Lean Six Sigma is a process improvement program that combines two ideas: Lean as a collection of techniques for improving flow in the value stream, eliminating waste and reducing the time needed to provide products or services, and Six Sigma is a collection of techniques and methodology for uncovering root causes to understand and reduce variation, consequently improving the quality of products and services, substantially contributing to increased customer satisfaction.
By combining the two methodologies, Lean Six Sigma is a proven business management strategy that helps organisations operate more effectively and efficiently by reducing variation and waste.
