  15. 15. 5/12/2015 Dept of ISE 15 Conclusions Companies that deploy lean manufacturing, Six Sigma and LSS models achieve superior performance in competitive priorities like quality, reliability and speed. Application of LSS makes it possible to reach a wider range of competitive priorities compared to the isolated application of the models. In addition to cost reduction, the models allow the organizations to be faster, have superior quality, to offer greater reliability in products and services and flexibility to serve customers.
