Lean Six Sigma (LSS) has been implemented worldwide for many years and has been successful in many organizations. Liker and Rother (2011) pointed out that only 2% of companies successfully achieved the desired results with Lean plans. This book identified the critical success factors of LSS implementation for Chinese manufacturing companies and explored the challenges occurring during the LSS transformation. This book describes how the employee training process for LSS can be designed using total quality management (TQM) adoption in private manufacturing organizations in China and how LSS practices can be adopted successfully in SMEs in China. The author also examined and explored the critical success factors (CSF) of LSS implementation and discussed the challenges occurring during LSS transformation.
