The aim of the present research work is to conduct productivity assessment studies, to improve operational efficiency, and provide recommendations for productivity improvement for a solar module manufacturing plant. An effort is made in this work to construct a current state value stream map for capturing the existing data for subsequent analysis of a solar panel manufacturing plant. After a thorough analysis, the future state value stream map is developed. The recommendations derived from the future value stream help the organization implement corrective solutions to existing bottlenecks in order to enhance customer satisfaction. Also, the requirement for incorporating the lean tools in organizations leads to better productivity as well as provides insights on potential constraints.
