Regular preventive maintenance (PM) makes up a large portion of many maintenance programs and, sometimes, we don’t get the results we want out of all that maintenance. Reliability professionals should evaluate their PMs to ensure effectiveness both from a reliability & cost perspective.
Here are 3 questions to ask yourself during your next PMO
- Does this task address a specific failure mode? Sometimes a PM can include too many tasks (inspections, replacements, etc.). Each task should address a specific failure mode to ensure that it’s useful to perform during the PM.
- Is the time interval appropriate? From RCM, we learn that there is an optimal interval to perform maintenance for each failure mode. If we look at each of the tasks and what interval they are required, we can optimize the entire PM.
- Do we have data to back up our decision? If we think that we’re doing a PM too often, can we trial an extended interval to ensure it works? What about vice versa? What data do we have? Data will always be useful in backing up our optimization decisions.
If done well, PMOs are great at improving your maintenance program both from a reliability and cost perspective. Have you done one recently? If so, what were your results? Hit reply and let me know!
