Definition: Preventive Maintenance (PM)

When discussing improvement opportunities in your plant, does preventive maintenance ever come up? I’m sure it does. We are often in plants when these discussions take place. An interesting phenomenon is that most plants haven’t defined what preventive maintenance is, even though the topic has been discussed for years. Many feel it is obvious what preventive maintenance is, is it really?

Test it in your plant next time you are discussing preventive maintenance. Ask specific questions such as: “Is detailed cleaning of equipment included?” or: “is good operating practices part of PM?” and “Is balancing part of our PM’s?”

IDCON’s definition of PM is the following:
All actions performed to prevent failures or detect failures early

To define PM further we can use this visual chart:
