These internal consultants are some of the folks currently in IT, HR, OD, T&D or their more capable replacements. I also think that much of the process-sharpening can be done by the workers/contributors and fewer support staff or managers will be needed.

There's an awful lot of good practical "stuff" around, mostly from the 80's, on the whys, hows and wherefores of self-directed work teams. Much of it is pertinent to the opportunities in today's environment for IT, HR, OD, T&D and line management (and the knowledge workers themselves) to work together towards effective adaptation.
