What is Material requirements planning? (MRP1)

• A. A computerised system that incorporates a single database used by many different areas of the organisation. Enables optimal inventory control based on matching of supply and demand
• B. A method to forecast demand for finished goods
• C. Calculate the quantity of materials required for each type of material and when they will be required
• D. A method of benchmarking against the best in the industry

Answer: (C)

Material requirements planning is a technique for planning what materials are needed and when, to support a production schedule. It uses the master production schedule (what must be produced and when), the bill of materials (what components and quantities are required for each finished item), and current inventory levels to work out exact material quantities and timing. By converting the production plan into planned orders for purchases or manufacturing, it ensures materials arrive when needed, helping to prevent stockouts and reduce excess inventory.

This approach is specifically about determining how much of each material is required and the timing of those needs. It differs from simply forecasting finished goods, which predicts demand for final products rather than detailing the materials and timing to support production. It also isn’t about benchmarking against others or describing an ERP system in general terms; it’s the targeted calculation of material quantities and when they are needed to meet the production plan.
