Lean transformation in electricity transmission tower manufacturing company-a case study

Abstract

After the post-second world war, Toyota company have not only proposed but also implemented lean philosophy and became very successful. Their success story has motivated different companies the world over and they started implementing lean philosophy. In this journey of lean transformation, not many companies have achieved success. Many organizations could not achieve success as they failed in managing challenges that they faced during lean transformation. Few successful companies even have not reaped the full potential of lean philosophy. This is true even in the case of electricity tower manufacturing. As for the knowledge of the author goes, not many companies have achieved success in electricity tower manufacturing companies. In this context, the current research assumes special significance. The current research work does a comprehensive study of electricity tower-making plants and applies value stream mapping tools and creates a current state map. Also, tries to identify different types of wastes and propose a future state value stream map. Current work also presents lean implementation. In the end conclusions from the current research work are presented. Conclusions have shown how productivity has improved in electricity transmission tower manufacturing company. Thus, the research findings are useful for academicians and practitioners.
