In the contemporary business environment, Big Data Analytics (BDA) has emerged as a pivotal tool for enhancing strategic and operational decision-making. This research paper investigates the applications of Big Data Analytics across five globally recognized companies—Amazon, Netflix, Walmart, Starbucks, and UPS—to understand how data-driven insights support managerial decisions. The study adopts an empirical case study approach, using secondary data sources including annual reports, industry analyses, and prior research studies. Findings reveal that Big Data Analytics plays a critical role in improving customer engagement, operational efficiency, inventory management, predictive maintenance, and profitability. The paper concludes that organizations integrating data analytics into their core decision-making processes achieve superior performance, agility, and competitive advantage. The study also highlights implications for management practitioners and suggests future research directions in the field of data-driven business management.
