Failure Mode and Effects Analysis (FMEA) is one of the first systematic techniques for failure analysis. It involves reviewing as many components, assemblies, and subsystems as possible to identify failure modes, and their causes and effects. For each component, the failure modes and their resulting effects on the rest of the system are recorded in a specific FMEA worksheet.
A typical FMEA worksheet should include the following :
– Probability of Occurrence (OCC) : How often does this occur ?
– Severity (SEV) : How severe is the effect to the customer ?
– Detection (DET) : How well can you detect the cause or failure mode ?
– Risk Priority Number (RPN) : This is the risk priority (OCC x SEV x DET). A higher number indicates a higher priority to allocate resources to get it resolved.
– Implementation Plan : Recommended action plan with specific process owner
FMEA also encourages strong team participation amongst different departments, resulting in the rapid and complete delivery of information required to prevent failures.
