FMEA RPN and Process Sigma

eLearning Price: $ 0.00

Full Description

This Nano sized course introduces FMEA, RPN, and converting RPN to Process Sigma Level. FMEA (Failure Mode and Effects Analysis) is a powerful tool for identifying, defining, and quantifying root causes to operations issues. The RPN (Risk Priority Number) is calculated by multiplying the severity score times the occurrence score times the detection score. The RPN quantifies the impact of a potential root cause providing the means to rank the root causes. This is how we separate the vital few from the trivial many. Converting the RPN into a Process Sigma Level is shown in a handy table. When processes cycle infrequently the FMEA, RPN, and conversion to Process Sigma level provide the means to quantify the improvement.
  • The concept of FMEA is introduced.
  • How to use the FMEA worksheet is explained in detail
  • How to calculate the RPN is explained in detail
  • How to convert a reduction in RPN from Current State to Future State as a Process Sigma Level is explained
  • Examples are provided to illustrate the points

How Much Data do I Need?

That is an excellent question that can either have an exacting answer or one that is ambiguous.  Formulas exist to calculate an exact answer to the question except that until you collect some data you won’t know the values for some of the variables in the equation.  In both cases, either...
