Maintenance Management 201: Part 3

Maintenance Management 201: Part 3

  • A good Predictive Maintenance program will allow you to sleep at night.
    The Maintenance Manager position can either be very frustrating or very rewarding. Frustrating in that breakdowns can occur at any time, and (in strict compliance with Murphy’s Law) invariably at night or on weekends when the equipment is needed most and when your family is depending on you to be with them and not at the plant. Rewarding in that there is a proven answer to those breakdowns if you have the foresight to implement a sound Predictive Maintenance program.

    The key to maximizing your free time is to know the condition of your equipment. PdM technologies enable you to identify potential defects within equipment, usually while the equipment is still in operation. Often, some of these problems may be caught early enough that the condition can be corrected before the equipment suffers damage. With the right training, feedback, and experience, PdM technicians will also be able to give you a prognosis of the equipment’s remaining life which will allow you to take care of the problem on your terms and your schedule instead of at Mr. Murphy’s whim.

    Not every potential failure is detectable, but the vast majority are with the right technologies employed – and new technologies are being developed every day. PdM is not “magic”; it’s hard science. The warning signals are real if we are perceptive enough to listen. Applying the right technology to the right equipment and potential failure mode will give you the ability to determine equipment health and increase your confidence that you can make plans with your family that won’t be interrupted.


  • Costs cannot be permanently reduced without making work go away.
    We live in a global economy. Most North American industries compete with companies in countries that have significant business advantages, such as lower taxes, lower labor costs, or government subsidies. There is tremendous pressure to cut costs to keep market share, and maintenance costs are typically a big target. In fact, it’s really easy to cut maintenance spending – just lay off maintenance crafts people and decide not to do routine maintenance. You’ll be a hero – for a little while. Sooner or later, neglect will come back to haunt you.

    The only true way to permanently reduce maintenance costs is to permanently eliminate work. There are several ways to do this. Make sure the basics of cleaning, lubrication, and contamination control are in place. Implement a precision maintenance program to make equipment last longer (point 5). Use PdM to reduce the scope of repairs by correcting incipient problems before failure (point 9). Avoid unnecessary “open and inspect” intrusive maintenance that usually causes problems due to contamination and reassembly errors. Ensure that the craftspeople have sufficient skills and procedures (point 4) to do the job right the first time. Carefully assess all work requests from the field to determine if it truly adds value and should be done – otherwise, reject it.

    Deferring maintenance spending is a short-term fix that has long-term implications. If you have not changed the “system” (see point 6) by any of the above techniques, expect the costs to rise six to twelve months in the future – and they will keep rising. Sustainable maintenance cost reduction is a result of doing the right things to make the work go away, not because of some misguided attempt to stop spending money.
