Model of Success
There does seem to be a desire to talk more about success rather than harp on about failure these days. I suppose the problem is that after an adverse event there is a need (desire) to make sense of why things went wrong and so we look at 'failure'.
A model of success, on the other hand, would need to identify opportunities for failure and then develop preventative measures. Hollnagels' barrier approach.
If we accept that everyone is trying to do a good job, then what we need to examine is the ways in which normal operations become exposed to hazards.
