Important Points

Breakdown maintenance	It is a type of maintenance used for equipment after equipment break down or malfunction is often most expensive
Preventive maintenance	It is regularly performed on a piece of equipment to lessen the likelihood of it failing. It is performed while the equipment is still working so that it does not break down unexpectedly. It is most effective maintenance
Predictive maintenance	It is first to predict when equipment failure might occur, and secondly, to prevent the occurrence of the failure by performing maintenance. Monitoring for future failure allows maintenance to be planned before the failure occurs.
Shutdown Maintenance	Shutdown Maintenance is maintenance that can only be performed while equipment is not in use. Shutting down machinery can be costly, but sometimes due to the nature of the defective part/machine, shutdown maintenance is the only viable maintenance procedure.
Corrective Maintenance	This type of maintenance is carried out to correct errors that were not discovered during the product development phase.
Perfective Maintenance	This type of maintenance is carried out to enhance the functionalities of the system based on the customer’s request.
Adaptive Maintenance	Adaptive maintenance is usually required for porting the software to work in a new environment such as work on a new computer platform or with a new operating system
