4.1 Risk tolerance
Risk tolerance encompasses corporate tolerance and social acceptability. It
is shown in the Prioritization & Display
box in the top right corner of Figure 2.
Beside an initial risk ranking based
solely on risk magnitude, risks can also
be plotted on a probability versus cost
diagram. The cost of the consequences
is derived from the right column of
Table 1, Zone of Influence. The curve of
probability versus cost is compared to a
risk tolerance curve. In this study, this
latter curve was specially developed
for the client. Societal acceptability
was also considered, as developed for
different industries. In some cases, a
so-called F-n curve can be used.
The plot showing risk and tolerance
allows the analysis to:
* prioritize risks based on their
intolerable part, which focuses
attention on those risks that actually
have the potential to hurt people;
this enhances the focus and the
value of the assessment;
* determine which risks are:
a) tactical, i.e. which are under the
responsibility of the management;
b) strategic, i.e. which might require
upper management to shift
its objectives.
Depending on the goals and on the
detail level of the study, tolerance
thresholds can be developed (Oboni
and Oboni, 2016a). Then again, for simplified screening level approaches, the
owner of the portfolio may be satisfied
with a simple risk ranking or risk dashboard. However, it will be noted that
tolerance-based prioritization tends to
focus management attention on risks
