Master Data Governance (MDG) is the systematic management of an organization's key data assets to maintain their accuracy, consistency, and reliability. It encompasses the creation and enforcement of policies, procedures, and standards to ensure that master data—such as customer, product, and supplier information—is properly maintained and utilized. Effective MDG provides a unified and trusted source of critical data, enabling businesses to enhance decision-making, streamline operations, and adhere to regulatory standards, thereby driving overall business success and competitive advantage.
