– a Key Step in FMEA Preparation

“. . . not everything that can be counted counts” Albert Einstein

A key, but often missed, step in FMEA preparation is to identify and prioritize the functions that relate to the item being analyzed. These become candidate functions to be brought into the FMEA.

When creating a robust design, there is probably no more important consideration than identifying the correct parameters and associated values. A robust design is insensitive to anticipated variation and P-Diagram visually shows the relationship between what the system is designed to do, the anticipated noises the system will encounter and the correct parameters to achieve the desired outcome. P-Diagram  can be an essential input to FMEA.

Once you have identified the scope of the FMEA project, made the scope visible, it is time identify the FMEA team members. This article discusses the composition of the FMEA team, including why each member is needed, and the underlying reason for a cross-functional team.

FMEA teams should agree to the ground rules that guide the analysis and the underlying assumptions that impact the entire FMEA. Failure to do so will add complexity and confusion to the resulting FMEA, and waste people’s time. Don’t miss this important step in FMEA preparation.
