Example 1:

A system is established to determine the likelihood of an impact occurring and the severity of the impact. Numerical values are assigned to each of these.

Likelihood of Impact:

Severity of Impact:

The figures can be on any scale.

The determination of significance will then be assed using a multiplication:

Likelihood x Severity

There are generally two methods of determining significance:

1.         A figure is chosen and anything with a score above that is significant, anything with a score below it is not.

2.         A matrix is used, as demonstrated below:
