Six Sigma is a statistical measure expressing how close a service comes to meeting it’s quality goals

The Goal:The Goal:To achieve superior quality

•Quantitatively, this means that the average process generates less than 3.4 defects per million opportunities.

Lean & Six Sigma

1) Lean does not address bringing a process under statistical control

2) Six Sigma cannot, alone address improving the speed of process

Fusing Lean and Six Sigma is Required for Two Reasons….

Lean and Six Sigma

Six SigmaSix Sigma LeanLeanGoal Identifies and eliminates complex

sources of variabilityEliminates simpler sources of variability and creates flow by

eliminating wasteTargets 85%--90% 20%-50%

Application Where statistical process control is needed

Where standard work is needed

Approach Expert Driven- requires thorough understanding of experimental design

and applied statistics

Front Line Driven-Utilizing the collective wisdom of point of care staff with Lean expertise guiding

Project Selection Source of the variation is unknownNo predetermined solutions exist

Driven by value stream map

Length of Projects

4 months to 1year 1 week to 3 months

Training Technical classroom training/learn by doing
