Yes, there is a concept called 5 Sigma. Sigma levels are used to measure the defect rate in a process. 5 Sigma corresponds to about 233 defects per million opportunities, reflecting a high level of quality control but not as stringent as 6 Sigma, which allows only 3.4 defects per million. Reaching 5 Sigma requires rigorous quality management and continuous improvement practices.

FAQs & Answers

  1. What does 5 Sigma mean? 5 Sigma refers to a quality management measurement indicating approximately 233 defects per million opportunities, signifying a high level of quality control.
