Non financial impact rationale

Answer: The point here is to explain about feelings and perceptions. If the persons involved in the analysis do not reach a consensus about the impact value for a specific situation, but they agree that the situation is significant enough to be taken into account together with situations for which they can determine the value, then you may have a situation where a non financial impact may be greater than any financial impacts they found related to other situations considered.

For example, in a plane crash situation, the value of the airplane can be determined, but what about the value of human lives? Someone may argue that he has a formula to calculate the value of a life, but the value may be questioned by relatives (which feelings may not be measurable), or employers (that may argue about the potential deli veries the professional would deliver to the company), making impossible to reach a consensus, but all of them would agree at certain point that the value of life is high.
