I read all the above. However, MCAS was not designed by bean counters, or indeed anyone from Chicago. They would not have a clue about where to start; they probably don't possess a CAD station among all of them, and MCAS is entirely about aerodynamic characteristics. It was designed and checked and had test plans written by aeronautical engineers, no less, from Boeing. I suspect some detail elements would be subcontracted out, possibly even to the low bidder, but the short list preparation and selection would be done by aeronautical engineers.
Now the engineers may not have co-ordinated themselves adequately, and the various changes to MCAS characteristics during it's development may have been garbled along the way. But that wasn't bean counters who did the lack of liaison, was it ...
