Predictive or Preventive, That is the Question

March 6, 2012
(Predictive Maintenance and Condition Monitoring Management)

There was a time when Preventive Maintenance (PM) was the answer to increasing reliability of systems and equipment. However, PM is usually intrusive and sometimes even harmful to equipment because it may actually introduce a failure mechanism.

Predictive Maintenance (PdM) on the other hand is typically non-intrusive, is easier to schedule because shutdown is not required and actually should be the basis for most of your existing PM work.

Which is better for you personally, surgery to see if you are healthy or some x-rays, blood work or even an MRI to determine what is really going on?

Why is equipment any different? The technology is out there, lets start using it.

  • You mention in your article that predictive maintenance is "is easier to schedule ". What we have found in reality is that scheduling this activity is quite difficult. The timeframe for taking a predictive reading may be as short as 15 minutes. Therefore you must ensure you have the right people and tools on hand for this 15 minute window, otherwise consistency in readings may be lost. For predictive maintenance to be truly successful you must have a locked down robust schedule of when readings can be taken and a good communication path if schedule changes occur.
