Did you know that equipment PMs (Preventive Maintenance) tend to become more expensive over time? Why does this happen? For example, additional maintenance steps tend to be added to a PM as time passes. The machine configuration (design installation) changes and the PMs are never updated to reflect these modifications. Some PMs are not written correctly in the first place. All of this means that unnecessary maintenance is performed on your machines costing a lot of resources and money for a very long time. These are just some of the reasons PMs can be costly.
RCM and FMEA functions usually cost more money upfront and tend to be avoided as a result. However, these functions can clearly identify what maintenance actions should be performed on equipment and guide you to steps that will avoid maintenance issues. Condition Monitoring is another tool that works directly with RCM and FMEA functions to reduce PM activities and drive better equipment performance and reliability. These activities may cost more upfront versus a PM but will be much more cost-effective in the long run.
