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.
Exams are online and proctored based, using a webcam and a reliable internet
connection exams can be taken anywhere and anytime.
The total duration of the exam is 3 hours (180 Minutes)
No external sources of information may be accessed during the exam held via
ProctorU. Further details of the materials permitted are provided:
Identification Proof
Scientific Calculator will be provided via ProctorU while Exam Session is in
progress.
If a Candidate does not pass the exam in the second (2nd) attempt, the candidate
must wait for a period of at least fourteen (14) calendar days from the date of
their attempt to retake the exam for third (3rd) time or any subsequent time.
The exam can be taken any number of times.
The Certified Lean Six Sigma Black Belt (CLSSBB)™ Certificate is valid for life.
