The discipline and ongoing work methods that ferret out small or underlying problems before they morph into massive ones separate great reliability engineers from good ones, creating successful MRO maintenance reliability programs. The author of this interesting piece from Reliability Web uses the metaphor of a lemon; sometimes you need to cut it open before going any further with a recipe.
There are five habits that can help engineers, from properly identifying issues to understanding them, finding alternatives, reviewing data, and facilitating implementation of new equipment or methods.
But one of the most important practices within these habits is truly understanding the root causes of plant issues.
For example, to diagnose a machine that is breaking down because of too much vibration, it’s important to understand the chain of events leading up to that point. The machine might be vibrating too much because it’s not properly lubricated. It may not be lubricated properly because the oil is contaminated. And, finally, the root cause may be established as the storage of the oil containers outside (allowing rainwater to contaminate the oil.) Digging deeper isn’t easy but it always pays off!
