Failure mode and effects summary FMES

There are a number of sources of data for failure rates, including Failure Modes and Effects Analysis (FMEA)/Failure Modes and Effects Summary (FMES), product data sheets, failure tests data and accelerated life tests. However, these sources ultimately stem from the following data types ... 

Failure Modes and Effects Summary (FMES) Number Revision Date ... 

The total failure rate for each failure effect category may be detailed in a summary sheet or is summarised in the Failure Modes and Effects Summary (FMES, see Section 5.2.5). 

The results of an FMEA may be used to generate the Failure Modes and Effects Summary (FMES). This is especially useful for very large FMEAs or to consolidate individual piece-part FMEAs. 

Component designers (i.e. System Level 2 in Fig. 1.1) may be required by the system integrator to develop a piece-part FTA with a top-level event for particular failure modes of a unit. The piece-part FTA would then develop through layers of logic gates until individual component failures (resistors, capacitors, etc.) are identified. This is often supported by a Failure Modes and Effects Analysis (FMEA) from which a Eailure Modes and Effects Summary (FMES) (see Chapter 5) can be generated for the individual next or end effects.
