JIT manufacturing embodies a demand-pull system instead of the traditional “push” system. Every manufacturing operation produces only what is required to satisfy the demand of the following processes. Details and raw materials arrive in the manufacturing plant on time and are effectively used in production. Toyota’s case study was backed by examples from Japanese shipyards, which used JIT to reduce inventory levels. Other companies saw how Toyota and Japanese shipyards, partially due to JIT manufacturing, survived the oil crisis. Toyota and shipyards both managed to figure out a way to engage with every employee during the crisis and streamline their manufacturing processes for maximum output.
- The just-in-time (JIT) inventory system is a management strategy that aligns raw-material orders from suppliers directly with production schedules.
- If you’re looking to implement a JIT manufacturing process, follow these steps.
- This strategy is used to minimize inventory and increase efficiency within a company’s supply chain.
- But it will also require a bigger storage space and will run the risk of pilferage, theft, obsolescence or spoilage.
- Just in Time production is a manufacturing strategy designed to increase efficiency and reduce waste by producing goods only as needed.
It can reduce the amount of capital required to get the business up and running. Obviously, using this sort of inventory method works only if a company has an efficient inventory management system and reliable suppliers. The main philosophy behind JIT is to eliminate waste, whether stock, inventory or time.
Depending on the industry that your manufacturing business is in, you can adopt one from any of the different types of inventory management. “If you’re successful, you can expect improved cash flow and happier customers,” Gordon said. When pulled off, JIT can work for small and large manufacturers, as myriad examples reveal. Harley Davidson is one such example, shrinking inventory levels by 75% while simultaneously raising productivity. While controversial from a union perspective, the main factory in York, Pennsylvania, also cut the workforce from about 2,700 to 1,600 during its ’80s push to lean out. Monitoring how well an organization responds when it doesn’t meet JIT and customer expectations is a helpful KPI, as well.
While low inventory can be beneficial to a company’s bottom line in a number of ways, running a business this way requires a great deal of coordination. From obtaining the raw materials needed for manufacturing to ensuring timely delivery, every aspect of JIT production must be synchronized. This often means businesses must invest in the implementation of information technology to enable automatic notification to suppliers when orders are received. Just-in-time https://1investing.in/ manufacturing (JIT), Production-control system, developed by Toyota Motor Corp. and imported to the West, that has revolutionized manufacturing methods in some industries. By relying on daily deliveries of most supplies, it eliminates waste due to overproduction and lowers warehousing costs. Supplies are closely monitored and quickly altered to meet changing demands, and small and accurate resupply deliveries must be made just as they are needed.
You’ll have fewer products on hand and reduce the risk of purchasing products you can’t sell. With JIT, you don’t have to worry about unwanted inventory in the event an order gets canceled or is not fulfilled for any other reason. This allows them to keep optimal levels of stock and eliminate excess inventory that would lead to waste. As we’ve already talked about manufacturing, let’s take a JIT example from the food business instead. Instead of ordering a large number of ingredients every week and freezing them for preservation, a restaurant with a JIT approach will order a reduced amount of food every day.
Famous for its JIT inventory system, Toyota Motor Corporation orders parts only when it receives new car orders. Although the company installed this method in the 1970s, it took 20 years to perfect it. This is where material resource planning software or enterprise resource planning (ERP) software comes to play.

How Does Just-in-Time Inventory Work?
If your business depends on inventory to build your brand and generate revenue, just-in-time (JIT) inventory should be on your radar. It’s a buzzword in the supply chain world as well as a tried-and-true technique that can help you improve efficiency and increase your bottom line. There are many advantages to working in smaller lots, including better quality, reduced equipment inventory and reduced storage costs. In terms of JIT, smaller lots mean you’re only using what you need and nothing has to be stocked. Like kanban or lean manufacturing, JIT also focuses on continuous improvement and eliminating waste. Therefore, you need to put production control systems in place to capture these problems so you can resolve them quickly.
Examples of the Just-In-Time (JIT) Inventory Process
Their production and warehousing were small, housing only minimum levels of inventory. This method was later developed further and was brought to fame by Toyota Motors in the 1970’s. A low inventory figure on the balance sheet means a higher inventory turnover ratio, making the company look more efficient. The inventory turnover ratio is a metric used in corporate finance to estimate how efficiently a company is selling its products. He developed the pull system and kaizen techniques to implement the lean manufacturing concept.
Toyota Production System – a JIT principle
“Just in time” means that the success of this business strategy depends largely on precise coordination between businesses and their suppliers to ensure prompt delivery. Because there is no inventory buffer, business can suffer greatly if any one element of production is delayed. You can use Katana manufacturing software to streamline all your production processes and use live data for real-time planning. Katana ERP is a flexible solution for JIT manufacturers as you can integrate it with multiple accounting, e-commerce, reporting and CRM tools, while also benefiting from essential business tools like order management. Overproduction led to excess inventory, and created the need for more workers, equipment, floor space and activities to manage inventories. Defects or design changes were particularly problematic if there was a large inventory of parts on hand or in the pipeline, because it meant they had to be reworked or scrapped.
If a supplier increases their prices suddenly, you can become unraveled as you scramble to find a better deal as inventory levels dwindle. Toyota Production System is built on their principle of “Maximizing production efficiency by eliminating waste.” It is simply producing only what is needed, when it is needed. Toyota Motors’ adoption and further development of the JIT method made the automotive manufacturer as the benchmark when it comes to efficient production. The JIT method is now also known as the Toyota Production System or the lean manufacturing system that is being applied globally.
Just-In-Time Manufacturing & Production (JIT): A Quick Guide
In this way, less storage space is needed, less food is wasted and the freshness of the dishes (quality) increases. While larger companies have a competitive edge over smaller ones in terms of working out beneficial relationships with suppliers, a strong supplier relationship is crucial for JIT to work. Any disruption in the supply chain can be harmful to just-in-time manufacturing. Develop good relationships with your suppliers, build trust and, if possible, choose to work with suppliers that are physically close to your facility. For just-in-time manufacturing to work, manufacturers must have a suitable product or service, a specific quantity and an agreed-upon timeframe.
A just-in-time (JIT) inventory system is a management strategy that has a company receive goods as close as possible to when they are actually needed. So, if a car assembly plant needs to install airbags, it does not keep a stock of airbags on its shelves but receives them as those cars come onto the assembly line. The JIT inventory system contrasts with just-in-case strategies, where producers hold sufficient inventories to have enough products to absorb maximum market demand. For JIT manufacturing to succeed, companies must have steady production, high-quality workmanship, glitch-free plant machinery, and reliable suppliers.
Backward scheduling involves starting with the customer’s due date and working backward through the production process. The organization plans and schedules production to minimize delays and stockouts and ensures everything is in place when needed. Ohno observed that traditional mass-production methods resulted in large amounts of waste, including excess inventory, overproduction, and defects. He believed that by eliminating these types of waste, companies could significantly improve their efficiency and profitability. It’s unknown exactly when Japanese manufacturers began adopting JIT manufacturing practices, but it is certain that they were triggered by the economic climate of the post-World War II era. Following the war, Japan lacked the cash to finance big-batch, large inventory production methods used by other developed countries.
If you’re interested in using JIT to improve the way you operate, JIT inventory management software is worth considering. It can automate your processes and make it easier what companies use jit manufacturing to take advantage of this strategy. While there are many JIT software options on the market, some of the best include Netsuite ERP, ShipBob, Zoho Inventory and Sortly.
Increased efficiency helps companies to match supply with demand, improving their production processes. Just in Time production also reduces lead times, increasing customer satisfaction. Just-in-time manufacturing is a production planning system that aligns material orders with production schedules so raw materials only arrive as they are needed for the manufacturing process. This produces less waste, controls production inventory levels and reduces inventory costs, as you only use what’s needed in the production process.
