As a certification body, the Management and Strategy Institute (MSI) set's standards on which skills are to be tested and understood by individuals applying for certification. We set these standards through a program we call the Six Sigma Quality Standards (SSQS) program. These international quality standards are published below and allow you the opportunity to review the standards online. MSI considers these standards to be open-source and public comment on them is welcome. The below documents represent the minimum standards required for certification at the Black Belt, Green Belt and Yellow Belt level through MSI. To download the PDF, please click on the link below:
