So from that the company needs to implement planning regarding inventory control which estimates the accuracy between inputs into output and the accuracy of the quantity or volume of raw materials. In the real world there are many companies that have not noticed the importance of managing raw material inventories, this can be found in companies that experience excess raw materials in warehouses, as well as running out of raw materials. Monitoring inventory that is well implemented can trigger the success of a company in the production sector in a timely manner.
