5. FMEA (failure mode It aimed at preparing Very beneficial in case of new

identifying all possible failures the goal is a quality improvement,

process. It has two types: process deeply.

Development failure mode

production failure mode

effect analysis (PFMEA).

This method requires extensive

knowledge of design and

process.
