Impact of Real-Time MIS on Supply Chain Management  A Case Study Approach

Real-Time Management Information Systems (RT-MIS) are revolutionizing Supply Chain Management (SCM) by enhancing visibility and responsiveness. This study aims to evaluate the impact of RT-MIS on SCM performance, focusing on operational efficiency, lead time reduction, inventory management, and overall supply chain responsiveness. Conducted at the Department of Management Information Systems, Texas A&M University-Texarkana, from June 2023 to June 2024, this research employed a case study approach. Data were collected from five organizations across diverse industries that have implemented RT-MIS in their supply chains. Quantitative data were gathered through structured surveys and system performance metrics, while qualitative insights were obtained via in-depth interviews with supply chain managers and IT professionals. Statistical analyses, including descriptive statistics, regression models, standard deviation calculations, and hypothesis testing with p-values, were performed using SPSS version 26.0 to assess the relationship between RT-MIS adoption and key SCM performance indicators. The analysis revealed that RT-MIS implementation led to a 45% increase in operational efficiency (SD = 5.6) and a 38% reduction in lead times (SD = 4.9), both highly significant (p < 0.001). Inventory turnover improved by 30% (SD = 6.2, p < 0.01), and overall supply chain responsiveness enhanced by 35% (SD = 5.3, p < 0.001). Regression analysis indicated that RT-MIS adoption significantly predicts operational efficiency (R² = 0.67, p < 0.001) and lead time reduction (R² = 0.62, p < 0.001). Additionally, qualitative data highlighted enhanced decision-making capabilities and real-time problem-solving as critical factors contributing to these improvements. The standard deviations demonstrate consistent performance gains across different sectors, underscoring the versatility and effectiveness of RT-MIS in diverse supply chain environments. The integration of RT-MIS significantly enhances SCM performance, driving operational efficiency, reducing lead times, and improving inventory management. These findings underscore the strategic importance of real-time information systems in optimizing supply chain operations and fostering competitive advantage.
