6. FMEA(C) limits
6.1 FMEA's reputation for completeness
FMEA(C) has the reputation of being an exhaustive method. Its systematic (even tedious) nature justifies it, provided the conditions for success are met and within the limits of the method:
insofar as the decomposition of the system omits no element, and all possible failure modes of each element are known and exploited, the systematic nature of the method effectively guarantees that all failure modes are taken into account;
but the method does not produce an exhaustive list of common modes, nor does it systematically evaluate failure combinations

FMEA(C) limits
Conclusion
Appendix 1: FMEA for a lamp post
To illustrate our approach, here's a virtual example of a FMEA analysis. In order to present a fairly small FMECA, the system studied is a simple object and the decomposition is not detailed. This analysis has no claim to relevance, and is intended only to illustrate the approach.
The object under consideration is an ordinary floor lamp.
