Design and operate the cross-functional AI governance service model with explicit inputs, accountable owners, service expectations, decision rights, handoffs, escalation paths, and review cadences across Security, Privacy, Legal, TPRM, business relationship management, Data, Engineering, product teams, and Internal Audit; preserve independent control authorities and ensure delivery teams do not approve their own risk acceptance. The role maintains the AI inventory and risk-tiering model, directs lifecycle assessment and monitoring, translates healthcare, audit, NIST, ISO, accreditation, and regulatory expectations into operating controls, and produces timely, auditable decisions and readiness evidence.
