Master Black Belts

Master Black Belts are generally those Black Belts who have successfully completed a large number of Six Sigma projects and are experts in using Six Sigma tools and techniques.

They are generally responsible for training and mentoring entire Six Sigma Teams. They also assist the Six Sigma leader and Champions in project monitoring. They also work with the process owners to ensure that the plans are implemented, targets attained and progress is tracked.

They work together sharing data regularly.

Black Belts

The Black Belts are the lifeline of any Six Sigma initiative. They are mainly responsible for leading any improvement projects. They are involved full time with the project.

They are responsible for undertaking project planning and completion. They can typically undertake 4 or 5 projects every year with a wide range of savings. They are also responsible for coaching and guiding Green Belts in their project areas. They guide them to use the different Six Sigma tools and techniques.

Green Belts

Green Belts are those members who are trained in Six Sigma tools and techniques. They are responsible for projects at their functional level.

They undertake the project responsibility along with their daily activities. They would generally undertake projects which are smaller and which can bring about improvements with the guidance of Black Belts.

Process Owners

The process owners are responsible for specific processes. The Black Belts will undertake the improvement project with the participation of process owners.

By involving them, Black Belts ensure that requirements of processes are met and appropriate changes done to improve overall productivity and utility of the process. When changes are brought about in a given process the process is handed over to the process owners by the Black Belts or the Green Belts.

For example, if there is an accounts manager taking care of the accounting department, he will be the process owner of that entire accounting process.

This is the typical structure of the Six Sigma organization. Depending upon the size of the organization, the roles may be assigned to different people.
