What is Six Sigma?

Six Sigma is a method that provides organizations with tools to improve their business processes. It is a data-driven philosophy of improvement that views work as processes which can be analyzed and optimized using both qualitative and quantitative tools. As a methodology, Six Sigma is focused on reducing process variation, which in turn increases process capability and leads to decreased defects, improved profits, quality of products or services, and employee morale.

At its core, Six Sigma is a problem-solving approach that uses statistical process control, control charts, failure mode and effects analysis, and process mapping, among other tools. It emphasizes defect prevention over defect detection and values work standardization and flow to reduce waste and enhance customer satisfaction. This methodology not only drives improvements in the bottom-line results but also promotes a long-term commitment to quality and efficiency within an organization.

Lean Six Sigma combines the principles of Six Sigma with Lean practices, aiming to reduce variation, waste, and cycle time. It is a philosophy that involves every employee and applies wherever variation and waste exist, requiring a supportive management environment, training in statistical thinking, and project management skills. The implementation of Six Sigma necessitates a closed feedback loop to effectively monitor and sustain progress.
