To the optimists, good luck!
We are talking "cultural change" here. Anyone with any experience of trying to implement said change knows how hard it is.
Even if Boyd and Skidmore have the best will in the world, and they probably have, they have no hope of achieving anything other than window dressing without wielding a pair of very bloody axes - and this they cannot do.
I have written on this before on Pprune, my advice is that without cataclysmic upheaval at CASA nothing will change. My guess is that by the time Messrs Skidmore and Boyd realise that they have been played (if they ever do) and the axe is required, their time will be up.
If they really really want change at CASA, better confess to PM & C, they have experts (or did have) who know how to do it so well that the target bureaucrats don't even realise they have been beheaded until they try to twist their necks.
Nothing less than breaking up CASA and reassembling its components differently will fix it in my opinion.
