I note with interest your suggesting that information technology increases tempo.

Research done in the UK shows this to be very much in doubt. In WW2 Divisional HQs were much smaller, and did things far quicker using less people and resources. My understanding is that there is substantial evidence from both the UK and Sweden that higher levels of information actually slow down decision making and thus tempo.

It has been further suggested that what increases really increased tempo is small thoroughly trained Divisional and Formation staffs. Not sure if this helps, but I can forward you a thesis that deals with this if you are interested.
