I can understand ZBs disregard for the IT charlatans, but not his tirades against process mapping.
I'm Acn myself and as a rule tend to find that the charlatans are way too self important for their roles and generally do not have the capacity to understand the functional specitications they are supposed to be configuring.
However process mapping is very much a continuation of the high level strategy stuff. It is potentially high value work, but often the client does not have the balls to implement / or does not implement properly - at which point they call us back in again to help!
Long live process mapping!
