In order to balance the risk of failure and cost of maintenance, PM programs should be periodically reviewed based on failure history and performance analysis. This is called Preventive Maintenance Optimization. Preventive Maintenance Optimization (PMO) is a method of continuous improvement, working to increase the effectiveness and efficiency of maintenance activities

Preventive Maintenance Optimization Involves:

• To check maintenance tasks related to a known, consistent, wear or age-related failure mode?
• Removing all maintenance tasks that serve no purpose or are not cost effective.
• Eliminating any duplication of effort where different groups are performing the same Preventive Maintenance (PM) to the same equipment.
• Moving to a mostly condition based maintenance philosophy.
• Could certain PMs be consolidated? That is, could we do several PMs on one machine/process at the same time, vs revisiting the machine/process frequently for single PMs?
• Could certain PMs be done by operators to avoid or detect onset of failure?
