Design Domain → Enterprise Architect(s), Data Steward(s), Process Owner(s), Platform Owner
Foundation Domain → Enterprise Architect(s), Platform Owner
Portfolio Domain → Service Owner(s), Platform Owner
Technical Domain → Technology Service Owner(s), Application Service Owner(s), Platform Owner
CSDM governance requires the correct domain owners because each domain represents a different type of data accountability. The Design Domain is architecture-heavy and requires Enterprise Architects, Data Stewards, Process Owners, and the Platform Owner to ensure planning data is accurate and aligned. The Foundation Domain depends on shared platform reference data, so Enterprise Architects and the Platform Owner are key stakeholders. The Portfolio Domain is concerned with service ownership and service portfolio accountability, so Service Owners and the Platform Owner are the primary governance roles. The Technical Domain governs operational service and application service data, so Technology Service Owners, Application Service Owners, and the Platform Owner are needed. This division prevents one team from owning all CSDM data incorrectly and creates clear accountability.
