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
