PII has developed a comprehensive method of analyzing designs capable of determining the real-world reliability of the component or integrated production line and prioritize the CM and PM programs for maximum effectiveness. This method is called Critical Components Management (CCM).
This method identifies those pieces of equipment and associated components which are critical to availability, then determines the real-world reliability to establish an objective expectation of future productivity. If possible, and based on the business' needs, contingency plans are developed, such as design improvements, on-line monitoring/repair, recovery procedures, etc., before the equipment is turned on.
This approach has helped many operations focus on the real-world issues of productivity, rather than on subjective expectations that management may have formed based upon vendor information. For example, DNMC, a flagship, high-reliability 4-unit plant, and TVA Sequoyah, a 2-unit high-performing site, have used this method to significantly reduce unexpected outages.
