Six Sigma is a technical, data-driven quality improvement program. A Black Belt is one step above a Green Belt, and one below a Master Black Belt, which is the highest level. Earning a Black Belt is challenging, but there are good reasons to make the commitment: a bump in salary, plus the opportunity to take on more responsibilities. Here's what's involved—it's a respected credential, but it isn't for everyone.

Six Sigma Training
At the Black Belt level, students are expected to already have a Green Belt certificate or at least three years of work experience in the field or they must have completed two Six Sigma projects, according to the American Society for Quality (ASQ). Experience must be full-time paid work. Co-ops, internships, and part-time jobs don’t apply.

What Is Six Sigma?
Six sigma is a set of methods and 🐽to꧅ols that individuals and companies can use to improve processes.
What Is the History of Six Sigma?
Carl Friedrich Gauss (1777-1855) was the first to define a measurement standard using the concept of the normal curve. In the 1920s, Walter Shewhart showed that sigma is where a process needs to be improved. In 1986, two Motorola engineers, Bill Smith and Mikel Harry, invented Six Sigma as a method. In 1995, General Electric used Six Sigma as its central business strategy.

In the financial sector, American Express, Bank of America, Bank of Montreal, and Capital One have used 澳洲幸运5官方开奖结果体彩网:Lean Six Sigma. In the information technology space, 3M and Dell have used Lean Six Sigma. The Department of Defense and the U.S. Navy have used Lean Six Sigma, too. Governments have also used Lean Six Sigma, from King County, Washington to the Colorado Department of Transportation.
The Bottom Line
Getting a Six Sigma Black Belt is no easy task, so it's important to know what you're getting into, and who this credential is designed for. A Black Belt is appropriate for senior technical roles, such as project managers, quality managers, operations managers, and new product engineers or managers. On the other hand, for junior roles in technical industries, a Green Belt would probably suffice.
