First, MRP I does not lend to optimize materials acquisition costs. Because inventory levels are kept to a minimum, materials must be purchased more frequently and in smaller quantities. This results in increased ordering costs. 3) While MRP I is still being used by many firms, it has been updated and expanded to include financial, marketing, and logistics elements. This newer version is called manufacturing resource planning, or MRP II.
