Six Sigma is a disciplined, data-driven methodology for reducing variation in any process. The Six Sigma methodology–driven by the DMAIC (define, measure, analyze, improve, control) process–is executed by Six Sigma green belts, Six Sigma black belts, and overseen by Six Sigma master black belts. Green belt training participants receive a subset of the more advanced black belt training course, with an emphasis on developing a structured problem-solving strategy for addressing business improvement projects by using intermediate quality tools within the Six Sigma methodology.

Referrals from our Six Sigma Green Belts:

“I thought the class had a lot of information that pertains to my job.  This also  answered some questions that I had for understanding the statistics.”

-Six Sigma Green Belt, KTH Leesburg Products

“Very well organized. Excellent instructor.  He easily kept your attention and made the class interesting.”

-Six Sigma Green Belt, BASF

UAH CMER-ATN’s Six Sigma Certification

The OSSS curriculum is Accredited by the International Association for Six Sigma Certification (IASSC) meaning the OSSS Belt courses are highly aligned to the IASSC Bodies of Knowledge. In addition, a study conducted in coordination with Bearing Point Consulting determined that the OSSS curriculum matched the DMAIC ASQ Body of Knowledge to a degree greater that 90%.

Dr. Sampson Gholston, course instructor, is an IASSC ACCREDITED TRAINING ASSOCIATETM
