But our sales would plummet!
Getting industry buy in to a never ending cost center over and above current cert requirements puts a very hard edge on "the continuous improvement model" -- for all that I agree on periodic review to get after some of those difficult trade offs that have to be made to get anything built.
(I also suspect that any analysis short comings come more from the bean counting side than the design team side ...)
