Maintenance strategies and practices have evolved. From reactive, preventative, predictive to proactive maintenance – all or parts of them continue to be used in some industries and plants but not all of them work. In fact, some of them, like predictive maintenance failed. CMMS systems have greatly contributed to the evolution of maintenance. It gave us better order & structure. It contains many records including items like a machine's assets condition monitoring (CM) history. However, in most cases, what’s not in it is the initial installation or commissioning report. As an industry, we often overlook the importance of the installation and commissioning report data. In many cases, it’s assumed that the installation was done correctly and that’s why predictive maintenance failed. All the CM data was incorrect because we were working off the wrong benchmark. In our experience, we know that there are still many companies who have not subscribed fully to the precision maintenance philosophy, which is: installing, maintaining and working to a recognized standard. One of the reasons for this was that there wasn’t one until the ANSI Shaft Alignment and Machinery Installation Standard came out in 2017. New technologies like motion amplification cameras are now game changers in revealing how important the machinery installation and precision maintenance as a whole is. Seeing and watching a video broken down at that frequency, showing a machine moving and vibrating excessively allows us to now pinpoint exactly what the issue is. Instead of only a select few who know specific CM technologies, this is a visual that everybody can see and understand that the machine has not been installed correctly. The introduction of the Industrial Internet of Things (IIoT) is a further step in the evolution of maintenance. In order for us to keep our machine assets running for their full life cycles, the initial precision installation, commissioning and continued precision maintenance practices must be done including the report the machines history before you can begin to collect data for CM analysis. If we don't do this, our maintenance strategy will fail like it did for predictive maintenance.
