Lean Six Sigma students learn a combination of lean manufacturing methodology and Six Sigma methodology. Lean manufacturing seeks to reduce the amount of inventory on hand, while Six Sigma methodology aims to reduce the frequency of product defects or process errors.
Lean Six Sigma training coursework varies widely; however, all training courses teach the five-step process improvement methodology known as DMAIC. DMAIC is an acronym for define, measure, analyze, improve and control; this represents the primary features of Lean Six Sigma training.
The central theme of the DMAIC steps is to find the root cause of product defects associated with a manufacturing process and then use statistical and mathematical process control techniques to evaluate, analyze and improve product quality. This process is complicated, which is why trained Lean Six Sigma professionals are so valuable in the corporate world.
Six Sigma training course completions result in one of the following Six Sigma certifications: Six Sigma White Belt; Six Sigma Yellow Belt; Six Sigma Green Belt; Six Sigma Black Belt and Six Sigma Master Black Belt. The White and Yellow Belts are for novices, while the Master Black Belt is the highest level achievable.
Many mainstream universities and online institutions offer Lean Six Sigma online training and certifications. Some brick-and-mortar institutions offer online solutions as a part of their continuing education or extension programs.
