About Certified Lean Six Sigma Black Belt (CLSSBB) Certification 

To apply the Six Sigma technique to particular tasks, Black Belts work under the supervision of Master Black Belts. They devote all of their valuable time to Six Sigma. They are mainly concerned with Six Sigma project execution and exceptional leadership with special assignments, while Champions and Master Black Belts are concerned with recognizing Six Sigma projects/functions. A Certified Lean Six Sigma Black Belt (CLSSBB) is a person who is well-versed in the Lean Six Sigma Methodology and leads improvement projects on a full-time basis.

Objectives of the Certification Exam

As a management philosophy, Six Sigma has assisted thousands of practitioners worldwide in reducing cycle times, increasing efficiency, and improving process quality and execution. The following competencies are established through this exam:

  1. To begin, the ability to efficiently deliver business benefits.
  2. Second, expertise and skills are required to improve the efficiency of processes and workflows.
  3. Third, expertise is in high demand in the industry (Analytical, Statistical, Facilitation, Project Management Skills, etc.)
  4. Deal training for a leadership position is also included.
Who is eligible for this exam?

Anyone heading a Lean Six Sigma process improvement project or wants to learn the concepts involved to advance their professional skills. It refers to employees, line supervisors, administrators, and directors in production, operations, customer service, engineering, information technology, marketing, logistics, sales, efficiency, buying, health care, education, and health and safety. Furthermore, those who work as full-time Project Managers should obtain the credential. 

What are the requirements?

The CLSSBB Certification has no prerequisites, but it is strongly recommended that you complete the E-Course since most exam questions are taken from the E-Course.

Benefits/Importance of certification

The following are some of the reasons why you should obtain six sigma certification:

1. Thorough understanding of the procedure

As a certified Six Sigma Black Belt practitioner, you will be able to interpret the DMAIC (Define, Measure, Analyze, Improve, Control) process in greater depth than you did as a Six Sigma Green Belt or even lower Six Sigma Belt. Black Belts now qualify you to take your understanding of these steps to the next level and provide you with the expertise to complete them correctly.

2. Accomplishment of new difficulties

From a different perspective, Six Sigma Black Belt certification would open the door to new and exciting challenges and a large extent, to quickly ignore them. It's as if you were serving under a single team, and on the operation, this Six Sigma certification will initiate cross-team and team project management, which will add complications.

3. Excellent possibilities

Assume we have a Green Belt and are working as an influential team member on a quality-related project. With Black Belt certification, you can now move up the corporate ladder and work as a Project Manager rather than reporting to one. Furthermore, the Six Sigma certification enhances your leadership abilities.

4. Improving your technical skills

As a Project Manager, you are expected to complete cross-team projects without conflict and to effectively communicate to everyone, even in layman's terms, what we are doing and what it takes to get the job done, even if you are not a Six Sigma expert. This is explained in such a helpful way in the Six Sigma Black Belt certification that you can co-relate to the most basic examples to make someone quickly conclude anything.

To advance in your career and manage a team of Green Belt professionals, you must have a strong command of a wide range of statistical techniques. During your Black Belt certification training, you will correctly work on several advanced data analysis tools on relevant data, allowing you to gain a more helpful perception of these tools and learn them faster.

5. Market Research

You are no longer expected to be a workhorse; instead, you are expected to have a firm understanding of your competitors and even conduct adversary analysis to explore new strategies and areas to seize more market share. Your analytical tools learned during your Black Belt certification training will come in handy here.

6. Ascending to the Position of Business Leader

You are qualified for fixing your company's views and demands to the workforce with the Black Belt credential, as they will finally be working on quality management and growth.
