This document discusses the stewardship approach to data governance. It describes how everybody who defines, produces, or uses data is a data steward. Rather than assigning data steward roles, the stewardship approach recognizes the existing responsibilities that people have. This reduces the invasiveness of data governance initiatives. The document provides guidance on engaging different types of data stewards based on their relationships to data and leveraging their existing responsibilities. It also addresses how the large number of stewards impacts the complexity of data governance programs and how best to deal with accountability.
