What are the Benefits and Challenges of Preventive Maintenance?
Are you performing preventive maintenance on a regular basis? If you’re not, you may want to consider adding it to your schedule. Why? In a word, it’s about efficiency. In a few words (as its name suggests), it prevents problems before they start. Preventive maintenance is becoming the manufacturing industry standard. Roughly 80% of asset and facilities stakeholders are embracing the process as a way to cut costs, increase efficiency, and keep assets running like clockwork.
By performing regular preventive maintenance (or its cousin, data-based predictive maintenance) you are heading off problems, snafus and breakdowns at the pass. It’s about identifying and handling any potential issues that may be lurking down the road. The point is to find potential problems before they become real problems that could lead to delays and costly headaches.
The irony of preventive maintenance is that it can sometimes seem like it causes more problems than it solves. It requires regular downtime, which in itself is a problem. There’s also the tricky matter of timing. Finding the optimal time to perform the maintenance can be a delicate balance between shutting down for maintenance too soon and waiting too long.
But, the challenges are worth the rewards. Ensuring you have the proverbial well-oiled machine will make your operation more efficient and productive now and in the future.
Let’s take a look at preventive maintenance benefits and challenges and how it can help boost your operations.
Preventive maintenance benefits
The idea behind doing regular maintenance on the lifeblood of your manufacturing operations — your machinery — is to keep it humming along at optimal efficiency and prevent any problems that might occur. Benefits to making it a regular part of your business process include:
You control the downtime schedule. It’s true that performing maintenance requires downtime. You’ll experience a work stoppage because of it. However, the good news is, when that downtime happens is up to you. You can schedule it for slow periods and avoid your high-volume times. Build maintenance into your schedule as a regular part of your routine.
Fewer surprises. A snafu happens, something breaks, and you have to stop production to figure out what it is and fix it. That can happen at any time, and trust us, it will happen when you least want it to. Performing preventive, not reactive, maintenance will lessen those unwelcomed surprises that erode your productivity and profitability. A general rule is that planned work will cost two-thirds less than unplanned work in time and other resources.
Increased efficiency. At USC Consulting Group, we’re all about efficiency, and one of the surest ways to find “hidden efficiencies” that you didn’t even know were possible is to perform regular preventive maintenance on your machines.
Increased longevity of your machinery and assets. This is key. Just like your car needs regular oil changes and tune-ups to keep it running at its best, so do your assets.
Preventive maintenance challenges
There are some challenges with doing regular preventive maintenance. However, in our view, these don’t outweigh the benefits.
Finding the optimal time to do it is tricky. A regular schedule is the key to finding the best time to shut down for maintenance. And the downtime is typically where we see the most pushback from executives and managers who aren’t thrilled with this process.
It will cause shutdowns. There’s no way around it. To perform maintenance on your equipment, the line must stop.
If it ain’t broke, don’t fix it. This is an old adage for a reason. You may be shutting down for your scheduled maintenance when no problems actually exist. The shutdown does come at a productivity cost, so… is it worth it? Some manufacturers solve this issue by performing predictive maintenance instead. It’s a more complex process that is data driven, and analyzes how your assets are performing in real time. All’s well? No shutdown. But if you find problems, that’s when you act. It reduces downtime, and you’re not replacing any parts while they’re still good to go. The downside of this approach is complexity and connectivity. If you don’t have state-of-the-art machinery, you won’t get the data analytics that this process requires. That’s why the majority of manufacturers today are using the preventive approach.
