Process Failure Modes Effects Analysis
PFMEA BenefitsPFMEA Benefits
• You can effectively PreventPrevent– rework, retest, re-inspection, poor quality, higher costs, etc.
• It costs companies less to prevent problems than to react to them (Firefighting = Dollars Wasted)(Firefighting = Dollars Wasted)
• You can improve Cycle-times– Time, Labor, and money is more effectively spent on “preventing”
rather than “reacting” to errors
• PFMEAs make teams more effective!
By PreventingPreventing errors or problems…
You prevent waste, improve quality and You prevent waste, improve quality and cycle-times, and reduce costs !cycle-times, and reduce costs !
Process Failure Modes Effects Analysis
How do we perform a PFMEA?How do we perform a PFMEA?
#1: Identify the process or product that requires the PFMEA #1: Identify the process or product that requires the PFMEA Analysis …Analysis …
Recommended:Recommended:
• New processes being launched
• Business, transaction, service, or manufacturing process
• Current processes with poor yields, rework, errors, defects, poor cycle-times, high costs, high customer dissatisfaction, etc.

Complete the next column in the PFMEA tool…Complete the next column in the PFMEA tool…• Column 3 – Brainstorm and list all the “effects” of the
failure mode(s )if it actually occurred. The “effects” of a failure, defect or error could be both the internal (e.g. at the next operation) effect and the external effect (e.g. at the customer)
In Column 3 – List all of the potential (internal and external) effects of the
Failure Modes, defects or errors : Example- Customer rejects, poor fit,
rework, cycle-time increase, test failure
This “effects” list will help you determine the “Severity” ranking to be
placed in column 4
