FMEA 2nd edition - under the "Development of process FMEA" it has been stated that a process FMEA should begin with a flowchart/resk assessment of the general process and in addition Appendix C says FMEA is required only for high risk operation but this statement has been removed from the third edition FMEA. Therefore are we required to look at the existing FMEA and conduct FMEA for medium and low risk operations.
I don't know for which second edition the question is about (and the posting is too old), but there is a JEDEC publication Potential Failure Mode and Effects
In the previous revision (JEP131, February 1998) flowchart/risk assessment of the process steps was recommended and FMEA was required only for high risk operations.
In the new revision this requirement was removed and I think this is right decision - risk assessment cannot be made before to make the FMEA.
What is your oppinion? One of our suppliers and one of our customers continues to make risk assessments of the process steps before FMEA form to be filled in. And only the operations with "Higher risks" are included in the FMEA...
