I currently work in semiconductors (research) and I am interested in earning my Lean Six Sigma certification, possibly through a university online class. Has anyone gone through the process? If so, what is the level of difficulty to obtain a green belt? I have a solid background in statistics. Also, does Lean Six Sigma make the most sense for possible employment in semiconductor manufacturing or a job which requires a knowledge of statistical quality control? Would six sigma by itself suffice or would I better spend my time learning some statistical software such as JMP or Minitab? Any advice will be greatly appreciated. Thanks.
