What is a Yellow Belt?

Originally, Yellow Belts were individuals that were trained while working on a project with a Green or Black Belt. However, more companies are requiring formal training for Yellow Belts. In most cases, the Yellow Belt has some expertise in the process that is being improved, so he or she needs a basic understanding of Six Sigma in order to support the Green Belt or Black Belt working to improve the process. Yellow Belts do not have the knowledge needed to complete projects.
