Lean Six Sigma Certificates

A certificate in Lean Six Sigma prepares you to eliminate waste or inefficiency in your workplace. Specifically, the certificates address how managerial employees can rid their systems of Defects, Overproduction, Transportation, Waiting, Inventory, Motion, and Overprocessing as it applies to engineering concepts. 

If you are a professional working in a hospital, a manufacturing facility, or any service industry, a certificate in Lean Six Sigma helps you learn the tools necessary to undertake continuous improvement projects aimed at reducing and eliminating waste, reducing project variations, improving customer satisfaction, and increasing your organization's bottom line.
