Six Sigma Roles and Responsibilities

Six Sigma has a martial arts convention for naming many of its professional roles. The chart below describes how these roles are typically defined.

Leaders and Champions usually receive high-level training on the technical aspects of Six Sigma and specific training on how to lead an initiative. At the “Belt” level, each candidate is assigned an initial “training project” that he/she will work on during the formal training period. Candidates attend classroom training for a week, work on their projects for three weeks, return to class for another week, and so on until they have acquired all the skills appropriate to their role.
