The cost of maintaining equipment can be much higher than we realize. Sustaining equipment for its original design consumes time, labor, materials, tools, facilities, and most importantly lost production. Higher costs occur when a greater loss of production is incurred and it takes more time, resources and materials to correct the problem than it did to prevent it. Reducing equipment downtime and related cost is the greatest argument for planned maintenance versus unplanned maintenance.
Most people know planning ahead is the best approach to preventing corrective maintenance. Preventive maintenance reduces reactive or breakdown maintenance, resulting in lower cost. In essence, you actually will repair things less often if you do a good job at being proactive and heading off those expensive disasters. You pay penalties when you respond to problems rather than preventing those problems. Are you with me?
Many organizations consciously decide to Run To Failure (RTF).
