六西格玛的那些带 “Belts”about Six Sigma
You may have heard about different “belts”in regards of Six Sigma but not clear what they mean. In this article, we will talk about all the roles related to Six Sigma in details and share some tips for people who are interested in pursuing career path related to Six Sigma.
黑带大师Master Black Belt (MBB)
An MBB is the person who is responsible for promoting and maintaining Six Sigma culture at corporate level. His/her major tasks usually include but is not limited to: trainings deployment, project selection, projects coaching, KPI definition and tracking, and regular communication with top management. In some companies MBB is positioned as a management role with a group of Black Belts as direct reports, yet in other companies it is considered as an expert role with only mentorship with Black Belts. Besides solid knowledge and experience with Six Sigma, a full set of soft skills, such as leaderships, communication skills, strategic thinking, are required for this role as well.
黑带Black Belt (BB)
BBs are expected to have strong statistical analysis and project management skills. They are usually full-time professionals responsible for leading DMAIC and/or DFSS projects, delivering Six Sigma trainings, and coaching other belts with less knowledge and experience. So, practically a BB acts as a project leader, a trainer, and a coach at the same time, and the workload allocation to these three roles varies company to company, sometimes even individual to individual. As for titles, some companies call their BBs project manager while in other companies they are engineers or specialists.
绿带Green Belt (GB)
GBs are usually part time Six Sigma professionals who are expected to contribute 20-30% workload to lead 1-2 DMAIC projects a year in their own departments. They are well equipped to handle projects that requires standard statistical analysis and with limited scope. The title for GBs depends on what their actual job is, mostly engineer or specialist.
黄带Yellow Belts (YB)
Normally, YBs don’t have to know much about statistics, they are only expected to understand the DMAIC logic and to solve simple problems with it in their daily work. As a result, YBs are not considered as Six Sigma professionals.
除了以上提到的以外，有些公司还有棕带、蓝带、和白带。一般来说，黑带大师 >黑带 > 棕带 > 绿带 > 蓝带 > 黄带 > 白带。
Besides what is mentioned above, some companies also have Brown Belts, Blue Belts, and White Belts. In general, MBB > BB > BrB > GB > BlB > YB > WB.
Every Six Sigma project has a coach. Usually a YB project has a GB/BB as coach, a GB project has a BB/MBB as coach, and a BB project has a MBB as coach.
Champion is the initiator and sponsor of a Six Sigma project, he/she is from the management team and is expected to have attended champion training. He/she initials project topics in his area with the help of MBB (or BB), help the project leader nominate team members, and supports the project team with recourse, guidance, and supervision.
Like other projects, a Six Sigma project requires a project team with necessary members. Those team members are nominated by champion, the person whom they directly or indirectly report to. They are supposed to be familiar with the project topic and have capacity (10-20% workload) to take over some project tasks distributed from the project leader.
