Memory anchors
Effective Age
Effective age reflects condition and maintenance, not only calendar age.
RUL
Remaining useful life should reflect condition, technology, use and maintenance.
Physical Deterioration
Physical deterioration reflects wear, corrosion, damage and deferred maintenance.
Functional Obsolescence
Functional obsolescence arises from lower utility, excess operating cost or outdated design.
Economic Obsolescence
Economic obsolescence comes from external demand, regulation or market changes.
