Conducting effective maintenance on equipment is essential, whether your company is big or small and regardless the industry we are talking about. But do you know which are the right maintenance strategies for you and when should you adopt each one of them?
In this article we outline the advantages and disadvantages of Corrective maintenance to help you get a better understanding of what’s available to your business and if/when it might fit your needs better.
As we know, it is crucial to prevent technical issues with Preventive Maintenance (check our previous post), but once unexpected failures happen we have to do our best to solve them. Corrective maintenance is the technical activity carried out after a failure occurred and it is supposed to restore an asset to a condition in which it can perform its intended function, either by repairing or replacing it.
What are the advantages?
- Lower short-term costs: As a reactive activity, there is very little to actually do after the purchase and before a problem occurs;
- Minimal planning required: Corrective maintenance consists in correcting a failure identified in a particular component of an equipment or installation reported at the moment, so there’s no need for a complex and timely planning;
- Simpler process: The process is easy to understand, since you only need to take action when some kind of problem occurs;
- Best solution in some cases: When it is believed that the stop and repair costs in case of failure will be less than the investment required for preventive maintenance, Corrective maintenance is the best solution.
What are the disadvantages?
- Unpredictability: The equipment is not monitored after purchase, so the failures are highly unpredictable;
- Paused operations: Unexpected failures may result in unavailable materials and therefore delay the time taken for a repair, increasing equipment downtime;
- Equipment not maximized: This approach doesn’t protect or look after equipment and therefore reduces the lifetime of the assets;
- Higher long-term costs: Corrective maintenance is applied when it is believed that the stop and repair costs in case of failure will be less than the investment required for planned maintenance. But this doesn’t always happen. When a catastrophic failure occurs, it can be extremely costly, causing negative effects on reputation, client satisfaction, safety and on the ability to run a business efficiently and productively.
Most professionals do not really analyze the advantages of Corrective maintenance, but it is important to understand that for some auxiliary equipment this becomes more appropriate. For example, when there are assets of low criticality and the costs involved in an eventual repair are considered lower than regular inspections or preventive techniques, it is appropriate to carry out the Corrective maintenance strategy. This approach is also common when equipment failure doesn’t directly affect operations or productivity.
Even in these cases, it is possible to optimize the operational processes, reporting and solving every failure in a timely and effective way to maximize customer satisfaction. Some examples are automated technician assignments, fast reports by every member of the staff and easily organization of failures (knowing which are opened or completed). These tools that can help you handle Corrective maintenance and you can find them in Infraspeak.
The main problem comes up when Corrective maintenance it is not adopted as part of the maintenance plan, but only because there are no preventive activities. Our experience and feedback from our clients has shown us that both are essential, depending on the context and the integration on the strategic maintenance plan.
