Recently, I managed a project concerning Lean Six Sigma, which is a brand new name to me. Therefore, I collect some material on this topic and try my best effort to learn it. Here we learn from a bilingual format for a better understanding.

Firstly, a basic Introduction to Lean Six Sigma

Why Blend Lean and Six Sigma ?

为何将精益与六西格玛结合起来?

• Six Sigma is far better placed to deal with complex quality issues and reduce process variation. It has a very capable toolset to achieve this.
