Applying PDCA to Plant Maintenance: An Overview

The PDCA (Plan-Do-Check-Act) method can be extremely useful in a variety of environments, and its flexibility is one of the main drawing factors for many leaders. When applied correctly, it can accelerate improvement in an organization by a noticeable degree, and can help the company push all of their processes and products towards their limits without exceeding them in a potentially harmful way.

Plant maintenance is a field that can especially benefit from a proper application of PDCA, and learning the ins and outs of the methodology can have huge benefits in this area. As long as every step is carried out correctly, and there is a good system in place for verifying results, you can often see improvements realized in very fast iterations.

Adapting PDCA to Plant Maintenance

When you want to improve your plant maintenance operations through the PDCA cycle, you just have to think about how you can adapt each separate step on its own, and lay the altered version of the cycle over the original implementation.

Each of the four steps will usually have to be changed to some extent in order to make it work better in your specific context, but the good news is that it’s often not that hard to make those changes if you already have some experience applying PDCA from before.

On that note, remember that you may sometimes not actually need to change some of the steps in order to see good results. Don’t automatically start implementing changes for the sake of it, and remember to validate the impact of everything you’re doing before and after making those changes. Otherwise, you risk running into even greater problems down the road.

Improving Inventory Practices

One of the areas that can usually see the biggest improvements when it comes to plant maintenance is the way inventory is stored and organized. It’s not rare for a facility to see significant improvements in its capability to handle complex orders by simply improving the way the inventory is being handled, and you’d be surprised how much room for improvement there usually is in most places.

The good thing about the PDCA cycle is that it gives you actual, verifiable results instead of having you shoot in the dark, and it allows you to easily modify each aspect of your operations until you’re happy with the final result. That way, you can focus on making actual improvements instead of having to spend too much time analyzing the situation and assessing the risk from each change.

Inventory improvements usually lend themselves to PDCA in return too, as there is a lot of opportunity to collect and analyze data in this area. Once you take a look at the big picture from above, you’ll usually start noticing some patterns, and sooner or later you should have a more adequate idea of where waste can potentially be minimized in your operations.

Don’t Rely on PDCA as a Universal Solution

There is one caveat to this all, and that’s the importance of realizing that PDCA is not a magical solution that can automatically resolve all problems in your plant’s maintenance. You should treat it like another tool in your arsenal, and combine it with other proven solutions to get your desired results. Sometimes there will be a more appropriate solution to a given problem, and you should focus on what works instead of what you’re most comfortable with.

Conclusion

PDCA can have great uses in the area of plant maintenance, but it’s important to apply it carefully and in a controlled manner, keeping some of its shortcomings in mind. It’s also a good idea to learn how to combine it with other tools in the area of improvement and problem solving, so that you’ll always have the confidence that you’re using the full range of possible solutions available at your disposal.
