3.2 When to Perform an FMEA 3.2.1 Equipment Life Cycle The recommended method for performing an FMEA is dictated by the equipment life cycle. The early stages of the equipment life cycle represent the region where the greatest impact on equipment reliability can be made. As the design matures, it becomes more difficult to alter.

6. Appendix 3 – Failure Mode Effect Analysis (FMEA) The principle of FMEA is to consider each mode of failure of each component in turn and determine the effects. The FMEA can be undertaken from the perspective of system operation, product quality or EHS but not all three at once. For example, a component whose failure will cause significant

Machinery FMEA is a methodical approach used for identifying risks associated with machinery and equipment failure. The purpose of the MFMEA is to increase reliability of the machinery, reduce time to repair and add prevention techniques, such as diagnostics. MFMEA is an integral part of Total Predictive Maintenance (TPM).

FMEA proves to be one of the most important early preventive actions in system, design, process, or service which will prevent failure and errors from occurring and reaching customer. FMEA's are conducted in the product design or process development stages, although conducting an FMEA on existing products or processes may also yield benefits.
