A model of Lean-Sigma to enhance a manufacturing system through integrating Lean Manufacturing and Six Sigma approaches

Six Sigma aims at reducing defects by reducing variability in the system which is its primary concentration; while Lean Manufacturing aims at reduce/eliminate waste where reducing defects through variability could be one or more of its concentration. While many organizations are using either Six Sigma and/or Lean Manufacturing independently there is no real research to use them in unison as Lean Sigma instead of using them as two independent bodies for continuous Improvement. This Thesis attempts to integrate Six Sigma and Lean Manufacturing to propose a model for Lean Sigma which will allow using the tools of Six Sigma and Lean Manufacturing to reduce/eliminate waste by working in unison rather than independently.
