Application of six sigma methodology for process design quality improvement

This paper deals with application of Six Sigma methodology in process design. Using an example of compressor-housing machining process design and development at the Cimos facility in Buzet the possibilities for some Six Sigma tools applications are explained. The primary tools are the process map and the cause and effect matrix. A modified process design flow with incorporate applications of the mentioned tools are shown, a comparison of the old and the modified process design flow is made and the obtained results are discussed.
