Increasingly, contracts are requiring FMEA’s to be performed as a condition of placing the order. Also, the use of FMEA minimises the company’s likely exposure to very expensive product liability claims.
Failure Mode and Effects Analysis (FMEA) is a logical technique used to identify and eliminate possible causes of failure.
The technique requires a sequential, disciplined approach by engineers to assess systems, products or processes in order to establish the modes of failure and the effects of failure on the system, product or process. This is to ensure that all possible failure modes have been fully identified and ranked in order of their importance.
The FMEA discipline requires the engineers to document their evaluation with regard to the failure mode, effect and criticality. The analysis work can be applied at any stage; design, manufacture, test, installation or use, but is best performed at the design stage. In a simple system the study may be performed on the total system or product but with more complex systems it may be necessary to break the product down into various sub-systems or sub-assemblies.
