I gave a presentation at the second Resilience Engineering Symposium on November 6th, 2006. The accompanying article was included in the book, Resilience Engineering: Remaining Sensitive to the Possibilities of Failure, E. Hollnagel, et. al, editors (Ashgate Press), 2007, under the title “Unexampled Events, Resilience, and PRA”.
The words of the presentation have remained the same, but for the changing of “unexampled” to “unforeseen”, and “PRA” to “risk assessment”; the example given in slide #32 has been changed from the Storm King Mountain fire to the hydrogen explosion at Fukushima Daiichi Unit #1.
I have changed the images to reflect the recent events in Japan.
