Materials Requirements Planning (MRP) is a business process that helps manage an organization’s materials and inventory requirements. It does this by ensuring that the right materials are available when they’re needed, in the right amounts and at the right times. MRP actively tracks material supplies and inventory levels, so that businesses can manage their resources more efficiently. By making sure that the right materials and inventory levels are maintained, MRP helps to decrease production costs and increase profits. In short, Materials Requirements Planning provides businesses with a powerful tool for managing their supply chain.
