If information is the new corporate wealth, who is responsible for maximizing its value, ensuring its proper use, and safeguarding its integrity?
You might be tempted to say "well, isn't that what the CIO does?" but there's a strong case to be made that it's a very distinct role: one with unique skills and accountability.
And since we already have a well-established technology-centric role for the proverbial Chief Information Officer, there's a need to come up with a new label -- hence CDO.
I saw an excerpt from a recent book that tries to make the case for a CDO, so the meme is perhaps coming back en vogue again.
The question remains -- are the conditions right this time?
