Having reread your question, you were asking about the
difference between Data Management Governance and Data Governance.
Can't say I have ever heard of it referenced to as Data Management
Governance. Would be intrigued to see what response you get. On a
linked note - Would you recommend DBOK 2.0?
In my mind, there are significant differences between Data
Management and Data Governance.
I see data management as being the the operational activities,
and data governance being the strategic and tactical approach to
assessing the data management process. Data Governance would be the
design of an an approach whereas Data Management would be the
delivery of a process.
Thinking about how this exists within a business, I have
always found that data governance best sits as a singular
entity at a corporate/enterprise level and is federated down to the
relevant parts of the organisation, with data stewards sitting in
the business, but with a dotted line up to
the corporate/enterprise level. One data governance
approach may serve many data management processes. These
processes need to be separate and different to best serve
their specific customer need, but they share the higher level
commonality via frameworks, principles, policies and
assurances practices. For smaller organisations, the 'data
governor' and 'data manager' may be the same person, but very much
as a double hatted role and with clear separation of roles and
In keeping the two processes, and roles separate, we avoid data
management becoming self serving.
I recently read a good article on Jeff Bezo's "Day 1"
There was a useful quote:
"it becomes easy to rely on process rather than the
result. In that case, the process becomes "the thing". When that
happens, sometimes companies stop looking at outcomes and only
consider whether they have followed the process correctly, not
whether the desired outcome was achieved."
As always, tailoring is the key to getting data governance
and data management right. What is right for one organisation, may
not be right for another. Rather than 'the right approach' we need
'the right approach for our business'.
