Who participates in the SoS?

• A. Release Train Engineer, Scrum Masters, system team representative
• B. Product Management, System Architect, Agile Coach
• C. Scrum Masters, Developers, Product Owner
• D. Quality Assurance Lead, Release Train Engineer, DevOps Engineer

Answer: (A)

Scrum of Scrums is a cross-team coordination forum where the focus is on dependencies and impediments that span multiple teams. The people who typically participate are the Scrum Masters from each participating team, with the Release Train Engineer often serving as the facilitator. A system team representative is included to address integration and automation concerns that require cross-team visibility.

This setup ensures that coordination happens at the right level: Scrum Masters bring team-level impediments and dependencies, the RTE keeps the overall program alignment and timing, and the system team representative provides the technical integration perspective. Other roles like Product Management, System Architect, Agile Coach, Developers, Product Owners, QA Lead, or DevOps Engineer aren’t standard participants in the Scrum of Scrums, though they may contribute in other forums when needed.
