What is the difference between Lean and Lean Six Sigma?

Lean and Six Sigma, two popular process improvement methods, work together as Lean Six Sigma to help people and organizations achieve their goals of making customers happy, engaging workforces, reducing errors and costs, and much more.

The main difference between Lean and Six Sigma is that Lean primarily focuses on streamlining and reducing waste within a process—making it faster and more efficient. Six Sigma focuses on reducing the number of defects in the product or service produced by a process—increasing the quality of the process.
