Week 9

Question 1

Describe JIT production.

Answer 1

JIT is a “demand-pull” system where each production component is produced only when needed by the next step, minimizing excess inventory.

Question 2

What is the primary goal of Just-in-Time (JIT) production?

Answer 2

To streamline the production process by eliminating non-value-added activities, meeting customer demands in a timely way, ensuring high-quality products, and minimizing costs.

Question 3

How does JIT differ from materials requirements planning (MRP)?

Answer 3

JIT is a demand-pull system focused on producing items only when needed, while MRP is a push-through system that produces goods based on forecasted demand.

Question 4

What is JIT purchasing?

Answer 4

JIT purchasing is acquiring materials just in time for production, reducing inventory carrying costs and relying on electronic links to place orders.

Question 5

Name some key features of a JIT production system.

Answer 5

Features include high-quality standards, cross-trained employees, manufacturing cells, reduced setup times, and a focus on eliminating defects.

Question 6

List advantages of JIT production.

Answer 6

Lower inventory costs, improved cash flow, reduced obsolescence, increased customization, better quality, and stronger supply chain collaboration.

Question 7

What are some disadvantages of JIT production?

Answer 7

Disadvantages include dependency on suppliers, vulnerability to demand surges, higher administration costs, potential for stock-outs, and increased training and technology costs.

Question 8

Why is supplier reliability critical in a JIT system?

Answer 8

JIT relies on timely, high-quality supplies; any delay or quality issue from suppliers can disrupt the production process, leading to costly delays.
