3.2 Data Governance: Ownership, Quality and Accountability

Data governance provides the structure organisations need to use information consistently, securely and confidently. This lesson explains how policies, roles and processes clarify who can access data, who is responsible for its quality and how information moves through the organisation. It explores three key foundations: clear ownership, a shared data dictionary and data lineage, which allows information to be traced back to its source and transformations. You will also learn how role-based access controls help manage permissions, why validation rules and audits support data quality, and how governance contributes to ongoing compliance. The lesson highlights a common misconception: data governance is not simply a technology project. Tools can support the work, but effective governance depends on people, accountability and shared standards. It concludes with a practical approach to implementation, starting with high-risk domains such as customer, financial and product data before expanding the framework across the organisation.
