The Six Sigma method in manufacturing can be difficult but there are a multitude of courses available that make it look easy. The first major decision, after of course you choose the best provider for you, is which level of Certification would best match your goals. One major difference between a Six Sigma Black Belt and a Six Sigma Green Belt is the amount of knowledge provided. Because the Black Belt certification is longer and more involved, students are given more knowledge about the six sigma method.

Six Sigma Green Belts are taught the basics of Six Sigma. Green Belt course material includes: project definitions, project selections, process mapping, measuring systems, capability analysis, process control plan and project reviews. The Six Sigma Green Belt students will take in a lot of information but it is in a condensed form when compared to the Black Belt students.

Both the Green Belt and the Black Belt positions are very challenging and lots of information is exchanged. It can get confusing, but once students gain actual experience in the real world, all of the pieces of the puzzle come together. The Six Sigma Green Belts are the ‘worker bees’ of most Six Sigma operations. They work under the Black Belts, who oversee the projects. When choosing a Six Sigma Black Belt Certification provider, it is best that they require a full project to be completed. This way, you will gain some ‘real world’ experience even during your training so that all the pieces will fall into place more quickly.

It then goes into breaking down the DMAIC (Define, Measure, Analyze, Improve & Control) Process, explaining each step so that all Green Belts are familiar with the various processes and Six Sigma Methodology. Within all of these categories, there is specific and detailed information available that needs to be known, including the actual steps and details involved in a complete Six Sigma Process.

Originally developed by Bill Smith at Motorola in 1986, the Six Sigma Training program was created using some of the most innovative quality improvement methods from the preceding six decades. The term "Six Sigma" is derived from a field of statistics known as process capability. The term 6 Sigma refers to the ability of manufacturing processes to produce a very high proportion of output within specification. Processes that operate with "six sigma quality" over the short term are assumed to produce long-term defect levels below 3.4 defects per million opportunities. Six Sigma's goal is to improve overall processes to that level of quality or better.
