BB vs. CQE
Great questions, and great dialogue! I have to agree with GaryC and Benjamin. Despite its many weaknesses, I have to agree that Six Sigma brings a formal process and universal language to quality improvement that is sorely lacking in the CQE requirements. Of the two exams, the CQE was definitely the more challenging for me. However, part of the reason the CSSBB was so much easier was because I had the CQE background. The overlap is significant.
Personally, I find the two exams (and more importantly, their bodies of knowledge) complimentary and highly synergistic. Understanding the quality tools to the level of the CQE shores up the abilities of BBs who were trained through substandard programs (and believe me, there are a LOT of them out there). Similarly, the DMAIC process, Lean concepts, and DfSS knowledge helps to focus and strengthen the effectiveness of any quality engineer. Which would I prefer to hire, the CQE or CSSBB? The one most interested in pursuing the other BOK and certification as quickly as possible.
