Which role is most associated with facilitating governance, interfaces, and dependencies during ART release planning?

• A. Product Owner
• B. Architects and UX
• C. Business Owners
• D. Release Train Engineer

Answer: (B)

Governance of how the solution is built across multiple teams, along with defining the interfaces and managing cross-team dependencies, is led by the architects. The architects (System Architect/Engineering) define the architectural runway, set interface contracts between components, and coordinate enablers and integration points that span teams. This role ensures that what teams plan to deliver can actually be integrated smoothly, meeting architectural constraints and reducing risk across the ART. UX attention to user interactions complements this by ensuring the interfaces are usable, but the primary ownership of cross-team governance and interfaces rests with the architects. That’s why this option best fits the question.
