Data governance, stewardship and management are more often than not mentioned in the same breath but are all three the same? If not, what is the difference between the three? How to determine what function belongs to which area?
All three are closely related often with blurring boundaries and sometimes have overlapping functions and at the very least need to work closely with each other to reach their end goals. But still there is a need to understand the basic difference between the three to be able to perform whatever role you have, more effectively. Based on my understanding I will layout what each means and how they are related to each other at a very high level.
Data Management, I believe, encompasses the broadest scope of the three - governance and stewardship being the sub-functions. It encompasses everything related to the data that an organization has – right from definition, delivery, quality to security and access. As per DAMA Data Management Body of Knowledge (DAMA-DMBOK):
"Data management is the development, execution and supervision of plans, policies, programs and practices that control, protect, deliver and enhance the value of data and information assets.”
