A data steward is a subject matter expert who is responsible for defining and maintaining the integrity of a specific type of data or data domain1. They help the organization build data glossaries, create and maintain data quality rules, and determine who has access to data1. Data stewards also work closely with any system of record to ensure proper controls are in place and are maintained to ensure the data produced is of high quality2. Therefore, if the IT department has determined that problems with a business report are due to quality issues within a set of data, they should refer the matter to the data steward for resolution. References := CGEIT Review Manual, Chapter 3: Benefits Realization, Section 3.2: IT Value Delivery Processes, Subsection 3.2.4: Data Quality Management, Page 103.
