For example, the ongoing Russia-Ukraine conflict has caused supply chain disruptions for energy, grain, and fertilizer-related products. Or the frequent shutdowns of factories in China during the COVID-19 pandemic that caused shortages of various electronic goods globally. Some components are sourced from other Dash Automobiles factories specializing in producing these components. Meanwhile, some other components are sourced from third-party suppliers.
In fact, it can greatly affect your production plan or production schedule if not done right. Implementing and managing a JIT system requires careful tracking and organization. Manual tracking can be challenging so it is important to take advantage of software solutions. However, integrating new software can be costly and require extensive personnel training. Reduced planning complexity is achieved through the adoption of simple pull systems like Kanban, which can even extend to suppliers, minimizing the requirement for complex planning.
Advantages and Disadvantages of JIT
JIT focuses solely on estimating raw material requirements and aligning production inventories with production schedules. A “Pull System” is one of the core principles of Just-in-Time, where production and material replenishment are driven by actual customer demand rather than demand forecasts. In this system, each process only begins production when requested by the following process, ensuring that only what is needed is produced at the right time. This reduces excess inventory, minimizes waste, and improves operational efficiency. JIT also fosters a strong organizational focus on continuous improvement and customer value creation.
This reduces setup time and changes over time, streamlining the movement of materials on your production floor. To make the production process successful, you need to accurately track sales and predict customer demand. Failing to do so might result in selling products faster than you can restock them, causing inventory shortages. In the lean manufacturing model, there are eight types of waste that companies aim to minimize. Originally, seven of these wastes were identified in the Toyota Production System which focused on the production process itself. When lean methodology spread to the Western World, an eighth waste known as non-utilized talent was recognized which linked to how well management uses their staff.
JIT works best in environments where demand is relatively stable and predictable. For businesses that produce a wide variety of products with irregular demand patterns, implementing JIT may be more complex and less effective. They create goods directly related to the orders being placed, instead of making extra goods to meet the needs of any potential orders that may be placed. JIT requires careful consideration of its disadvantages as well as its advantages. Successful implementation of this system depends on the company’s logistics infrastructure and strategic planning.
This allows you to identify potential challenges and fine-tune processes before a full-scale rollout. Establishing dependable relationships with suppliers is the backbone of a JIT system. Manufacturers should partner with suppliers who can deliver materials promptly, always aiming for smaller, frequent shipments. Communication is key, and ProjectManager gives you live data for more insightful decisions. It’s ready to work when you are, automatically collecting real-time data, making the calculations and then displaying it in easy-to-read graphs and charts. While just-in-time manufacturing can be very beneficial, that doesn’t mean that JIT is without risks.
As soon as the order is confirmed, the supplier is informed and delivers just the right amount of parts needed. Once the parts arrive, the assembly team immediately starts building the laptop. After the laptop is finished, it goes straight to the customer, eliminating the need for storage at any stage. Each of these systems limit the total amount of work in process (WIP) in the system and also trigger production activities to occur just in time. Component kits are assembled just-in-sequence to match configurations ordered by customers. Deepen your understanding of the lean manufacturing doctrine through our free downloadable e-book.
Just-In-Time Manufacturing & Production (JIT): A Quick Guide
If a raw-materials supplier has a breakdown and cannot deliver the goods promptly, this could conceivably stall the entire production line. A sudden unexpected order for goods may delay the delivery of finished products to end clients. Ohno’s observations showed that simplifying processes reduced production errors and lowered costs.
- When lean methodology spread to the Western World, an eighth waste known as non-utilized talent was recognized which linked to how well management uses their staff.
- The first phase of any production process is to get the materials & components needed to make a product.
- You then move these post-it sheets in the Kanban board according to the production process in the assembly line.
- Unnecessary extra processing (for example, relying on inspections rather than designing the process to eliminate problems) Unnecessary motion of employees.

JIT reduces waste such as overproduction, excessive inventory, defects, and unnecessary transportation or energy emissions. Determine if your production processes can adapt quickly to changing circumstances. JIT thrives in environments with flexible production lines, versatile teams, and workflows that can scale up or down seamlessly. Analyse your industry for risks of sudden demand spikes or supply chain disruptions.
JIT vs. Traditional Production Methods
Learn effective strategies on how to identify bottlenecks in manufacturing processes. Discover key indicators, such as long wait what production system is preferred by just in time times, backlogged work, and learn to use why’ 5 times technique. In the just-in-time production process, everything must be standardized.
What are the benefits of JIT production?
- JIT addresses these challenges by focusing on producing and delivering goods only when there is a confirmed need.
- Kanban is a lean JIT production “nervous system” that controls work-in-progress production and inventory movement.
- This can be accomplished by using work management software that helps with time management.
- For JIT manufacturing to succeed, companies must have steady production, high-quality workmanship, glitch-free plant machinery, and reliable suppliers.
Just-in-time (JIT) is a production system developed by Toyota that focuses on reducing waste and improving efficiency by only producing and delivering products when they are needed. The goal of JIT is to minimize inventory levels and to avoid overproduction, which can lead to excess inventory and higher costs. Invest in inventory management software and systems that enable real-time tracking of materials and production schedules. This technology will help you stay on top of demand and maintain control over your supply chain. JIT manufacturing originated with Toyota production system in the 1970s and is rooted in the Japanese principles of lean manufacturing. This innovative approach broke away from traditional practices that depended on large inventories and mass production.
Improved quality control
Burger King franchisers keep a substantial inventory of hamburger ingredients on hand all the time, but a hamburger is only cooked when it is ordered. This saves waste and gives the chain bragging rights for the freshness of its food. 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. If you think about it carefully, a Restaurant can be a good example of a Just-in-time business. It seems very risky to produce in this way but lots of companies do it.
JIT businesses lack excess stock to fall back on which can lead to halted sales during unforeseen events. Making smaller, more frequent orders on customer’s demand under the production process can be pricier compared to buying in bulk occasionally. They focused on optimizing people, plants, and systems to achieve maximum efficiency. This meant involving every individual in the organization, arranging plants and processes for achieving maximum results, and scheduling production to meet demand precisely. For importers, costs add up at every stage—manufacturing, shipping, and warehousing—before a single sale is made. For instance, producing a batch of goods might take 30 days, shipping could add another 30 to 60 days, and then selling the product might take even longer.
The just-in-time production system is a lean manufacturing philosophy that seeks to synchronize a customer’s order with the entire manufacturing process of a product. This system ensures that all materials and components needed to manufacture a product arrive at the assembly line precisely when needed – not too early or too late. Just-in-time manufacturing is focused on efficiency, while lean manufacturing is centered on using efficiency to add value for the customer. The most important benefit of JIT is the elimination of raw material, inventory and product storage costs. Dell’s “build-to-order” model is another prime example of JIT production. Dell manufactures computers only when customers place orders, ensuring that no excess inventory is created.
In addition, he was fascinated by the then-new concept of American supermarkets. In supermarkets, customers can “pull” their desired product from the shelf, and a store clerk will simply refill it afterward. Identify areas where waste is occurring, such as excess inventory or slow lead times. This will help you understand where JIT can have the most significant impact. Implementing a JIT system requires investment in technology, training, and process changes.
Just in time is primarily the invention and success of Taiichi Ohno, who implemented the first concepts in 1949 and 1950. Learn about additive manufacturing and how it is revolutionising production. Discover the seven types of additive manufacturing and their advantages. Predictable demand and standardized processes allow seamless JIT adoption. Toyota pioneered JIT but remains among its most prominent practitioners. Supplier kanbans feed parts line-side as needed to minimise inventory.
