The main feature of the 6 Sigma model compared to other quality management methods is its focus on individual processes and variations in them. Unlike TQM and ISO 9000, which cover all business processes and are focused on overall quality improvement, Six Sigma is focused on processes and defect elimination goals.

A distinctive feature of the 6 Sigma concept is its focus on statistical analysis and the use of data in the decision-making process. Unlike the ISO 9000 approach, which is based on the construction of a quality management system, and TQM, which focuses on the general principles of quality, Six Sigma is based on mathematical analysis to identify the causes of defects and variations, as well as the development and implementation of measures to eliminate them.
