The aim of the current study is to improve the performance of corporate through application of System Dynamics (SD) methodology. The paper discusses the importance of system dynamics modelling in enhancing corporate performance and how it shows the dynamic behaviour of the system. For this purpose a system dynamics model for an Indian Steel company has been prepared. The paper also covers a brief introduction of the system dynamics modelling, a brief narration of Steel Sector and the process adopted in modelling. Some of the important corporate performance parameters such as market share, revenue, employee's strength, number of shareholders, installed capacity have been taken to reflect corporate behaviour. The behaviour of these performance parameters over time is used for both validation of the model as well as for reflecting their future pattern. The paper concludes that the SD modelling approach has high potential in understanding corporate performance behaviour and their by gaining insight into the corporate functioning and taking appropriate remedial steps for improving its performance.
