P-F Curve "A new and old look"

Updated: Oct 23, 2021

Many people think that there is only one P-F curve that describes an asset's decline; however, there should be one for every failure mode and mechanism for each functional failure. This means we may need to evaluate as many as 10 or more curves, each with their own Point "P". Also, P isn't the point where a "defect is detectable", but rather the point at which we consciously decide that "failure is imminent". We may have been watching the mechanism for months, but now say that action must be taken to prevent Functional Failure.
