A Gartner research note I discovered recently called The IT Professional Outlook: Where Will We Go From Here? (from 2005) predicted that by 2011 "70 percent of leading-edge companies will seek and develop “versatilists” while deemphasizing specialists."

This diagram better shows the versatilist skills therefore:
As mentioned in a previous post I believe that we architects need not only breadth, to quite a level of depth, but also a good range of skills across all disciplines if we are to come up with new ways of thinking to solve some of the wicked problems out there. Architects should therefore by V(ersatilist), not T-shaped.
