This design assumes a centrally governed enterprise platform where AI delivery, approvals, and runtime operations remain within on-premises boundaries for control and compliance. Ownership is consolidated with a platform team enforcing strict lifecycle discipline, while consumption is mediated through controlled enterprise interfaces. Governance is anchored through directory-led identity and approval workflows using Active Directory and Service Now CMDB to ensure traceability and policy enforcement. The operating model prioritises controlled promotion and auditable execution over decentralised experimentation.
