5 Pillars of Maintenance and Reliability

Maintenance and reliability are closely related disciplines that determine how effectively an organization can keep its assets performing at peak levels.

The maintenance management focuses on the maintenance inspection, reactive, repair, and on-demand service requests. However, reliability management emphasizes preventing equipment failures and ensuring consistent asset availability over time.

The maintenance and reliability create a proactive approach that reduces downtime, lowers costs, and maximizes the lifecycle value of critical assets.

According to the CMRP (Certified Maintenance & Reliability Professional) framework and Society for Maintenance & Reliability Professionals (SMRP), there are 5 Pillars of Maintenance and Reliability:
