Six Sigma Yellow Belt certification provides an overall insight into the techniques of Six Sigma, its metrics, and basic improvement methodologies. A yellow belt must know how to integrate Six Sigma methodologies for the improvement of production and transactional systems to better meet customer expectations and bottom-line objectives of their organization. A Yellow Belt typically has a basic knowledge of Six Sigma, but does not lead projects on their own. The Yellow Belt is needed to gather data, participate in problem solving, and add their expertise to the exploration process.
