Lean Six Sigma is a method for improving performance by systematically removing waste and reducing variation that relies on a collaborative team effort. Increased performance and decreased process variation contribute to defect reduction and improvements in profits, employee morale, and product or service quality.
The Lean Six Sigma Belts indicate different stages of knowledge, skill and experience in a process improvement practitioner's development. These clearly defined roles help structure an organization’s continuous improvement strategy, as every belt level plays a key part in the success of Lean Six Sigma initiatives.
