The primary goal of Six Sigma methodology is to minimize defects and variability in processes. This approach is fundamentally dedicated to improving the quality of output by systematically identifying and eliminating the causes of errors and reducing variability in manufacturing and business processes. By focusing on reducing defects to a level where they occur at most 3.4 per million opportunities, Six Sigma ensures that processes are dependable and efficient, ultimately leading to increased customer satisfaction and business performance.

This emphasis on minimizing defects directly contributes to process optimization and provides a structured framework for problem-solving through the use of statistical tools and techniques. Achieving such high levels of quality not only enhances the operational efficiency of an organization but also lowers costs associated with rework, scrap, and warranty claims, thereby increasing profitability. Such outcomes are core to the philosophy and application of Six Sigma, making this option the most aligned with its fundamental objective.
