attend the Scrum of Scrums, they do not facilitate it, as the SoS is primarily concerned with the process and execution aspects handled by the Scrum Masters and the RTE.
- ✓
The Release Train Engineer (RTE).
Why this is correct
The RTE facilitates the Scrum of Scrums to ensure that all teams on the ART are aligned and that any cross-team impediments are being addressed. They use this time to gather status, manage risks, and ensure the train is moving toward its PI Objectives collectively.
- ✗
The System Architect.
Why it's wrong here
The System Architect provides technical leadership and guidance but does not facilitate the synchronization of the Scrum Masters. Their role in the SoS is usually to provide input on technical blockers or architectural changes that might impact the teams' ability to deliver their objectives.
- ✗
The Business Owner.
Why it's wrong here
Business Owners are stakeholders who provide the business context and value assessment. They are not involved in the day-to-day process synchronization of the Scrum Masters. Their primary interaction with the ART's execution is through the System Demo and high-level progress updates from the RTE.
