You did good. Robert Dewar's experience may be different, but
in 32-odd years in the business and a great deal of DoD, NASA,
and ESA involvement, I've never seen a large cyclic-executive-
architecture system that was in any way successful.
The trouble is that cyclic-exec projects are easier for bad
managers to manage. They don't have to understand tough
concepts like deadlock, critical sections, rate monotonic
scheduling, etc.
Boeing management had to be convinced? I hesitate to ask,
but how is the 777 avionics s/w structured?
