I have been aware of NAT for some years now, so I don't think there are any comments I would want to make on the paper. I'm just disappointed that I cannot be at the symposium to meet you.
What I would have asked, given the opportunity, is for your opinion on what else is important when considering how to deal with the engineering of complex systems? Yes, NAT has an important role, but what should be alongside it?
