Lean Six Sigma: an integrated strategy for manufacturing sustainability

Both Lean and Six Sigma are key business process strategies which are employed by companies to enhance their manufacturing performance. However, whilst there is significant information available on implementing Lean Six Sigma in companies, these business improvement strategies are still implemented primarily in a sequential manner and the results of the survey included in this paper identify the fact that little information exists regarding the integration of these approaches to provide a single and highly effective strategy for change in companies. This paper introduces an integrated approach to Lean Six Sigma and proposes a Lean Six Sigma strategy for industry as a result of the information collected from a survey of 100 manufacturing companies which apply Business Process Improvement (BPI) initiatives (Lean, Six Sigma or Lean Six Sigma). The rationale is that the effective implementation of Lean Six Sigma will lead to greater opportunities for companies to achieve economic sustainability through continued growth and improved manufacturing efficiency.
