Configure domains, roles, and permissions to implement centralised/decentralised/federated models, with a roles×domains matrix that decouples functions, maintains traceability, and propagates capabilities in a multi-level/multi-domain approach. An integrated BPM orchestrates approvals/notifications by role and applies policies on the metamodel lifecycle (states, transitions, validations), with integrable notifications (e.g., email) under governance-first/by-design principles.
