Six Sigma Strategy

Strategy of improvements through Six Sigma can be summed up as any one or combination of the following 3 S.

SHIFT: If the central tendency of the process is outside the specification limits and spread is well within these limits, we need to Shift the process within these limits.

SHRINK: If the central tendency of the process is within the limits but the spread of the process is beyond the limits, Shrink the process within the limits

Stabilise: If both central tendency and spread are as desired, stabilise the process by monitoring, standardizing and documenting the process.
