Risk-Based Inspection

Cost generally requires fairly detailed information to fully assess. It is possible,
although not always practical, to assign a monetary value to almost any type of
consequence. The cost associated with most of the consequences listed above
can be calculated using standard methods. Information such as product value,
capacity, equipment costs, repair costs, personnel resources, and environmental
damage may be difficult to derive, and the manpower required to perform a
complete financial-based consequence analysis may be limited depending on
the complexity of the relationship of failure to lost opportunity cost. However,
expressing consequences in monetary units has the advantage of permitting a
direct comparison of the various categories of consequences on a common basis.
Therefore, it is often better to provide approximations or “best estimates” than to
use only verbal descriptions (see 11.2.2).
