Six Sigma….. Udemy

[Flelm]

In my opinion, Six Sigma has diminishing returns outside of manufacturing, and specifically high volume, process-based manufacturing. It's about process improvement, and reducing the amount of defects to less than a six-sigma (standard deviation). For service-based industries I don't believe it's that useful in practice, although I'm sure you can use some of the techniques.

Personally, I think white belts are fine for an introduction to the concept, but they're what I would expect from a supervisor or line manager that's either just starting out or just starting to work towards a management track. A yellow belt or ideally green belt are where you actually start to get good training and hands-on usage on the practices. If you're looking to stay in education, I'm not sure Six Sigma is helpful to you. If you want to transition to manufacturing, I would aim at a yellow belt at the least, and watch for accreditation as commented earlier.
