What is the main focus of the 6 Sigma methodology?

The main focus of the 6 Sigma methodology is on minimizing defects in processes. This approach is fundamentally about improving quality by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes. The framework utilizes five key phases known as DMAIC: Define, Measure, Analyze, Improve, and Control, which guide teams in making systematic improvements to processes. By concentrating on reducing defects to a target of no more than 3.4 defects per million opportunities, 6 Sigma aims to enhance overall efficiency and customer satisfaction by providing a high level of quality in products and services. This methodology is widely used across various industries to streamline processes and ensure reliability, ultimately leading to reduced costs and improved performance.
