Differences between Lean and Six Sigma


Six Sigma 

In Lean, waste is a process or activity that fails to add value to the customer. 

Lean professions focus on enhancing processes to create high customer value. 

In Six Sigma, waste is an output of a variation within a process. 

Six Sigma aims to remove waste by decreasing variability. 

Lean is a set of principles that enables a business to make smarter decisions. 

Six Sigma is a structured approach to identify and eliminate problems in an organization. 

Lean’s leadership principles are fluid. They allow everyone, from individual contributors to prominent executives, to come together in solving organizational problems. 

Six Sigma has a more structured leadership model suitable for large organizations where hierarchy is there. 

Although there are differences between Lean and Six Sigma, their end goal is to make processes more efficient by eliminating waste.
