Global competition, a phenomenal, increased rapidly in over three decades, compelling manufacturing companies to escalate production rate, augment product quality, increase  manufacturing process, minimize lead time, reduce cost, decrease work-in-progress materials, by means of strategically systematic and dynamic approach to enable catch up World standard. In carrying out these, companies often land up in imbalance in resource allocations and inventory management. There by bringing an indecisive situation. The system dynamics is a management science technique with its potential in accommodating future variation and in assessing the desired quantum and flows of different elements of the system in a dynamic way leading  to appropriate decision, in determining dynamics of behavior pattern of interactive variables in a system and there from understanding the reasons for such variations and triggering to identification of corresponding regulating variables as controlling and regulating measures to adopt better control and thereby achieving desired strategic goals.  This paper describes how system dynamics helps in achieving excellence in a manufacturing system strategically.
