Maintenance involves repair and upkeep of equipment and machines. Maintenance workers need to do their jobs quickly and efficiently to lower costs, and increase safety.

Reactive maintenance (RM) was the chosen approach to maintenance, but today preventive maintenance (PM) is used more cost-effective than reactive maintenance in a lot of situations. Predictive maintenance (PdM) is a maintenance technique using scheduled maintenance not based on machine age as in PM. Many industrial companies now have reliability-centered maintenance (RCM) techniques into their programs. RCM meets the need of today’s complex machinery. Another approach to maintenance is total productive maintenance (TPM), which is a team approach to maintenance where everyone uses his or her knowledge together.
A lot of companies combine several maintenance approaches into their facilities. They realize that scheduled maintenance is necessary to reduce machine downtime and increase safety and efficiency. A maintenance department can use a computerized maintenance management system (CMMS) to schedule work.
