Reliance Fresh uses a knowledge management system to share information between its head office, stores, employees, customers, and vendors. Store employees identify requirements and communicate purchase requests to the head office through SAP. The head office identifies vendors, raises purchase orders, and sends them to vendors and stores. Vendors fulfill orders and send goods to stores. Stores update their inventory and check goods received against purchase orders. The document also describes processes for waste management, sales target management, and communication between stores and the head office.
