Data steward

A data steward is a person responsible for the management of data elements (also known as critical data elements) - both the content and metadata. Data stewards have a specialist role that incorporates processes, policies, guidelines and responsibilities for administering organizations' entire data in compliance with policy and/or regulatory obligations.

The primary responsibility of a data steward is to provide operation team members data entry rules for entering each data element into a computer.

Data stewards begin the stewarding process with the identification of the elements which they will steward, with the ultimate result being standards, controls and data entry. The steward works closely with business glossary standards analysts (for standards), with data architect/modelers (for standards), with DQ analysts (for controls) and with operations team members (good-quality data going in per business rules) while entering data.

Data stewardship roles are common when organizations attempt to exchange data precisely and consistently between computer systems and to reuse data-related resources. Master data management often makes references to the need for data stewardship for its implementation to succeed.

Data Steward Responsibilities

A data steward ensures that each assigned data element:

  1. Has clear and unambiguous data element definition.
  2. Does not conflict with other data elements in the metadata registry (removes duplicates, overlap etc.)
  3. Has clear enumerated value definitions if it is of type Code.
  4. Is still being used (remove unused data elements)
  5. Is being used consistently in various computer systems
  6. Has adequate documentation on appropriate usage and notes
  7. Documents the origin and sources of authority on each metadata element
  8. Is protected against unauthorized access or change

Benefits of data stewardship

Systematic data stewardship can foster:

  1. consistent use of data management resources
  2. easy mapping of data between computer systems and exchange documents
  3. lower costs associated with migration to (for example) Service Oriented Architecture (SOA)

Assignment of each data element to a person sometimes seems like an unimportant process. But many groups have found that users have greater trust and usage rates in systems where they can contact a person with questions on each data element.

Examples

The EPA metadata registry furnishes an example of data stewardship. Note that each data element therein has a "POC" (point of contact).
