Once the FMEDA has been configured we need to then systematically detail the failures for each component and their failure modes to determine if the particular failure is safe or dangerous in our system.

This process is considered PRIOR to any diagnostic functions.

For each component and its failure mode:

• Determine the local effect of the failure
• Determine the system effect of the failure
• Determine if the failure is safe or dangerous prior to diagnostics
• Apply any justifications

As the process is a systematic process each failure mode must be determined prior to proceeding.
