It is a comprehensive approach that certainly includes the optimization of operational processes emphasized in the Six Sigma framework, but operational processes represent only one small component part of the much broader focus of TQM. If there is a disadvantage to TQM, it would be in connection with the types of businesses or industries in which the standardization and optimization of operational processes is extremely important. In principle, those types of organizations and operations would benefit from the Six Sigma approach whereas industries and organizations in which operational processes are merely one component of a much broader set of variables would likely benefit more from the TQM approach (Robbins & Judge, 2009). The ISO 9000 approach to business management is one of the most successful modern business management systems, largely because it offers some of the advantages of Six Sigma and of TQM but with fewer potential negative consequences (George...

Like Six Sigma, ISO 9000 standardizes and optimizes operational processes, although through the use of objective standards rather than by reliance on certified team leaders and consultants. Like TQM, ISO 9000 provides a comprehensive management technique that is not limited to operational processes and operational management. The ISO 9000 approach is designed to improve all of the areas addresses by TQM and also allows processes and operations that benefit from technical standardization to be analyzed and improved for efficiency and maximum productivity wherever operational standardization and optimization are conducive to organizational success (Robbins & Judge, 2009).
