The bullwhip effect remains a pervasive challenge in supply chain management, causing inefficiencies, increased costs, and disruptions. This research delves into the role of Retailer Enterprise Marketing Information Systems (REMIS) in mitigating the bullwhip effect. By examining the impact of REMIS on supply chain dynamics, we explore how data-driven insights, forecasting accuracy, and demand coordination can be harnessed to minimize supply chain oscillations. Through a combination of empirical analysis and case studies, this study sheds light on the effectiveness of REMIS as a strategic tool in bridging the supply chain gap and fostering smoother operations. The findings provide valuable insights for retailers, manufacturers, and supply chain practitioners seeking to optimize their operations and minimize the bullwhip effect.
