Implementation of business process re-engineering using lean and green strategy in manufacturing industry

This study includes a methodology for implementing the combination of lean, green and social assessment of a manufacturing cell in a six-sigma (DMAIC) framework. The effectiveness of this proposed methodology will be examined by a case study. This study shows an outline of the steps that need to be taken to have a complete sustainability assessment by using lean, green and six sigma techniques and practices. By combining lean and green strategies, all aspects of waste will be considered. Even though by the stow strategies helps in eliminating waste and improving environmental impacts, there is no consideration in the variability in the process. Six Sigma approach helps in reducing the variability of the production process. Each manufacturing systems has their own inputs, processes and outputs and has their specific problems that have to be studied by case-by case bases. On the other hand, considering employee and workers opinion about the productivity and quality plays an important role in optimization. Hence, in this study all aspect of sustainability is considered. Applying this methodology will improve economic, environment and social aspects of manufacturing cells.
