Here he speaks about the difference between BIM Manager and CAD Managers which I can fully relate too having being a CAD Manager and now a BIM Manager.
The differences are huge! As a CAD Manager you managed the day to day operation of CAD, the CAD standards, set-up, file management, deployment, etc. This was a full time job.... however I was rarely involved with managing the projects side of things.
What I have found as BIM Manager is I now have more to do with collaboration with consultants and clients rather than the set up and operation of Revit. My Revit users know what they're doing, I'm more involved with the managing of the project rather than the management of the software.
Dont get me wrong, I still set up BIM standards, educate, and develop processes as well as evaluate BIM related software, but my role and duties are no longer confined to the operation and maintenance of the software as it once was as a CAD Manager. As a BIM Manager it's now more project related as well as managing and informing the company as a whole on BIM related issues.
The CAD Manager is Dead... Long live the BIM Manager.
