Answer: D. It increases the need for suppliers to deliver raw materials on time.
Explanation:
The just-in-time costing system is employed in the just-in-time management strategy that aims to minimize inventory, increase efficiency while decreasing waste by receiving goods only as needed for production. The just-in-time production process depends on steady production, high-quality workmanship, no event of machine breakdowns, reliable suppliers etc. As it aligns raw-material orders from suppliers directly with production schedules, it therefore increases the need for suppliers to deliver raw materials on time for production of orders.
