Hi, I am Lisa. I am a corporate person and I have looking further steps to get a six sigma black belt certification. I have heard that working on a black belt project is mandatory before exam. Is that true or any other ways exists?
Yes. It is mandatory Lisa. Otherwise you are not eligible for the exam. For being a certified professional definitely the project working experience is required and I am sure there are no other ways exists. If you need more information, you can visit the reference link below,
