Best Practice : Reliability-Centered Maintenance: New Equipment Process (Classic RCM)
CACI’s method of applying Reliability-Centered Maintenance improves equipment readiness while minimizing total ownership cost for owners of capital assets. CACIs unique process is repeatable and applicable anywhere, ensuring the right mix of preventive maintenance while delivering improved equipment readiness.
CACI International’s Classic Reliability-Centered Maintenance (RCM) process optimizes preventive maintenance when little to no operational experience exists for an equipment or system, ensuring the right mix of preventive maintenance while delivering improved equipment readiness and minimizing total ownership cost for owners of capital assets.
CACI’s Classic RCM is a unique, top-down approach to identify initial maintenance requirements when little or no operational experience exists for an equipment or system. Developers using this methodology are guided by CACI’s expert in-house staff in developing system maintenance requirements. RCM practitioners trained in this process begin with four basic maintenance questions:
What function does the hardware perform? Perform or performance in this instance denotes a range, for example from 10 to 20 hertz (Hz) versus a specific setting of 15 Hz. In other words, what are the parameters or is there a range in which this hardware/system operates?
What failures interrupt those functions? Students examine how the hardware fails, and then examine the details of the hardware failure and its impact on the mission – not the mission of the hardware or system but the overall mission of the platform or environment in which it operates.
What, if any, are the additional associated risks and consequences of those failures?
What maintenance can be done to prevent failures? Should an action be taken as a result of this failure? Should I do something? Do I care if this hardware/system fails? The end result is a methodology to develop cost-effective maintenance that preserves the intended functions of equipment and systems.
The origins of CACI’s Classic RCM date back to commercial aviation industry in the mid-1960s. Since then it has been widely accepted by the military and industry as the definitive way to identify the appropriate maintenance. CACI’s unique hands-on approach to classic RCM virtually ensures hardware/system maintenance optimization reliability and maintainability, enabling increased operational availability. Classic RCM optimizes preventive maintenance when little to no operational experience exists for an equipment or system, ensuring the right mix of preventive and corrective maintenance.
CACI’s classic RCM methodology develops validated maintenance requirements. Certified practitioners ensure a standard repeatable approach is used to develop the optimal level of maintenance. CACI provides process-based classic RCM training that is the key to success of the classic RCM process. Students attending CACI’s RCM course are guided through multiple practical application examples to illustrate the RCM processes that prepare them for the certification examination. The course is five days in duration and taught by an approved NAVSEA 04RM instructor. Level II certification is valid for three years and can be renewed by attending another Level II training class or by satisfactorily completing an online recertification examination.
RCM provides the rules of evidence (Figure 2-4) that is the core, and Condition-Based Maintenance (CBM) is a maintenance strategy based on the “evidence of need” for maintenance. Figure 2-5 illustrates the class RCM Logic Tree. RCM is a logical, repeatable analysis process to determine validated task needs and make improvements.
