Which technology is commonly used to track shipments in distribution management?

The Global Positioning System (GPS) is commonly used to track shipments in distribution management due to its ability to provide real-time location data. This technology relies on satellite signals to determine the precise location of vehicles and goods as they move throughout the supply chain. By leveraging GPS, companies can monitor shipments continuously, enhance route planning, and improve delivery times by providing visibility to both logistics managers and customers.

The use of GPS significantly streamlines the distribution process, allowing businesses to respond quickly to any delays or issues during transit. This visibility not only enhances operational efficiency but also boosts customer satisfaction, as clients can often track their shipments in real time.

In contrast, other options like ATMs, social media, and CRM are not specifically designed for tracking shipments. ATMs are focused on financial transactions, social media is primarily for communication and marketing, and CRM systems are intended for managing customer interactions and data. These technologies lack the specific functionalities needed for effective shipment tracking, making GPS the most appropriate choice in the context of distribution management.
