What is SoS?

• A. System of Systems
• B. Scrum of Scrums at the program level
• C. Team synchronization mechanism
• D. Program coordinates team dependencies weekly or more frequently

Answer: (D)

SoS is the program-level coordination mechanism that brings together representatives from each agile team to surface and manage cross-team dependencies, risks, and blockers. It’s typically run on a cadence—weekly or more often if dependencies require closer synchronization—so the program can align delivery and ensure smooth integration across teams during the increment. The key idea is coordinating dependencies at the program level, not just a generic team sync or a broader System of Systems concept. While the Scrum of Scrums term describes the idea of cross-team coordination, the defining aspect here is the program-level coordination of dependencies on a regular schedule.
