As with all inventory management techniques, using a just in time inventory system has both advantages and disadvantages. These steps help mitigate risks and ensure a smooth transition to a JIT inventory system, aligning closely with business efficiency and sustainability goals. Kanban is a Japanese scheduling system that’s often used in conjunction with lean manufacturing and JIT. Taiichi Ohno, an industrial engineer at Toyota, developed kanban in an effort to improve manufacturing efficiency. At the start of the COVID-19 pandemic and its ripple effect on the economy and supply chain, things like paper surgical masks, toilet paper, and hand sanitizer experienced disruption. This was because inputs from overseas factories and warehouses could not be delivered in time to meet the surge in demand caused by the pandemic.
Just in Time Inventory Control Model
When considering JIT inventory management, it is crucial to assess supply chain reliability, quality standards from suppliers, and production flexibility. The kanban system highlights problem areas by measuring lead and cycle times across the production process, which helps identify upper limits for work-in-process inventory to avoid overcapacity. Minimizing the amount of inventory on hand gives you more freedom in terms of cash flow, as you’ll have less working capital tied up in the various costs of purchasing, storing, and replenishing stock. You’ll also save on labor costs, as it takes fewer staff to manage a minimal inventory. If you’re using JIT, you won’t need much storage space for completed goods or materials. As soon as your workers finish assembling and/or packing the product, it is immediately placed on a truck for shipment to the customer.
While both methods have their advantages, they cater to different business needs and risk tolerances. Understanding the key differences between these two systems helps businesses choose the best strategy for their supply chain. While Just-in-Time (JIT) inventory offers cost savings and efficiency, it also comes with risks and challenges.
Advantages and Disadvantages of JIT
Because of this, JIT depends on accurate demand forecasting and planning, precise timing, solid supplier relationships, and efficient supply chain management. Just in Time operates with a customer-centric ethos, aligning production precisely with customer demand to minimize wait times and ensure products are available when needed. Its focus on quality, flexibility, and continuous improvement aims to meet evolving customer expectations.
JIT relies on you replenishing stock as soon as it’s sold, with no room for delays—so you can’t shop around for the best deal or wait until the price of materials drops. If your supplier decides to charge more than usual, there isn’t much you can do about it. By spending smaller amounts on these aspects, you can allocate more money to other business costs such as marketing. Although you need less cash on hand in JIT, you still need to have some in reserve in case of unexpected events. JIT is particularly useful for “fast fashion” companies such as Zara, which owns its supply chain and is able to bring goods to market in double-quick time. Because the firm designs and manufactures up to 50% of its range in mid-season, it can react fast to new trends and get items into stores before the bandwagon rolls on.
Dependency on Reliable Suppliers
Either way, you’re going to need a software solution like Brightpearl to help you make JIT work. This system typically uses Kanban (Japanese for “sign”), an inventory control system that involves tracking materials as they run out. It also focuses on streamlining and optimizing organization and communication—with continuous improvements to ensure high quality and customer satisfaction. For example, ThroughPut has AI-powered decision intelligence software that helps businesses implement JIT with ease, providing real-time insights to support inventory management aligned to JIT principles.
This strategy minimizes waste by aligning production schedules with raw-material orders. By producing goods only when needed, businesses can cut storage costs and improve efficiency. In this article, we dive into the principles of JIT, its advantages, and practical steps for implementation. Selecting the right suppliers and cultivating strong relationships holds paramount importance within a JIT system. These partnerships ensure timely deliveries, maintaining the precision required to avoid disruptions in production schedules.
Two core approaches, besides from JIT, are Just in Case (JIC) and Just in Sequence (JIS). As an order is received, the production process is triggered, and the materials are ordered for the specific order. Thus, as the order is placed, the materials and goods required are “pulled” through the supply chain. Your suppliers must be dependable, responsive, and capable of quick deliveries without compromising quality. So, consider diversifying your supplier base to ensure flexible, scalable solutions.
Industry 5.0 Brings a Shift to Human-Centered Innovation In Manufacturing
By keeping inventory levels lean, businesses can optimize their storage facilities and allocate space more effectively. By constantly striving to minimize waste and optimize processes, companies can enhance their overall productivity and quality. Just-In-Time (JIT) inventory systems optimize operational efficiency and minimize costs by aligning production closely with demand.
By not having a large inventory of parts and materials, manufacturers have more control over their production process. However, JIC and JIS have potentially higher costs and inventory levels to ensure this level of safety. There are various approaches to inventory management, some of which can be classified as either a “push” system or a “pull” system, dependent on the replenishment of inventory and production. A Traditional Push System bases production on forecasts or predetermined schedules. Goods are produced and “pushed” into the inventory based on these forecasts.
- Enhanced supplier relationships and a growing focus on sustainability have further shaped JIT’s evolution.
- They need to have a clear idea of your demand, which is why JIT requires accurate planning.
- Seasonal cash flow describes the fluctuation of your business’s revenue and expenses at different times of the year.
- If a supplier doesn’t deliver on time, it can cause production delays, unhappy customers, and financial loss.
- They risk running out of vital inventory and losing sales or stopping production.
This systematic approach ensures only what’s needed is produced based on actual orders, more flexibility, and efficiency. This methodology has since been adopted by numerous industries worldwide, making JIT a cornerstone of modern inventory management. The automotive sector was one of the first industries to adopt JIT, pioneered by Toyota in the mid-20th century. Car manufacturers receive parts and components just as they are needed, reducing warehousing costs and preventing overproduction. Different industries rely on JIT or JIC based on their operational requirements and risk tolerance.
B. Neither a just in time inventory system usually reduces costs for the supplier nor the producer, though it does lead to more flexibility for both.

Your whole business should be committed to the JIT principles, with all sectors working together in harmony. It’s crucial that everyone understands the benefits of JIT and how their role fits into the big picture, as well as knowing exactly how the processes should work. It’s also important that you stick with your plan—if you change the system at the last minute, your supplier may not be able to deliver on time. They need to have a clear idea of your demand, which is why JIT requires accurate planning.
Continuous Flow Manufacturing
- In manufacturing, for example, the distance between the storage of materials and the room must be rethought.
- JIT manufacturers rely on their suppliers to deliver goods on time and in the exact quantities needed.
- While they need to keep a certain amount of ingredients on hand, they can use demand planning to predict busy and slow times, thus reducing waste.
If you don’t know exactly what you have, you won’t be able to react quickly to unexpected orders. Local sourcing of goods is another way to reduce expenditure and free up extra cash. If your suppliers are located nearby, the goods you order have shorter distances to travel—meaning they should always arrive when you need them. Workers with diversified skills can quickly be deployed to different areas where they are needed most, in order to keep processes moving. Another advantage is that it encourages team empowerment, and helps staff stay committed to the shared success of JIT. Using electronic ordering systems to streamline communication and automate supply orders is also a common practice to ensure timely material availability.
Using Kanban in JIT brings several benefits, including production flexibility and waste elimination. Kanban and JIT together bring overall production efficiency by having products available without excess inventory. Technology, including AI, can help with real-time demand insights, supply chain optimization, and automation.
