Challenging the P-F “Curve”
Let me get right to it. I don’t think the P-F curve is really a curve anymore. Rather it is more like a cliff. We march right up to the edge with all our preventive maintenance activities and the equipment fails anyway. No gentle path downwards to follow, giving us lots of time to head off trouble. No, things simply go bad very quickly. The idea is to avoid the cliff. Stay back a safe distance and enjoy the view vs. extending your toes over the edge for a thrill.
