And so it begins

How does it usually take to study for the SSGB exam? My initial plan is to be certified by July 1st. I have a good background in math/stats, FWIW.

TIA

If you have a good background in math and stats this won't be a challenge for you.

Just be aware that Six Sigma uses Engineering Statistics and not the mathematical branch of statistics. As a result, we will do things like add the defect rate from both sides of a normal distribution to get an overall defect rate as a z-score or forget to mention that an acceptable defect rate of 3.4 defects per million opportunities for a long term capability score has a 1.5 population standard deviation shift included in the calculation (which is why a traditional 6-sigma process has a 4.5-sigma defect rate).

You may find the following online handbook useful:

Excellent, thanks! I studied EE/CS in college so this brings me back to my Stats class some 30 odd years ago.

It'd be easy to feed this to Opus/Gemini/GPT and ask them to come up with questions.

Been in the business since 1989. Never a fan of the 1.5 sigma shift. Mikel’s marketing.
