Final answer:
In a Just-In-Time (JIT) system, quality production facilities, methods, employees, and the acquisition of quality raw materials are required, as well as reliable suppliers that can possibly be under long-term contracts. Therefore, all the statements I, II, and III regarding quality are true for a company that has implemented a JIT system.
Step-by-step explanation:
The question pertains to the characteristics of a Just-In-Time (JIT) system in a manufacturing setting. Under a JIT system, the requirements are multifaceted and not limited to just quality raw materials or long-term supplier contracts. Let's explore the statements provided:
- JIT requires quality production facilities, methods, and employees: This is true because JIT relies on the timely production of high-quality products to meet immediate demands without excess inventory.
- JIT requires the acquisition of quality raw materials: This statement is also correct. Since JIT systems have minimal inventory, any defects or issues with raw materials would directly impact the production line and potentially halt operations.
- JIT requires that long-term contracts be negotiated with quality suppliers: While long-term contracts can be part of a JIT system, they are not a requirement. Suppliers must be reliable and capable of meeting the demands of JIT, but the length of contracts can be variable depending on the situation.
So, the correct answer to the question, which statements regarding quality are true for a company that has implemented a JIT system, is I, II, and III.
