What term describes the mandatory checks and tasks to maintain equipment functionality within the 3-M system?

The term that describes the mandatory checks and tasks to maintain equipment functionality within the 3-M system is "Planned Maintenance." This type of maintenance involves scheduling and performing specific actions to ensure that equipment remains operational and safe, which is critical in maintaining functionality and reducing the likelihood of unexpected failures.

In the context of the 3-M system, which stands for Maintenance, Material Management, and Management Information Systems, planned maintenance is part of a structured approach that encompasses both routine and preventive activities intended to uphold equipment performance over its lifespan. It encompasses various tasks that are scheduled in advance based on the manufacturer’s recommendations or historical performance data.

While routine maintenance, corrective maintenance, and preventive maintenance are important concepts, they do not fully capture the comprehensive approach encapsulated by planned maintenance, which is proactively organized and sometimes includes both preventive and predictive strategies to ensure seamless operation.
