14.5.1 An Example of Results Display
As an example, we will look now at ORE results for a portfolio of 15 dams located
in Canada (Oboni and Oboni 2017; Oboni et al. 2019), displayed in a different way.
Figure 14.4 is a probability-consequence graph where the 15 dams (aggregated
risks per dam) have been plotted together with the corporate risk tolerance defined
with the client and with Whitman’s tolerance (Whitman 1984).
Figure 14.5 shows the same portfolio, but this time in terms of the intolerable
aggregated risks for the dams above tolerance, and their relative percentage against
the total intolerable risk of the portfolio.
It becomes immediately evident that two dams (9 and 12) represent together 99%
of the intolerable risk of this portfolio, and (see Fig. 14.4) Dam 3 requires specific
attention because it is corporately tolerable, but societally intolerable.
Tolerance

risk tolerance and Whitman’s societal thresholds (see Fig. 13.2)
