“Where CMMS Fits Into Your Reliability Journey”, an eMaint Best Practices Webinar hosted by Joel Levitt of ReliabilityWeb, discussed reliability functions that are only possible with accurate, complete and defect-free CMMS data. During the presentation, Levitt asserted that “CMMS is the hub that holds the spokes of your wheel, or reliability effort. Everything revolves around it.”
The concept of reliability changes from business to business. No one definition is correct because reliability needs change from one business to the next. However, personnel in charge of a reliability program should have a clear answer to what reliability means to them. This article helps define what reliability means to an organization, shows where flaws can develop in the program, explains how reliability responds to evolving business needs and demonstrates how lean principles can relate to these processes.
The Greek physician Hippocrates (c.460 BC – c.370 BC) is credited with an oath that was meant to provide certain ethical standards a physician was to uphold. While maintenance is not of the magnitude as being a doctor, organizations would do well to apply portions of the Hippocratic oath to their maintenance practices. Two such examples are: “…to teach them this Art, if they shall wish to learn it, without fee or stipulation; and that by precept, lecture, and every other mode of instruction, I will impart a knowledge of the Art to my own sons, and those of my teachers, and to disciples...” and “I will follow that system of regimen which, according to my ability and judgment … and abstain from whatever is deleterious and mischievous.”1 This article focuses on the latter, “and abstain from whatever is deleterious and mischievous,” or in 21st century vernacular: Do no harm.
An interesting statistic reveals that 65 percent of the American population feels certain they are better at math than half the general population. While both ironic and funny, it is also quite telling of how people naturally tend to overestimate the likelihood of positive outcomes compared to less desirable results. It is simply human nature to hope for the best outcome. For the most part, there is no real harm in believing one’s math skills are better than they really are. But, when you overestimate the reliability of equipment that you count on every day to perform your various jobs, the results are not just surprising – they can be dangerous.
As we struggle to move from reactive to proactive maintenance, maybe at some point we just need to stop and ask ourselves the basic question:
"Do we really want to be proactive in maintenance? Really? Honestly?"
BRIEFLY RESTATING THE DIFFERENCE:
REACTIVE MAINTENANCE is dealing with loss issues due to equipment malfunction that show up unexpectedly and repairs have to be done immediately, on a crisis basis, in a very inefficient, unplanned, unscheduled way.
PROACTIVE MAINTENANCE is monitoring equipment for signs of deterioration and performing the necessary repairs and adjustments, when needed, in an efficient, planned, scheduled way, before a loss issue actually happens.
Who wouldn’t want to operate in the Proactive Mode?
When industrial companies have to take facilities off-line for essential maintenance or upgrades, careful management of the process is key. These turnarounds, or TARs, can be complex and require meticulous planning and solid execution because delays only mean more lost production and higher costs.
Judging from the independent perspectives of three very different industry observers, the Internet of Things (IoT) for asset condition monitoring (ACM) applications is quite far into the future. Plant Services, a mainstream industrial trade publication, Gartner, Inc., a prominent global market research organization, and Russell Reynolds Associates, a leading global executive search firm, have each recently published surveys and opinion pieces that offer the perspective of industry insiders on the outlook for IoT ACM applications. The consensus is that the market may not be as ready or willing as its suppliers would have everyone believe.
