In today’s world, business has become more competitive. All industries and organizations have to perform well in order to survive and be profitable.
The lean six sigma (LSS) methodology is being applied extensively to tackle many qualities related issues in many processes of today’s industries. Various companies have benefited greatly from the adoption of six sigma and lean engineering concepts since their initiation.
  A paper cement bags is a packaging sack made of paper high quality and usually craft virgin fiber, which usually consists of several layers to provide strength, with high elasticity and high tear resistance, and are designed for packaging products with high demands for strength and durability.
This study is interested in implementing the lean six sigma (LSS) methodology in SMEs. The LSS proposed in this study is not only study LSS framework but also focus of LSS implementation in SMEs. The contribution of this research is using LSS methodologies to reduce waste of time, reduce of defects, and increase the level of sigma. 
The obtained results after implementation LSS methodology in the application of the  cement bags industry indicate that the production rate could be increased about 4.25 % and also could be in save of around $ 8,952 from a reduction of waste time and $ 12,730.61 from defects reduction; the total is $ 21,682.61 per year. In addition, the preparation time could be reduced by about 4.57 %, increase the OEE by 20%, and increase the level of sigma from 3.91 to become 4.00.
