Corrective maintenance is performed after a system failure to restore operability. The process includes diagnosing the fault, replacing damaged components, and testing the system. It may be the only option for unpredictable failures or older systems where preventive maintenance is not practical.
Corrective maintenance is a form of system maintenance that is performed after a failure or problem emerges in a system, with the goal of restoring system operability. In some cases, it may be impossible to predict or prevent a failure, making this type of maintenance the only option. In other cases, a system may require repairs due to insufficient preventive maintenance, and in some situations people may choose to focus on corrective rather than preventive repairs as part of a maintenance strategy.
The corrective maintenance process begins with the fault and a diagnosis of the fault to determine why it appeared. The diagnostic process can include a physical inspection of a system, use of a diagnostic computer to evaluate the system, user interviews, and a number of other steps. It is important to determine what caused the problem to take appropriate action and be aware that multiple component or software failures may have occurred at the same time.
The next step is the replacement of damaged components or software. In some cases, the damage may be repairable, either on-site or by removing the affected item and carrying out the repairs off-site. In other cases, complete replacement with a new item may be required to restore system functionality. For example, if an optical drive in a computer fails, a technician may determine that replacing part of the drive or repairing part of it might suffice, or he may find that the entire drive needs to be scrapped safely. that a new one can be inserted.
After performing the maintenance, a technician verifies that the fix worked by testing the system. This can be done in stages to confirm that the system is running slowly before overloading it with activity. Verification is especially important on systems sent to a repair facility, as technicians want to be sure that when they are sent back, users will be satisfied with the standard of work performed.
For some older systems, it may make more sense to rely on corrective maintenance. Preventive maintenance can be expensive and, with these systems, may not be practical; it may be more cost-effective to simply repair system components when they fail. Conversely, with a newer system, preventive maintenance can save money in the long run and extend the life of the system by preventing system failures before they happen as much as possible.
