We define our levels of service at an organizational level to ensure that everyone can clear the bar every time
Hmmm... that sounds suspiciously like we need to cover for people in the organisation that don't know what they're doing. Mind you, since only about 25% of people that work in IT do actually know what they're doing I guess we shouldn't rock the boat, should we?
Seems to contradict the point made that teams need "to hear about their mistakes if they are ever to learn from them". IMO, if useless members of staff could be identified because they were not allowed to hide behind organisational process then we would really create winning organisations.
