Using Fmeca to Derive Criticality-Based Maintenance Programs

Abstract

Failure Modes, Effects and Criticality Analysis (commonly known as ‘FMECA’ and often confused with the term ‘FMEA’), is a well-established tool in the management of technical risk, during the design phase of most modern projects and products.The technique originates in the 1950s from work carried out by the US Navy, developed by NASA during the 1960s and furthered in the 1970s by the automotive industry, the technique now has wide-spread use and is universally accepted as the “right approach” to technical risk management.It is much less commonly understood, that the technique can be used to manage risk in all phases of the product life-cycle; from design through prototype test, beta-field release, manufacture and operation/deployment, including field-maintenance. This article summarises the use of this technique in establishing a simple RCM (reliability-centred-maintenance) programme, with a view to;• Supplying criticality-based field-service recommendations to the client• Satisfying key elements of the PAS55 Asset Performance Management framework• Discussing the organisational challenges and lessons-learned from the undertaking.
