A standard formula for the quantitative definition of risk is, Risk=
P
(loss)× L(loss) , where risk is the function of the probability (
P
) of loss and the significance of its consequences (
L
) (Manuj and Mentzer, 2008). Hetland (2003) and Diekmann et al. (1988), on the other hand, view risk as the implication of an uncertain phenomenon. Waters (2007) explains the difference: risk occurs because there is uncertainty about the future, which means that unexpected events may occur. Knight’s (1921) distinction between certainty, risk and uncertainty is probably the best known and most used typology of uncertainty for risk management. In his definition of risk Knight coined the terms (quantitative) “measurable” uncertainty and (non-quantitative) “un-measurable” uncertainty when there is only partial knowledge of outcomes in the form of beliefs and opinions (Vilko and Hallikas, 2012).
