Raise your hand if you'd like to go from reactive to proactive maintenance.
Going from reactive to proactive is like yearning for the shiny red bike in the toy store window before Christmas. All the kids going by want one, but only a few of those kids' parents will spring for one.
Proactive maintenance is similar. All the smart maintenance professionals want it, but few companies' management will actually step up to the plate and pay. After all, the usual way to proactive maintenance is an arduous multi-year journey needing money (sometimes a good deal) and top management support.
There's got to be a better way.
Some maintain that all it takes is a good, solid preventive and predictive maintenance system (PM/PdM). However, there is a logical problem with merely installing a system unless you get extra and specific resources for the duration of the effort.
PM will get you to proactive maintenance. But without extra resources to support it, especially in the beginning, you'll need a very thick skin, a great deal of patience and a decades-long attention span.
Why? Let's consider what it means to run a reactive maintenance effort? If we look at the condition of equipment in a typical reactive organization, we would find that most have suffered deterioration. In fact, most equipment is in various states of impending catastrophic failure.
There's also no effective effort to identify deterioration that will lead to failure, nor prioritize and deal with it before the machine breaks down.
If that is the state of a reactive shop, why not use a PM system to turn the ship around? What was the logical problem mentioned earlier?
Let's assume reasonably level resources for maintenance. Your people are already working on breakdowns most of the time. Who is available to do the additional PM work load? Well usually, the PM is done during down times when there is nothing else to do. This is called "bootstrapping" the PM system.
Bootstrapping might have worked in the days when your personnel weren't already stretched so thin. Actually, it never worked that well because of the logic of PM.
Half the effectiveness of PM comes from basic maintenance tasks such as cleaning, lubricating and tightening bolts. These lengthen the life of equipment already in good shape (no critical deterioration to cause breakdown).
The other key to PM's effectiveness in reducing breakdowns is that when deterioration is found by inspectors, it is fixed before it turns into a breakdown (called corrective maintenance).
Visualize that your shop is stretched thin from cutbacks when you decide to add PM activity. On top of that, add additional corrective activity. What do you think will happen? Will you have the discipline to do corrective maintenance work on the equipment that might fail instead of working on equipment that has already failed? Remember there are no extra resources.
This is the contradiction of trying to install PM systems without adding more resources. Since PM has demonstrated it takes a year or more to start to take effect (when done fully and correctly), many more installations are abandoned during their first year than succeed. This is the reason why most PM attempts to move from reactive to proactive maintenance fail (usually not with a bang but with a whimper).
What else can be done? Another strategy is to spend some time (say a year) doing two activities at once. The first activity is getting better at reactive maintenance. Have the crew figure out what should be done to reduce the time it takes to react and repair a breakdown. Use people in teams and create a structured technique to capture ideas and propose experiments. More on the specific technique later.
Also consider Root Cause Analysis (RCA) to reduce the time it takes to be reactive. This second activity is to look at all your repetitive failures, plus any repetitive requests for maintenance help. Using established RCA techniques, try to fix them forever.
