DMAIC Six Sigma & Lean Six Sigma
Difference between DMAIC Six Sigma and Lean Six Sigma
Lean Six Sigma
Goal: Reduction of waste in all of its forms throughout
the operation
Method: Set operation to order using 5S and visual factory; identify
where in the material and information flows waste exist and
eliminate it.
Measure: Operational costs.
Industry: Manufacturing
DMAIC Six Sigma
Goal: Reduction of variation in all processes of the
operation
Method: Search for differences in performance between groups, within
groups, and over time to identify primary contributions of
variation; develop additional understanding of multivariate causes
by studying relationships between process inputs and outputs; put
controls in place to minimize the contribution of input variation on
output variation.
Measures: Variance, standard deviation, Process Capability (Cp and
Cpk), sigma value, operational costs.
Industry: Process environments
