Final answer:
The major difference between the JIT and traditional approaches to manufacturing is that the JIT approach operates with low inventory levels while traditional approaches may operate with high inventory levels.
Step-by-step explanation:
The major difference between the just-in-time (JIT) and traditional approaches to manufacturing is that the JIT approach operates with low inventory levels while traditional approaches may operate with high inventory levels. In the JIT approach, inventory is acquired and used as soon as needed in the production process, reducing the need for storing excess inventory. This allows for more efficient production and cost savings.
