Maintenance Management
What is PM and CM in maintenance?
In maintenance management, PM and CM refer to different approaches for managing assets and equipment:
Preventive Maintenance (PM)
PM involves proactively scheduling regular maintenance activities to prevent equipment failure and minimize the likelihood of unplanned downtime. These activities are typically based on time-based intervals or predefined usage metrics. PM aims to identify and address potential issues before they escalate into costly problems, thereby increasing equipment reliability and longevity.
Corrective Maintenance (CM)
CM, on the other hand, focuses on addressing equipment failures and malfunctions reactively. When a breakdown occurs, maintenance personnel respond to the issue and restore the equipment to working condition as quickly as possible.
CM may involve troubleshooting, repair, or replacement of faulty components. While CM is essential for addressing unexpected failures, it is generally more costly and disruptive than preventive maintenance.

Both PM and CM are integral components of a comprehensive maintenance strategy, with PM aimed at minimizing downtime and extending asset lifespan, while CM focuses on resolving issues swiftly to minimize disruptions to operations.
