The IASSC, Villanova, and ASQ Six Sigma Black Belt exams all require knowledge of the Founding Fathers of Six Sigma and the Quality Movement. These should be easy points that you pick up. What follows is a great reference for you to take with you to the test.

Six Sigma was originally developed by Motorola – first by Bill Smith, then Mikel Harry as a general approach to measuring quality in business performance terms. Over the years, especially in the 1990s continuous improvement tools and methods were developed by Deming, Juran, Shewhart, Ishikawa, Shingo and Taguchi.

Now it has evolved be a project driven approach to process improvement that follows the five-step process known as the DMAIC cycle. This process has been used by the world’s best companies to save and make billions of dollars.

I would suggest studying these last after you’ve mastered the rest of the test. At least it was easier for me to understand the impact of these historical figures after I already knew (and had used) the techniques they had invented. This is a studying technique known as anchoring – fixing new knowledge into your memory by ‘anchoring’ it to existing knowledge.

I’ve added links to the techniques that these men invented. If you are not familiar with them, study those, too!

The character posting for Crosby is actually Harry.

Crosby had 12 points, which is why Deming decided on 14; thirteen not being a good number.

A google search has many entries suggesting Bill Smith is the father of six sigma. Your text says “some say Mikel Harry is…”. While your text is not wrong, it’s not very correct either.
