Maruti Suzuki implemented an ERP system using Oracle software to integrate its various business processes and systems. Previously, Maruti Suzuki had disparate legacy systems that lacked integration and real-time access to information. The ERP implementation was done in phases, starting with finance and moving to procurement and HR. It provided benefits like standardized processes, inventory management, cost reductions, and improved forecasting and compliance. Change management and training helped ensure a smooth transition. The ERP system gave Maruti Suzuki improved visibility, control, and insights across its business units.
