The Service Owner is accountable for a specific service, ensuring it meets the needs of consumers and delivers the agreed-upon value. This accountability includes overseeing that all activities related to the service, including deployments, are aligned with the overall value stream and contribute to the desired business outcomes. While other roles participate in the deployment process, the Service Owner holds the ultimate responsibility for the service's value proposition, making them the primary role for ensuring this alignment.

A. The Service Desk Manager focuses on user support and incident management, not the strategic alignment of deployments with value streams.

B. The Change Manager (or change authority) focuses on managing risk and authorizing changes, not the end-to-end value delivery of the service.

D. The Release Manager coordinates and oversees the release of new or changed services, but the accountability for the service's value rests with the Service Owner.
