Transcript PFMEA Benefits

PFMEA Benefits
By Preventing errors or problems…
You prevent waste, improve quality and
cycle-times, and reduce costs !
• You can effectively Prevent
– rework, retest, re-inspection, poor quality, higher costs, etc.
• It costs companies less to prevent problems than to react to
them (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!
Process Failure Modes Effects Analysis
How do we perform a PFMEA?
#1: Identify the process or product that requires the PFMEA
Analysis …
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.

How to perform a PFMEA

• Column 3 – Brainstorm and list all the “effects” of the

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
