On a similar note, about 15 years ago when the Telcos got really serious about dumbing down, a thesis that all work can be described as a series of processes was accepted by the Bean-Counters and force-fed throughout the companies. As I recall it was, pathetically, called re-engineering.
The concept was that by having the experts write the processes, then new, much lower paid employees could then do the same work by following the processes and the higher paid people could be eliminated.
