Ashok Leyland implemented several strategic revamping measures to improve its inbound supply chain and reduce costs. It launched Project OSCARS to optimize the supply chain and rationalize sourcing. This included implementing a single window system for vendors, tiering suppliers, and a just-in-time system. Ashok Leyland also re-engineered its outbound supply chain to improve customer satisfaction and reduce finished goods inventories by focusing on order to delivery times, delivery reliability, and providing order status updates. The supply chain revamping led to quantitative benefits like reduced raw material costs by 1-2%, lowered inventories by Rs. 300 crore, and increased profits and sales volumes.
