A Manufacturing Resource Planning (MRP) System is an automated and integrated system used by manufacturers to plan and manage their operations. It helps companies maximize efficiency, reduce costs, and avoid inventory shortages by accurately tracking the materials, components, and parts required for each product they make. MRP systems are designed to improve efficiency and accuracy by providing real-time updates on available inventory levels, production status, and other data points that can help identify potential production problems before they occur. By keeping track of past, current, and future assembly requirements, a well-implemented MRP system can provide invaluable insights into how best to optimize resources and achieve a competitive edge in the marketplace.
