History and Goalīoth contemporary Lean and Six Sigma methodologies were developed in complex manufacturing settings. This means that Lean practitioners prioritize process optimization to create value, whereas Six Sigma advocates strive to eliminate defects and waste by reducing variability. Waste in Six Sigma is caused by variation within a process. One key conceptual distinction between the Lean and Six Sigma methods is how practitioners of these methods identify waste: Waste is defined in Lean as any process or activity that adds no value to the customer.
