In this research work is to develop a quality value stream mapping (Q-VSM) for a production in a heavy transformer manufacturing company in India. The process begins with creating a current state map (CSM) and understands the production flow and the current cycle times. This provides the current information needed to produce a future state map (FSM). The goal is to identify and eliminate the waste, and non-added materials which is any activity that does not add value to the final manufacturing product, in the production process of the company. To collect the information needed, the study was conducted within the manufacturing production facility to enable the researcher gained knowledge and familiarized with the production flow and the activities being performed at the shop floor of the company. Parameters such as working time, cycle times, brake down times, and work in process for inventory and manufacturing materials, and information flow paths were recorded. High performance computer based "ARENA" simulation software was used to simulate and analyze the process flow and working process times. Result from the analysis shows that there are areas where the company can further improve their Manufacturing Production System (MPS). The results show the improvement of the manufacturing efficiency up to 64% based on the new proposed arrangement of the layout. Therefore propose of shop floor layout will be guided to the company in order to improve their manufacturing production system.
