I am looking for input on PdM specifice KPI's not the ones used at the Reliability Program level, but PdM specific. Some of what I look at are:

Cost Savings of PdM find vs. run to failure.

Pdm Program efficiency which is the Pdm program costs/total cost savings. (percentage)

Lost production ratio which is a ratio of time to perform total replacement vs time to repair.

Cost efficiency which is cost savings/cost of replacement if run to failure.

Cost per data point which is all program costs including training, travel, equip amort, manpower/ avg. number of data points. This one is kind of out there but was requested.

What do some of the rest of you do to justify your existance?

Perhaps you are looking for the same thing as this gentleman in the relaibility forum:

Not really, but the lack of response to the posting in this portion of the board tells me that most likely a lot of people are not really measuring the effectiveness of their programs.
