What Is MRP and How Does It Work?

Material Requirements Planning (MRP) is a computer-based system used in manufacturing to ensure that the right materials are available at the right time to meet production schedules.

MRP operates as part of the broader Sales and Operations Planning (S&OP) process, taking inputs such as:

  • Demand Data: Customer orders, forecasts, or aggregate demand plans

  • Bill of Materials (BOM): Detailed lists of components for each product

  • Inventory Data: Current inventory levels and stock availability

  • Lead Times: Procurement and production time requirements

  • Order Quantities: Minimum, economic, or standard order sizes

MRP Generates Key Outputs:

  • Purchase Orders: To procure materials from suppliers

  • Production Orders: To trigger in-house manufacturing

  • Replenishment Orders: To maintain optimal inventory levels

  • Rescheduling Alerts: To adjust production plans for changes or disruptions

When implemented correctly, MRP improves synchronization across procurement, production, and inventory, resulting in higher efficiency and lower costs.
