Six Sigma is a data-driven methodology used to improve processes and eliminate defects. It was developed at Motorola in 1987 and uses a define-measure-analyze-improve-control (DMAIC) cycle. Green and Black Belts are certified to lead Six Sigma projects through this cycle, first defining problems, measuring key aspects, analyzing root causes, improving processes, and controlling changes. The document provides an overview of Six Sigma and its goals, deployment, methods like DMAIC and DMADV, integration with other methodologies, and the activities involved in each stage of the DMAIC cycle.

7. Methodology Integration The matrix below defines how various methodologies align

8. Process Design Flow Recognize Define Measure Analyze Improve Control

16. Review Y and X Measures

17. Process Measurement Example Delivery Time in Days Critical Customer Requirement = 9.4 days Defects: Service unacceptable to customer Number Orders Filled Variation in results 1 2 3 4 5 6 7 8 9 10 11 12

21. Analyze Current Process Use symbols and colors to help you analyze the current state
