Implementing Six Sigma in Foundry Industry

摘要

Six Sigma Program is a highly disciplined process that helps product providers focus on developing and delivering near-perfect products and services. Basically, Six Sigma is a high-performance, data-driven approach to analyzing the root causes of business problems and solving them. More and more companies are realizing that they can achieve dramatic results by applying Six Sigma methods to tie the outputs of business directly to marketplace requirements. Six Sigma Program consists mainly of four phases: Measure, Analyze, Improve, and Control (MAIC). In measurement step, the appropriate parameter to be improved is selected based on customer's input. The current performance is accurately quantitative defined. The analysis step studies process capability and uses statistics tool to seek root causes and relationships. The improvement step typically stresses designed experimentation. In the control step, once the desired improvements have been obtained, the standard operating procedures are put into place to ensure the improvements are sustained. There is no doubt that a successful Six Sigma program must tie together with extensively application of computer technology, especially during the analysis and improvement steps. This paper will explore how a foundry can take steps to achieve Six Sigma quality level. The MAIC process is also discussed in detail.
