CLSSBB Certified Lean Six Sigma Black Belt (CLSSBB)

CLSSBB Certified Lean Six Sigma Black Belt (CLSSBB)
Black Belts operate under Master Black Belts to apply Six Sigma methodology to specific projects. They devote 100% of their valued time to Six Sigma. They primarily focus on Six Sigma project execution and special leadership with special tasks, whereas Champions and Master Black Belts focus on identifying projects/functions for Six Sigma. Certified Lean Six Sigma Black Belt (CLSSBB) is well versed in the Lean Six Sigma Methodology who leads improvement projects, typically in a full time role. A Certified Lean Six Sigma Black Belt holder possesses a thorough understanding of all aspects within the phases of D-M-A-I-C. They understand how to perform and interpret 6 Sigma black belt tools and how to use standard principles of Lean. The Certified Lean Six Sigma Black Belt (CLSSBB) 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 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.

The exam comprises of 150 Multiple Choice Questions out of which the candidate needs to score 75% (112 out of 150 correct) to pass the exam.
