IT Strangled by Overspecialization
Now look at what we've done. Knowledge is so decentralized we must invent new roles to act as liaisons between all the IT groups. Architects now hold much of the high-level "how it works" knowledge, but without knowing how any one piece actually does work. In organizations with more than a few hundred IT staff and developers, it becomes nearly impossible for one person to do and know everything. This movement toward specializing in individual areas seems almost natural. That, however, does not provide a free ticket for people to turn a blind eye.

Often, the person with a certification in using the new application only really knows how to run that application.

And besides, everything else in the infrastructure is run by people who specialize in those elements. Everything is taken care of.
