This document discusses Lean Six Sigma as a methodology for continuous process improvement and cultural change. It combines Lean thinking about eliminating waste with Six Sigma's focus on reducing variation. The methodology aims to increase customer satisfaction through pursuing perfection, reducing costs and improving productivity. Key aspects include identifying and eliminating non-value-added activities, reducing defects and cycle times, and using statistical tools to measure, analyze and control processes. Both Lean and Six Sigma are needed to meet customer expectations, as their successful implementation enhances each other's performance.
