Chapter 2. Six Sigma and Visual Six Sigma

This chapter introduces the key ideas behind Six Sigma and Visual Six Sigma, where our focus is on the latter. Six Sigma is a huge topic, so we only have space to mention some of its essential ideas. There are already numerous well-written books and articles dealing with the many and diverse aspects of Six Sigma as commonly practiced.[] We also note that, today, digital tools (software, databases, visual media, etc.) are leveraged extensively in Six Sigma initiatives.[]

Our goal in this chapter is to provide an overview of Six Sigma so that you start to see how Visual Six Sigma fits into this picture. However, it is worth pointing out in advance that you can gain an appreciation of the power of visualization techniques only by working with data that relate to real problems in the real world.
