Improve your preventive maintenance

Improve your preventive maintenance

Almost every maintenance organization strives to decrease the amount of corrective maintenance and unplanned downtime. To get away from it, we use preventive maintenance and that is a good thing. But we need to make sure we are not overdoing preventive maintenance.

We use maintenance to maintain or reset the capacity in our equipment’s, but the need of maintenance can change over time. The age of the equipment, products produced in it and how exposed it is to external impact such as weather, are things that has an impact on the equipment.

    • To ensure that our preventive maintenance is effective, even when there is a change in need, we recommend using completion codes. In MaintMaster’s standard setup we use 3 completion codes to follow the development of our preventive maintenance. Those can be found in completion code group PM Performed according to routine:
    • Status OK
    • – The equipment is in good condition and approved for continued use.
    • Deviation identified
    • – Equipment or component does not correspond to the standard or does not maintain satisfactory performance. Follow up with actions by creating a follow-up job.
    • Deviation found and corrected
    • – A smaller deviation was identified and corrected. No need for a follow up but performed actions should still be reported in the job.
    • Status OK (change procedure)
    • – The equipment is in good condition and approved for continued use, but the procedure or intervals need to be adjusted in the original job/template.

Please note, the completion code “Deviation found and corrected” is rather new so if you are missing it in your system, contact us and we will help you!

I would also like to add 2 things.
1. If you have a lot completed work orders with the code “Deviation identified” you should perform a root cause analysis on each follow up to find and fix the real cause, to increase the equipment’s capacity.
2. For work orders completed with “Status OK (change procedure)” it is an advantage if the one reporting, can describe what you need to change – interval, material, technique or other. It makes it easier to discuss necessary actions.

 

Once you compile historically produced items in an equipment and put it with completion codes, you can see the change in demand of maintenance depending on product. Or, if the equipment is exposed to external impact such as weather, you can easily find out when you need a more intense preventive maintenance, and when not.

 

Whenever you want to talk about how and why you should improve your preventive maintenance, get in touch with me or any of my colleagues.

Talk to you soon!
