This is because an information steward is a person or group who is accountable for the quality, integrity, and usability of the information assets within a specific domain or function1. The responsibilities of an information steward include the following1:
Defining and enforcing data quality standards, policies, and procedures
Monitoring and measuring data quality performance and outcomes
Identifying and resolving data quality issues and errors
Collaborating with data owners, custodians, analysts, and users to ensure data quality alignment and improvement
Educating and training data stakeholders on data quality best practices and tools
An information steward plays a key role in ensuring that the information assets are accurate, complete, consistent, reliable, and fit for purpose1.
The other options, information custodian, information analyst, and information owner are not directly responsible for information quality. They are more involved in the creation, storage, access, and use of information assets, rather than their quality2. They may also have different perspectives and interests than the information steward regarding the information quality. For example, the information custodian may focus on the security and availability of information assets, while the information analyst may focus on the analysis and interpretation of information assets. The information owner may focus on the value and benefits of information assets. Therefore, they may not have the same authority or responsibility as the information steward for ensuring information quality.
