Since the mid 1980’s, Sig Sigma has been offering tools and techniques to reduce process and organizational variations within manufacturing and heavy industries. The concept of Six Sigma evolved from total quality management methodology of the 1950’s. Lean was developed by Toyota to reduce costs and eliminate non-value added activities and Six Sigma was developed by Motorola to reduce process variability and capture metrics for statistical analysis [1].
