CTO vs CIO vs CDO
I can not agree more with Mike Guggemos' staement:
"When I look at what most CDOs do, at least those with whom I've interacted, they're actually doing the board-level responsibility of a CIO, which tells me that people are being hired to fill skill gaps that the CIO lacks," said Mike Guggemos, CIO of global technology solution provider Insight Enterprises. "Last time I checked, IT stands for Information Technology, and the CDO is all about how that information is processed and used."
I have been talking to different SIGs about this for quite a while now.
I think that CIOs need to go back to the basics and regain control over business information as their primary responsibility while CTOs should be responsible for technollogy component. This would also help to promote Business Information as a first class corporate asset.
