Final answer:
JIT manufacturing emphasizes continuous improvement by minimizing inventory and improving quality control through timely delivery of parts.
Step-by-step explanation:
Of the options provided regarding just-in-time (JIT) manufacturing, the correct statement is that it emphasizes continuous improvement. This approach is characterized by minimizing inventory levels, having parts delivered exactly when they are needed, and improving quality control. JIT manufacturing requires suppliers to be located within a day's drive of the assembly plant to ensure timely delivery of parts, thus reducing waste and inefficiencies within the supply chain. Additionally, the reduction of inventory costs and enhanced quality control can potentially lead to a leaner, more efficient and competitive operation.
