Kharon - Why is it you can never find a Senator when you need one. Makes me wonder if all the estimates rhetoric and inquiry recommendation are just so much egocentric hot air, feeding public image and keeping the flaccid balloon of government aloft.
Well said.
Lookleft - The first time that style of diagram appeared was in the QF1 report. It is an attempt to put the Reason model in a box and as you have highlighted it may be theoretically impressive but doesn't give a real time indication of what contributes to an accident. Like a lot of HF specialists from a cognitive psychology background they lack the practical knowledge of what happens in a flight deck.
Others have used that style of diagram effectively. See
Friendly Fire: The Accidental Shootdown of U.S. Black Hawks over Northern Iraq by Scott Snook, published in 2002. Snook used a very similar diagram to illustrate linkages between the various organizational factors contributing to the shootdown.
