Enterprise resource planning (ERP) software evolved from early manufacturing scheduling systems to integrate core business functions like finance, procurement, and supply chain operations into a single system. ERP 1.0 focused on integrating departments, ERP 2.0 improved usability, and ERP 3.0 adds predictive analytics and personal assistants. ERP streamlines supply chain management by enabling efficient demand planning, procurement, inventory management, and customer service across the integrated system.
