9. FMEA Key Management Aspects
Part/Process Integration
•FMEA is about part and process. Changes on these items can impact the FMEA.
Centralized hosting
•All the FMEA in one organization should have the same format and be hosted in the same place to
facilitate analytics and reports
Standardized entries
•To get a real value out of your FMEA reports you need to be able to have standardized entries. Two
similar causes have to have the exact same name.
Fill Collaboratively
•Creating an FMEA is a lot of work and people specialist on each area should write their section of the
FMEA.
Send Actions
•An FMEA’s target is to lower risk by running preventive or corrective actions based on a risk analysis.
Actions are run by multiple peoples, you can’t just send emails.
Consume actions’ outputs
•Once the action are run. The output should be a change of the risk values. These should be easily
updated in the FMEA.
