Why Do You Need a Data Steward?

A data steward plays a critical role in handling and optimising an organisation's data assets. To begin, these employees are critical to maintaining data quality by constantly monitoring accuracy, completeness, and consistency. This leads to more trustworthy decisions and operational efficiency. Second, stewards provide substantial contributions to compliance and risk mitigation activities. They help protect the organisation from legal and financial risks associated with noncompliance and potential data breaches by remaining up-to-date on data protection laws, regulations, and industry standards. Third, their emphasis on data quality helps to reduce costs by preventing errors and inconsistencies that would otherwise result in additional costs for corrective measures and rework.

Aside from data maintenance, the steward strives to align the data catalogue with the company's strategic goals in order to contribute to more informed decision-making.

In Conclusion

A data steward acts as a manager of data, guaranteeing its quality, security, and conformity with the organisation's objectives. The work of these data managers becomes increasingly crucial, from ensuring data integrity to contributing to strategic decision-making.
