Which is NOT a function of the Planned Maintenance System (PMS)?

The Planned Maintenance System (PMS) primarily focuses on the maintenance of equipment to ensure its reliability and efficiency through systematic planning and scheduling of preventive maintenance activities. The goal of PMS is to minimize downtime and maximize operational efficiency.

The correct answer identifies that conducting equipment upgrades is not a function of the PMS. Upgrades generally involve major modifications or replacements to equipment to improve performance or technology. While upgrades may be necessary over time, they fall outside the regular maintenance activities that PMS is designed to handle.

In contrast, planning preventive maintenance, scheduling maintenance tasks, and accomplishing maintenance efficiently are all integral functions of PMS. Each of these functions works to help organizations maintain their assets effectively, ensuring that equipment remains operational and reliable without the interruptions that upgrades might require.
