      I finally got around to reading it and it’s an interesting paper, does suffer just a little from some fairly obvious axe grinding but interesting nonetheless. Would be interesting to try and model the mentioned case studies using Nancy Levesons techniques


        I’ve just started reading her work on “Engineering a Safer World.” I’m not far enough into it to comment yet. What I’ve read about systems analysis thinking in aviation is that it’s meant to be “predictive.” In other words, going beyond the “proactive” flight data analysis into a newer form of safety. I think it’s also meant to include quality improvement as well. Right now I’m thinking being predictive may be impossible. For example, why not apply it to the stock market and make a fortune? In any case, I need to learn more about it.

        I see her work as part of a more general paradigm shift in system safety, we talk a good game but when our tools (like fault trees and FMEAs) are determinedly reductionist exactly how much ‘systems thinking’ are we doing? Nancy’s taking an open systems/cybernetics approach and developing toolsets to support that as I see it.
