Answer:
Forecasted sales
Step-by-step explanation:
In the production process amount of inventory purchased for producing goods must be carefully calculated.
This avoids waste incurred from buying excess of materials needed for operation. Also when there is shortage of materials time and resources are wasted getting more materials.
So when calculating material requirements for finished products it is important that we consider sales forecasts.
Materials purchased based on this will just adequately meet the demand for product.
This reduce cost of storage of excess materials.
