All risk approaches assign two dimensions, namely, the uncertainty, where the risk is related to something
that has not happened yet and the effect on business objectives (or the project ones). The specific literature states
that risk is a measurable form of uncertainty, in opposition to the immeasurable uncertainty. Accordingly, the notion
of probability appears as the demarcation between risk and uncertainty and the risk is considered as representing the
situation in which the decision maker has three advantages: knows the structure of the problem; understands and
defines the range of possible consequences/outcomes; has the objective capacity to assign each outcome some
probabilities of occurrence.
