Region BA6LinkingPinsBusiness Area InitiativesIt unifies the initiatives and provides a common language which all people can understand and speak.23How Do We Improve CapabilityOur Outputs (Ys) are determined by our Inputs (Xs). If we know enough about our

19、Xs we can accurately predict Y without having to measure it. If we dont know much about our Xs, then we have to resort to inspection and test (non value added operations).By knowing and controlling the Xs, we reduce the variability in Y, which decrease the number of defects, improves RTY, cycle time

20、, etc. We can also eliminate or reduce inspection, test, and rework.24The Sources of Six Sigma Qualityby controlling.by designing.ContinuouslyReduceProcessVariabilityTighter Upper& Lower LimitsTarget valuesLower Limits1.
