Which of the following is a key principle in Just-in-time manufacturing?

Just-in-time (JIT) manufacturing is fundamentally about minimizing waste, which includes reducing excess inventory. The key principle revolves around producing and delivering products as they are needed in the production process, rather than stockpiling large amounts of inventory. By maintaining only the essential inventory, JIT aims to ensure that resources are used effectively and efficiently, leading to lower holding costs and reduced waste. This approach enhances the overall responsiveness of the manufacturing process and allows for more flexibility to adapt to changing customer demands.

Maintaining a focus on essentials also encourages continuous improvement in processes and helps in pinpointing any inefficiencies. This principle directly contrasts with the ideas of producing large quantities in advance or stocking up on supplies, which can lead to unnecessary expenses and resource wastage. Additionally, while production efficiency is important, JIT emphasizes the balance between efficiency, inventory management, and meeting customer demands rather than solely concentrating on production metrics.
