1st Stage: Process Delineation |
Define the process, its boundaries and functional characteristics, response variables, independent variables and their inter-relationships. |
2nd Stage: Metrology Characterization |
Define the measurement system needed to evaluate the responses and quantify its variation. |
3rd Stage: Capability Determination |
Determine the current ability of the process to meet customer specifications and predict its stability, capability and Sigma performance at the process' optimum levels. |
4th Stage: Optimization |
Reduce the sources of variation through statistically designed experimentation and optimization techniques. |
5th Stage: Control |
Set up a complete system of preventive control for the independent variables. Mistake-proof the process against defects and monitor the response variables. |
