核心理念：

• 目标是每百万个机会中缺陷不超过3.4个，即达到六个标准差的水平。
• 采用DMAIC（定义-测量-分析-改进-控制）和DMADV（定义-测量-分析-设计-验证）两大流程模型，进行持续改进和新产品开发。
• Core concept:
• 
  
• The goal is to have no more than 3.4 defects per million opportunities, reaching a level of six standard deviations.
• Adopting two major process models, DMAIC (Definition Measurement Analysis Improvement Control) and DMADV (Definition Measurement Analysis Design Verification), for continuous improvement and new product development.
