Problems that can occur with ungoverned master data include data inconsistency, redundancy, and inaccuracies. Without proper governance in place, different departments or individuals within an organization may create and update master data without coordination or communication. This can lead to duplicate or conflicting information, making it difficult to trust the accuracy of the data. Inconsistencies in naming conventions, data formats, and definitions can also arise, causing confusion and hindering data analysis and reporting efforts. Additionally, ungoverned master data can make it challenging to comply with regulatory requirements and impede data integration efforts across different systems and applications. Overall, the lack of governance for master data can result in decreased data quality, efficiency, and decision-making capabilities within an organization.
