Lean and Six Sigma gain benefit from each other
LEAN is centered on the concept of flow.
A major inhibitor to flow in a business process is defects.
Six Sigma is uniquely positioned to reduce the variation that causes
defects.
SIX SIGMA is centered on reducing variation to eliminate
defects.
A major cause of variation in a business process is complexity of nonvalue
added waste.
Lean is uniquely positioned to reduce complexity.
It is for this reason that Lean Six Sigma is so powerful.
