Great article and a good thing. I think (based on my experience with CIO's) that they have been "performing these functions" in one form or another (albeit, not in heavy concentration) for years. It makes sense.
Personas of the Next Generation
Chief Infrastructure Officer
Chief Integration Officer
Chief Intelligence Officer
Chief Innovation Officer
The luxury of being able to focus on a single "expertise" is truly a luxury today. Executive Management is expected to multi-task, integrate, monitor, innovate and execute just like the people that report into them. I expect CIO's to surround themselves in their circle of confidence, with individuals who are fluent in these areas - reside deeper in the organization - and are the added brain cells needed to do these jobs well.
