A term used to describe people who are trained in the Six Sigma concepts and basic tools. A company deploying Six Sigma may choose to designate project team members as Yellow belts after completing a required training course, or may use the designation for employees responsible for data collection for a Green Belt or Black Belt project.
The Yellow Belt body of knowledge is defined quite differently by different organizations. In some cases, it may represent only the most basic concepts and language of Six Sigma, with an overview of the D-M-A-I-C process. In other cases, Yellow Belts are trained in a more complete set of basic tools, typically representing 15 to 25 hours of training.
