Nowadays in a competitive market, various industries are facing various problems because of changing scenario in terms of high-quality demand, reduced the cost of production and increased productivity. This thesis attempts to provide a successful solution for these problems through lean manufacturing techniques. Lean manufacturing is the best technique for the elimination of waste from the organization. Value Stream Mapping (VSM) is one of the lean manufacturing tools. In VSM processes in an organization are strictly divided into the two groups: Value Adding Processes (VA) and Non Value Adding Processes (NVA). The goal of VSM is to identify waste in terms of nonvalue-added processes. Current State Map (CSM) is drawn to give details about the current position and find various problem areas. Future State Map (FSM) is drawn to show the implementation action plan. In this thesis, a study has been carried out from Maheshwari Power Drive, G.I.D.C., Naroda, Ahmedabad. Three product line of different pulley like 36 8M 45 timing pulley, 22 8M 25 timing pulley, 32 8M 50 timing pulley are analyzed. In this study, first of all, collecting the details from each product line and create a three current state map and then choose any one as per requirement of the improvement. Then create a future state map for the plan of improvement and then apply the proposal within the industry.
