Many Six Sigma prep programs will simply offer access to personal study materials such as practice tests or textbooks on-demand, with a few pre-recorded lectures thrown in. GreyCampus offers these features as well in their Online Self Learning program; however, what really makes them unique from other educational resources is their other packages that incorporate live instruction from an experienced Six Sigma professional.

Frequently Asked Questions about Six Sigma Certification

What are the different levels of Six Sigma certification?

According to the Six Sigma website, there are five Six Sigma certification levels. Here’s a brief rundown of each level:

  • Six Sigma White Belt certification only takes a few hours to complete. Certification means that you understand some of the definitions and general concepts regarding Six Sigma methodology.
  • Six Sigma Yellow Belt certification takes a few days on average to complete. It is slightly more involved than White Belt certification and qualifies you to work on Six Sigma projects under a Green Belt or Black Belt.
  • Six Sigma Green Belt certification takes around ten days on average to complete. Green Belts are qualified to run many small projects with teams made up of Yellow Belt and White Belt certified individuals. They also work on larger projects with the help of Black Belt certified individuals.
  • Six Sigma Black Belt certification takes twenty days on average to complete. They are extremely well-versed in the methodology and can handle projects with much larger sizes and scopes. Additionally, they usually mentor Green Belt, Yellow Belt, and White Belt individuals.
  • Six Sigma Master Black Belts are considered the most capable and well-trained out of all Six Sigma practitioners. They can handle multiple projects at once and can train Black Belts, Green Belts, Yellow Belts, and White Belts.

Which Six Sigma certification is best?

Depending on your company’s needs, your time and money budget for education, and your desired career path, different Belt levels will have different benefits. For many small-scale projects, Green Belt certification is sufficient; however, Black Belt or Master Black Belt certification are excellent additions to your resume that can also greatly increase your salary.

Which companies use Six Sigma?

Some noteworthy companies that have implemented Six Sigma methodology to optimize their project management include GE, Motorola, Texas Instruments, Bank of America, and American Express.

How do managers use Six Sigma?

The best use of Six Sigma for managers involves taking its focus on removing defects and optimizing small aspects of a process and applying that to people instead. It isn’t as effective in this way as it is for manufacturing, engineering, or healthcare, but it can help to set you apart from other management candidates.
