If you have been trained by ProgressivEdge, Inc., no. You can simply take the LSS Black Belt Upgrade we offer which is an eight-day course over a period of four months. If you have been trained elsewhere, we will conduct an interview with you, usually by phone, and discuss the content of the training you have received to determine whether you have been given all of the tools you need for the Black Belt Upgrade course. All LSS Green Belt courses are not the same. Some are missing important tools while others do not include a hands-on approach or require the completion of a project. To earn your certificate from ProgressivEdge, Inc., we need to be sure you get the training you really need to implement LSS effectively.
