Some time ago (1987) Professor Shaun Tyson produced the following prediction: Personnel work can be seen to be subject to conflicting and powerful pressures which are leading to the balkanization of the personnel role. The territory which could once have been delineated as personnel country, is being invaded, sold-off, subdivided and put under lease to consultants, sub-specialists and line managers, whose crosscutting alliances do not correspond to a coherent, separate function. 

To what extent has this happened since then? If not, what has happened?
