What is Six Sigma?

Six Sigma is a system and methodology for process improvement that focuses on eliminating problems and defects in product or service quality. Process changes are based on the results of data analysis and seek to achieve measurable quality and financial improvements. 

Six Sigma provides professionals with a structured problem-solving framework, statistical tools, and techniques to drive continuous improvement in organizations. Certification levels use martial arts terminology and each have defined roles within an organization. For example, Six Sigma Yellow Belt Certification means that this person is new to the world of Six Sigma and has a minimal role, interest, or need to develop foundational knowledge while Six Sigma Black Belt Certification means that this person is qualified to lead individual Six Sigma project execution.
