For the vast majority of companies, a Sigma Level of 6 should be the goal but don’t expect to achieve it. It’s more important to understand how much your customer is willing to pay for quality — and that the desired sigma level can be met at that cost. Conclusion Sigma Llevel is...
Design Exploration优化具有Design of Experiments、Response Surface、Response Surface Optimization、Direct Optimization、6_Sigma等功能模块,能够进行基于实验设计法的响应面分析、响应面优化、最大目标优化设计和6_Sigma可靠性分析等,图3是响应面分析相关分析内容示意,图4是最大目标优化相关设置选项示意。
先分别算出DPO 和 DPMO之后用 DPMO到 Z-table里面找相应的长期和短期sigma level

Learn what is Six Sigma methodology, tools, methods for improving business processes and reducing defects through a data-driven approach.
Sigma indicates a wide scattering of the readings. If the mean is the required quality standard of a particular process or product, then One Sigma quality is not very good. The higher the number, the closer the readings come to total perfection. At the Six Sigma level, there are only 3.4...
