Thanks both of you, but I heard "delta-FMEA" is from Europ company, use for process difference risk analysis, looks mostly like process
FMEA application, not Design FMEA. In actually, the traditional FMEA 3 catelogies: System FMEA,
DFMEA and
PFMEA somehow not covered all the applications now, such as many people use as 'Change-FMEA' to assess the "Change" risky, and tool FMEA (or machine FMEA) etc..
