What are the main features of JIT production, and what are its benefits and costs?

Short Answer

Expert verified
The main features of JIT production include a pull-based system, reduced inventory levels, continuous improvement, strong supplier relationships, and increased flexibility. Benefits of JIT production are reduced inventory costs, improved cash flow, enhanced product quality, reduced production lead times, and increased efficiency. However, there are costs and drawbacks such as higher risk of stock-outs, supplier dependency, complexity in production planning, and the need for employee training.

Step 1: Introduction to JIT (Just-In-Time) Production

JIT production is a manufacturing strategy that incorporates lean principles and aims to increase efficiency by producing products only when they are needed, reducing inventory levels and manufacturing costs. By focusing on reducing waste in the supply chain, JIT production can result in several benefits but can also have some drawbacks.

Step 2: JIT Production - Main Features

There are several main features of JIT production, including: 1. Pull-based System: JIT production operates using a pull-based system, where products are not made until an actual customer demand signals production. 2. Reduced Inventory Levels: JIT production aims to minimize inventory throughout the supply chain, reducing the amount of raw materials and finished goods on hand. 3. Continuous Improvement: JIT production encourages continuous improvement through ongoing efforts to reduce waste and improve manufacturing efficiency. 4. Supplier Relationship: JIT production depends on strong supplier relationships to ensure timely delivery of materials. This includes working closely with suppliers and sharing information to create a more efficient supply chain. 5. Flexibility: JIT production allows for greater flexibility in manufacturing operations by focusing on producing small batches of products and quickly adapting to changes in customer demand.

Step 3: JIT Production - Benefits

The benefits of the JIT production system include: 1. Reduced Inventory Costs: By maintaining lower inventory levels, companies can experience cost savings in storage and carrying costs. 2. Improved Cash Flow: Reducing inventory levels can improve cash flow, as less capital is tied up in raw materials and finished goods. 3. Enhanced Quality: With a focus on continuous improvement, JIT production systems often lead to higher-quality products due to a close inspection of each production step. 4. Reduced Production Lead Time: JIT production systems aim to shorten the time between receiving an order and delivering the finished product, resulting in quicker order fulfilment and increased customer satisfaction. 5. Increased Efficiency: By focusing on eliminating waste and redundancies in the supply chain, JIT production can lead to increased efficiency in manufacturing operations.

Step 4: JIT Production - Costs

Although there are many benefits to JIT production, there are also some costs and potential drawbacks, such as: 1. Higher Risk of Stock-outs: Since inventory levels are minimized in JIT production, there is an increased risk of stock-outs due to unforeseen shifts in customer demand or supplier disruptions. 2. Supplier Dependency: JIT production relies heavily on timely and consistent delivery of materials from suppliers, which can lead to a higher dependency on these relationships and increased vulnerability to supply chain disruptions. 3. Complexity in Production Planning: JIT production requires more sophisticated production planning systems and processes to manage the complex demands of minimizing inventory while still responding quickly to fluctuating customer demand. 4. Employee Training: Implementing a JIT production system often involves significant employee training to ensure everyone is familiar with the new processes and procedures. By understanding the main features, benefits, and costs of JIT production, businesses can make informed decisions about whether implementing this manufacturing strategy is the right choice for their operations.

What is supply-chain analysis, and how can it benefit manufacturers and retailers?

Chapter 20

E00 for a retailer. The Fabric World sells fabrics to a wide range of industrial and consumer users. One of the products it carries is denim cloth, used in the manufacture of jeans and carrying bags. The supplier for the denim cloth pays all incoming freight. No incoming inspection of the denim is necessary because the supplier has a track record of delivering high-quality merchandise. The purchasing officer of the Fabric World has collected the following information: The purchasing lead time is 2 weeks. The Fabric World is open 220 days a year 144 weeks for 5 days a week. 1\. Calculate the EOQ for denim cloth. 2\. Calculate the number of orders that will be placed each year. 3\. Calculate the reorder point for denim cloth.

Chapter 20

Jill's Custom Bags manufacturers and sells 12,000 customer designer bags per year, each requiring three yards of a specially manufactured fabric. These bags are sold evenly throughout the year. The materials for these bags require two months' lead time. Jill desires to maintain a safety stock of sufficient material to meet one month's demand. What is Jill's reorder point? a. 3,000 b. 6,000 c. 9,000 d. 12,000

Chapter 20

Why do better decisions regarding the purchasing and managing of goods for sale frequently cause dramatic percentage increases in net income?

Chapter 20

Backflush, two trigger points, completion of production and sale (continuation of \(20-37\) ). Assume the same facts for Acton Corporation as in Problem \(20-37\), except that now assume Acton uses a JIT production system and backflush costing with two trigger points for making entries in the accounting system: Completion of good finished units of product Sale of finished goods The inventory account is confined solely to finished goods. Any under- or overallocated conversion costs are written off monthly to cost of Goods Sold. 1\. Prepare summary journal entries for August, including the disposition of under- or overallocated conversion costs. Acton has no direct materials variances. 2\. Post the entries in requirement 1 to \(T\) -accounts for Finished Goods Control, Conversion costs Control, Conversion costs Allocated, and cost of Goods Sold.
