PM is a schedule of planned maintenance actions designed to prevent breakdowns and failures. It's like changing the oil in your car every 3,000 miles because the manufacturer recommends it, regardless of the oil's condition. When it comes to equipment on the factory floor, PM is often performed whether it's needed or not. That can actually cause more problems than it prevents if the service isn't performed properly. More than 60% of equipment problems are the result of human issues, such as procedural problems, human error or training deficiency.
