The Variation Mode and Effect Analysis, or VMEA, is a systemic study of the Variability causes of a Process and the means to prevent them.
VMEA is without a doubt the most important tool of the “Analysis” Phase.
All the preceding activities flow into the VMEA. The essence of what comes next depends on it.
The Six Sigma tools are powerful especially when they are used in their complementarity.
VMEA is the center or the “pivot” of the project.
Almost all the successfull DMAIC projects have included a well-conducted VMEA analysis.
Such analysis highlights the points which require your attention, even those of which you are not even aware.
The savings in terms of time and energy can be considerable!
