Abstract

Six Sigma is defined as a limit of 3.4 defects per 1 million opportunities for defects in products or service processes. A defect is defined as any product or service that is not acceptable to the customer. It can take organizations many years to achieve Six Sigma status. To achieve the required defect rate, organizations must make many improvements throughout the process of striving for Six Sigma distinction.
