Roles and Responsibilities Related to Data

Roles and Responsibilities Related to Data is the organizational framework that assigns legally defined and operationally necessary accountability for how personal and organizational data is collected, processed, protected, and governed. The framework distinguishes four primary designations: (1) Data Controller — the legal entity that determines the purposes and means of processing personal data, bearing ultimate regulatory accountability; (2) Data Processor — a third party that processes data on behalf of, and under instruction from, the Controller; (3) Data Protection Officer (DPO) — an independent, designated expert who monitors compliance, advises on data protection obligations, and serves as the contact point for data subjects and supervisory authorities; and (4) Data Steward — an operational role responsible for data quality, metadata management, and business-rule enforcement within a specific domain. Additional roles include Data Owner (the business-side accountable for a data asset), Chief Privacy Officer (CPO, a strategic C-suite role), and Vendor Privacy Manager (accountable for executing and maintaining Data Processing Agreements with third parties). These roles may be held by different individuals, consolidated in smaller organizations, or distributed across a federated governance model.
