ASQ – CERTIFIED SIX SIGMA BLACK BELT
The Certified Six Sigma Black Belt is a professional who can explain Six Sigma philosophies and principles, including supporting systems and tools. A Black Belt should demonstrate team leadership, understand team dynamics and assign team member roles and responsibilities.
Black belts have a thorough understanding of all aspects of the define, measure, analyze, improve and control (DMAIC) model in accordance with Six Sigma principles. They have basic knowledge of lean enterprise concepts, are able to identify non-value-added elements and activities and are able to use specific tools.
Note: Six Sigma Black Belt certification requires that you complete at least one Six Sigma project and submit a project affidavit. Review frequently asked questions regarding projects and the affidavit/verification.
Here are the experience and exam specifics for the Certified Six Sigma Black Belt.
Six Sigma Black Belt requires two completed projects with signed affidavits or one completed project with signed affidavit and three years of work experience in one or more areas of the Six Sigma Body of Knowledge.
For more information, please see the list of Six Sigma Project Affidavit FAQs. You do not need to be a Certified Six Sigma Green Belt.
Work experience must be in a full time, paid role. Paid intern, co-op or any other course work cannot be applied towards the work experience requirement.
