Isn't that true of most CxOs? I've always read CxO as “the corporate officer who is the chief of x” (well, with a special case for CEOs who are the chief of everything rather than the chief of executive.)

Director of Technology

Information Technology Manager

VP of IT

VP of Ops

VP of Eng

Engineering Manager

--

They are all "technology Officers" who report to the Chief of Technology - where Technology is a broad umbrella covering all things not HR, not Business-Specific, not Sales, etc...

It is an apt title.

It's just a label that everyone understands.
