Six Sigma is a process based or project-based approach for improving the quality of the products and services. It enables businesses to provide products or services which are reliable and consistent. The concept behind this approach is to reduce the variation in processes. Six Sigma is a customer focused continuous improvement strategy that minimizes defects and variation in product design, production or administrative process.

A six sigma process produces less than 3.4 defectives per million opportunities. The central idea behind Six Sigma is to eliminate the defects and get as close to "zero defects" as possible.

Lean is a methodology for identifying and eliminating waste in the process and helps in improving productivity, reducing cycle time, lead time and inventory. Implementing both these methodologies as Lean Six Sigma in any organization helps in improving productivity and quality and results in substantial improvement in customer satisfaction and cost savings.
