I have earned both a Lean Six Sigma Yellow Belt and Green Belt Certification (the latter upon completion of a Green Belt project in addition to the coursework) and have saved my company thousands of dollars in material costs and by solving process problems in the areas of Accounting, Manufacturing, Retail, Janitorial Services, and Donation Processing. […] I found this course very thorough. The instruction was loaded with case studies, which are extremely helpful in understanding the concepts. The instruction videos were excellent and the instructor Holly Ott was very responsive to questions. She answered any course questions on a daily basis, and students have the opportunity to share ideas with each other and answer each other’s questions as well.
