As trainers and/or mentors of Six Sigma, we are responsible for teaching the right concepts.

It is easy to fill up the Six Sigma training materials with statistics. Is it worthwhile spending 2 out of 3-4 weeks of a Black Belt training on statistics? 2 weeks of statistics is barely touching the surface of the subject when you consider the fact that professionals spend years studying it. The result is predictable confusion and misuse of tools.

In contrast, it’s much more effective to focus on statistical thinking, especially around two critical concepts: variation and stability. In 1-2 days, students will develop far more statistical thinking from the Red Beads and Funnel experiments that Deming used to illustrate these concepts.
