Maintenance and repair are two very important terms in the asset management space.
Whether we’re talking about the maintenance and repair of commercial aircraft, fleets on the road, large manufacturing equipment or that small suburban property we rent, it’s how each physical asset works optimally and can achieve his goal.
In essence, maintenance has the same ultimate goal: to get the most useful life out of the tools, equipment and infrastructure in use.
However, the path they take to achieve this goal is very different.
Repair is an action we take to restore an asset to working condition.
The level of repair we need to do depends on the level of damage that caused the asset to malfunction.
We can divide equipment failure into two different types:
✔ Minor breakdown
The asset can generally continue to be used, but does not provide full functionality (like a car with a flat tire) and may be unsafe. Oftentimes, the maintenance team can take quick corrective action to restore the equipment to full operation before the problem becomes a complete failure.
✔ Complete failure
It is not possible to use the asset until it is fixed. The amount of money spent on the repair depends on the main reason for the failure. If we go back to the car example, there is a big difference between changing a tire and changing a car engine. Both cause total failure, but the time and cost to repair is very different.
Equipment failure can be very expensive. Some of them are the result of human errors, unauthorized accidents, and natural wear and tear that occurs over long years of use. It is impossible to control these factors. As mentioned, most breakdowns and subsequent major repairs are preventable, thus leading us to preventive maintenance.
Maintenance is often used like an umbrella for all equipment.
The easiest way to distinguish between maintenance and repairs is that “repair” is the set of actions that occur after an asset has failed or failed, while “maintenance” is the action taken to keep the asset healthy and Unexpected failures are prevented.
