What distinguishes Six Sigma from Lean Six Sigma?

Lean Six Sigma is a distinct process from regular Six Sigma, with a focus on eliminating waste and reducing variation in a production setting. The eight types of waste include defects, over-production, waiting, underutilization of talent, excess transportation, excess inventory, excessive motion, and unnecessary processing. It‘s important to note that Lean Six Sigma is not about cutting corners to save money, but rather about adding value to a product. As long as the return on investment is favorable, Lean Six Sigma is in support of it.
