Traditional supply chain management has historically been plagued by challenges such as delays, inefficiencies, and a lack of transparency due to its reliance on forecasts and estimates. However, the introduction of real-time transportation visibility (RTTV) marks a significant evolution, enabling supply chains to become more responsive, efficient, and customer-centric by allowing businesses to track and monitor goods in transit instantaneously. The development of RTTV, facilitated by technologies such as IoT, GPS, cloud-based platforms, predictive analytics, and machine learning, offers enhanced shipment visibility, data-driven decision-making, increased operational efficiency, and improved customer satisfaction. These advancements allow companies to optimize routes, manage inventory more precisely, and provide real-time updates to customers, thereby transforming supply chain management into a more agile and transparent system. As global supply chains continue to evolve, companies like PubNub play a crucial role in integrating real-time functionality into visibility solutions, helping businesses navigate modern supply chain challenges effectively.
