I have a Six Sigma Green Belt from my former employer. I also have a Certified Quality Auditor and Certified Quality Engineer. I work as a quality engineer and those are the most requested certifications in my field (At my curret level a SS Black Belt is often requested). I currently work in a role supporting external and contract manufacturing for my company. I find that the tools I learned in green belt training are very useful in my day to day work. I am required to support CAPAs and root cause investigations at my suppliers. Often these smaller companies do not have as many people with six sigma knowledge. I can support them by introducing the analysis and measurement tools learned during the green belt training. Hopefully in a few years I will be able to take black belt training to earn that last certification.
