That said, it's not impossible to have named custodians. I've worked with a number of clients where they have named their Data Custodians. These have usually been smaller organisations, where there is only one subject matter expert for each system and that person has been named as the Data Custodian. (Nicola Askham)

Humans still make the decisions, but they make them more and more based on what computers tell them about commercial processes. That makes individuals such as data custodians in demand across many different industries and fields. (Techopedia)

This creates an environment where the Data Custodians have the necessary decision-making authority to respond to daily demands and issues without creating operational bottlenecks. (Central Washington University)
