View Answer

Answer: D

Explanation:

Just-in-time (JIT) manufacturing is a production strategy that produces goods based on customer orders and reduces inventory levels by ordering materials only as they are needed for production1. This minimizes the waste of overproduction and inventory, which are the most common and costly forms of waste in manufacturing2. By eliminating excess inventory, JIT manufacturing also reduces the waste of waiting, movement, defects, and overprocessing that are associated with inventory management3.
