MRP1 is described as which of the following?

• 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 focuses on working out the quantities of each material needed and the timing of their availability to support the master production schedule. It uses the bill of materials, the production schedule, and current stock levels to calculate net requirements and generate orders so materials arrive just in time for production. This makes it the best description because MRP1 is about planning material quantities and when they are required, translating the production plan into actionable procurement and manufacturing actions. The other descriptions describe demand forecasting for finished goods, benchmarking, or broader system features rather than the specific purpose of planning material requirements.
