PFMEA – Process Failure Mode And Effects Analysis

PFMEA Process failure mode and effect analysis are used to analyze and keep in check the control objectives of a process.

A PFMEA is performed on a process and not on a product; for the latter, you do DFMEA. 

The central component of a PFMEA is the PFMEA Worksheet, which can look very similar to a DFMEA Worksheet. 

In the first columns of a PFMEA Worksheet, you will break down the steps of your process instead of the components of your product as you would in a DFMEA.

You then follow the same steps you would in a DFMEA procedure:

PFMEA BREAKDOWN

  • Identify all potential failure modes of the process steps
  • Determine the effects
  • Perform a risk assessment
  • Define a plan for recommended actions for risk mitigation.
