What Does a Black Belt Do?

At the level of Black Belt, a person must be ready to handle multiple, critical roles in an organization’s ongoing process improvement efforts. They are highly valued because they can handle solving complex issues.

The following are some of the roles a Black Belt must take on.

Leadership. The buck truly stops with Black Belts. They guide project teams in process improvement efforts. That requires complete mastery of Six Sigma methods such as DMAIC (design, measure, analyze, improve, control) and DMADV (define, measure, analyze, design, verify). Communication and interpersonal skills are also key to success as a Black Belt.

Business strategy. One of the hardest tasks on any project is clearly defining a business goal from the outset – and then ensuring a project is completed in such a way that aligns with that goal. Black Belts work hand-in-hand with executives to ensure everyone is on the same page and that projects add value to the company.

Process improvement. Black Belts work as change agents. They seek to make a business more efficient and profitable. They also seek to create better products and services for customers. In short, they want an improved business world and they work hard to make that happen.

Belief in the system. At this level of Six Sigma, a person must have completely bought into what the methodology can achieve. That enthusiasm for Six Sigma will motivate others, as well.

Who Should Become a Black Belt?

Black Belts typically work at the manager or director level. Many, however, start Six Sigma certification training while still among the employee ranks.

Executives also can benefit from learning Six Sigma methodologies. The emphasis on eliminating defects from operational stages while also adding value to the customer, aligns perfectly with the goals of executive leadership.

Six Sigma also is a data-driven method of fostering change. Those with an interest in data analysis will find Six Sigma Black Belt certification both challenging and rewarding.

Who Can Benefit from Six Sigma Black Belt Certification?

If a person is considering becoming a Black Belt, they most likely have already earned their Green Belt. They can benefit greatly from taking the next step higher in certification.

Certification brings with it acknowledgment by peers that a person is capable and knowledgeable about delivering products and services. The certificate will position me to work on projects that are of interest to me and will show value to employers.”
