What is Maintenance?

People are willing to take proper care of what’s precious to them. For instance, An individual may take his car to the car engineer for servicing while another will call for the generator repair guy to service his generator.

Note: The car and generator in the above instance may not necessarily be in a completely bad shape; but the fact remains that if left unchecked, a greater damage may result.

Any action that involves the servicing, checking, replacing and repairing of an equipment, object or device is known as maintenance.

Maintenance has 2 main goals:

  1. To prevent a breakdown.
  2. To repair the breakdown.

An individual may attempt to manage cost by carrying out maintenance before a damage or breakdown occurs.

Please read more on Cost here.


Types of Maintenance

There are generally 6 main types of maintenance. Below are explanations of some of these:

  • Preventive Maintenance

Preventive maintenance is carried out routinely on a device even though no apparent fault may be present on such device.

The goal of preventive maintenance as the name suggest is to prevent a sudden breakdown on a device or equipment.

As an instance, a person who services his or her car monthly even though the car is still able to function correctly is said to be carrying out preventive maintenance on the car.

In the course of a preventive maintenance, worn out parts may be discovered and replaced as soon as possible. Also, there may be a change of oil while other little adjustments may also be carried out.

Please read on the Parts of a Refrigerator and how they operate here.

We can even carry out preventive maintenance on our body to prevent certain diseases. For this reason, some persons have discovered cancerous cells in their body through regular medical checkup; and were able to kill such cells before they become malignant.

As a matter of fact; immunization is a form of preventive maintenance.

Please read more on Immunization here.

Note: Preventive maintenance is considered to be the best form of maintenance.

Preventive maintenance may be defined as the routine check on an object or equipment before it fails or develop a fault.


  • Corrective Maintenance

Corrective maintenance is carried after the breakdown of an object or equipment had occured. It may require a change of the damaged part or another form of repair on such damaged part.

An instance of corrective maintenance is seen when a knocked engine had resulted in a car failure. The car owner will either repair the faulty engine or buy a new engine. The latter can be quite expensive.

Note: The goal of corrective maintenance is to correct the resulting damage.

We have heard news about collapsed buildings because the owners of such buildings took no account of preventive, predictive or periodic types of maintenance. The sad thing about this is “death” which may result before corrective maintenance is done. Also, imagine the amount of road accidents that would have been prevented if only we had properly working cars on our roads.

Please read on the Characteristics, Functions and Importance of Government here.

Corrective maintenance may be defined as the repairs that are carried out after the damage of an object or equipment had resulted.


  • Predictive Maintenance

Some persons may be able to predict when a damage will result based on various signs. Nowadays, the development of technology has increased the rate of predictive maintenance. To achieve this, sensors are used to monitor the workings of various part of an equipment, object or machine.

Please read on the Internet of Things to better understand how Sensors work.

The sensors send information about the impending damage to the user via a network.

Please read on Networks here.

Predictive maintenance is quite efficient in the way it works since it reduces unnecessary spending.

Please read on Scale of Preference and Opportunity Cost here.

Predictive maintenance is defined as the repair carried out on an equipment or object after a correct prediction of an impending fault.


Other types of maintenance are:

  • Periodic maintenance
  • Reinforcement
  • Overhaul
