Because FMECA usually involves very large data sets, a unique identifier must be assigned to each item (function or piece part), and to each failure mode of each item . </P> <P> Failure effects are determined and entered for each row of the FMECA matrix, considering the criteria identified in the ground rules . Effects are separately described for the local, next higher, and end (system) levels . System level effects may include: </P>

The fmea process accommodates the interaction of two failure modes
