Which role is accountable for a specific service within an organization?

The Service Level Manager is responsible for negotiating, documenting, and reporting on SLAs across multiple services, not for end-to-end accountability of any single service.

The Business Relationship Manager focuses on maintaining the relationship and communication between the IT service provider and its business customers, not on accountability for a specific service's delivery.

The Service Owner is accountable for the delivery, performance, and continual improvement of one specific service. This role acts as the primary point of accountability for that service across all service management processes, ensures it meets agreed requirements, and represents it to customers and internal stakeholders.

The Service Continuity Manager is responsible for ensuring IT services can recover within agreed timeframes after a disaster, a scope limited to continuity rather than overall service accountability.
