Six Sigma is a disciplined, data-driven methodology used in business and process improvement. It aims to reduce defects, errors, and variations in processes, products, and services, leading to improved efficiency, quality, and customer satisfaction. Six Sigma emphasizes statistical analysis and measurement to identify and eliminate sources of variation.

Example

A manufacturing company implements Six Sigma principles to identify and minimize defects in its production process, resulting in higher-quality products, reduced waste, and improved customer satisfaction.
