companies that use a just-in-time (jit production system): Corporate Policy of MM JIT Kanban Tutorial


By using this, Ford, Toyota and Unilever managed to thrive while maintaining a sizable market share. In the tech and hardware universe, Apple and Dell both use JIT and are at the top of their game. After it was pioneered in Japan, JIT inventory systems have been used by businesses all around the world.


The current pandemic put a major spoke in the wheels of JIT in manufacturing or automobile companies. So, in this article, I would like to discuss the basic assumptions of this concept and why the pandemic affected it so badly. He is constantly striving for excellence in his chosen domain and working hard towards his goal to taking Green Dot to the next level.

  • As continuous improvement is practiced, it decreases the unnecessary steps in the process of production.
  • But to achieve its full potential, the nation must continue to focus on improving its economy and ensuring that it develops strong ties with international partners.
  • JIT depends heavily on supplier efficiency and so isn’t an inventory management option for all types of businesses.
  • JIT inventory is a part of the inventory management techniques and is also considered one of the effective techniques for it.
  • Moreover, it needs reliable suppliers that can always deliver parts quickly, and the ability to quickly assemble machines that put together its vehicles.
  • For instance, a Kanban system is not extended to dealerships or deployed across tier I, II and III suppliers.

The advantages of lowering the investment in inventory are considerable, which can lead a company to pare away too much inventory. When this happens, any unwanted disturbance to the flow of materials can bring operations to a stop almost immediately. As a result, JIT concepts should be followed, but be aware that there is a lower limit on how far you can lower inventory levels. The elements of JIT, when applied to inventory, make sure that parts or raw materials arrive at the shop only at the point of required use or when they are needed. Not only does this help with inventory control and costs, but also with inventory storage matters. JIT is considered to be a “pull” system of manufacturing where production takes place only when there are requirements from downstream operations and specific demands from external customers.

Advantages Of Just-In-Time Inventory Management

The just-in-time inventory system is a management strategy that aligns raw-material orders from suppliers directly with production schedules. Companies employ this inventory strategy to increase efficiency and decrease waste by receiving goods only as they need them for the production process, which reduces inventory costs. The tendency to produce more waste in the production units is common while producing final goods from raw materials and other items. In this case, employing the just-in-time inventory management method reduces wastage in production units, leading to a more effective and efficient production process. Having said that, I believe JIT, in its current form, is not a robust concept / methodology / management philosophy for the future.

Does Zara use just-in-time?

Known for staying ahead of the trends, Zara changes its apparel designs every two weeks on average; most of its competitors do so every 10–14 weeks. To maintain this lightning pace, Zara utilizes Just-in-Time (JIT) production methods to keep turnaround times as tight as possible.

Inventory management ensures that the necessary supplies are available to fulfill consumer demand. After receiving an order confirmation, the company contacts its normal vendors to locate raw material stock. Every business has its own unique requirements and implements inventory management processes accordingly.

Make Sure To Have Reliable Suppliers

TallyPrime has features such as warehouse management, bill of materials, batch-wise and stock-wise management, reorder level, job-work management, and much more. The apparel industry uses JIT as it must ensure it is aligned with the trends that change rapidly. This allows them to store only what is necessary and reduce unnecessary expenditure on clothes that may be out of fashion. The fast-food industry especially franchises use JIT because it allows them to use fresh ingredients rather than store ingredients for long periods. Retail uses JIT because it allows it to store sufficient inventory thereby cutting costs of storing more than necessary. Another industry where JIT is used is manufacturing where production costs are high and using JIT minimizes inventory to improve efficiency.


When a job completes its process in a workstation, then it is pushed to the next workstation where it requires further processing or storing. In this system, the job has a job card and the job card is transferred stage by stage according to its sequence. In this method, due to unpredictable changes in demand or production hinder-ness, the job happens to deviate from its schedule and it causes accumulation of work-in-process inventory. Hence, inventory planners pessimistically fix the safety stock level on the higher side. Nevertheless, this decision is difficult due to the abundance of the available methods and the factors that should be taken into account.

The Elements Of JIT Inventory

But, in reality, the concepts are difficult to implement because of the need for fundamental organizational changes Wafa and Yasin. The factors that hinder the implementation of JIT in the manufacturing environment have been grouped into four categories. It is an approach, which is demand-driven and encourages flow type production. It is also described as a drive to simplify the manufacturing system in order to quickly detect the problems and force immediate solutions. Just in Time Manufacturing – also known as “lean manufacturing” refers to a system of manufacturing in which products are not built until the product is ordered and paid for. Some companies that have successfully implemented JIT include Toyota, Dell and Harley Davidson.

Then the teams are informed about their roles and responsibilities in the JIT process. Once all of these steps are complete, the refining stage takes place whereby the production is made more efficient. The warehousing industry is a sector of the economy that is responsible for the storage and distribution of goods and products. Warehouses are used by businesses to store and organize their inventory, as well as to facilitate the transport of goods to customers. Warehouse workers are responsible for receiving and sorting incoming goods, packing and shipping orders, and ensuring that the warehouse is organized and clean.

What is just in time technology?

In a companies that use a just-in-time (jit production system) model, only necessary stocks are acquired and therefore less working capital is needed for finance procurement. So, because of the less amount of stock held in the inventory, the organization’s return on investment would be high. The Just-in-time model uses the “right first time” concept whose meaning is to do the things right the first time when it’s done, thereby lowering inspection and rework costs. This needs less amount of investment for the company, less money reinvested for correcting errors, and more profit generated out of selling an item.


The just-in-time inventory system is a management strategy that minimizes inventory and increases efficiency. JIT, as previously stated, is good, and many well-known firms have found success with this inventory management strategy. A lot of pressure is exerted on them, as the supplier of the materials have to be ready with ample quality material, as the need arises. In the meantime, he pointed out that with the just in time model, the investment in inventory can be controlled, which in turn will reduce the interest cost and the turnover ratio will improve.

Journal of Operations and Production Management, Vol.23, pp. 418–429, 2003. Evolutionary implementation process supported by management, careful data migration strategies and cultural readiness.

Which company is successfully using JIT systems in its operations?

Toyota. Toyota was the first to implement JIT effectively in 1970 and is still one of the most successful companies practising JIT systems.

This chapter gives an overview of JIT system in which all these aspects are taken care of. With very low stock levels meaning that there are shipments of the same part coming in sometimes several times per day, Toyota is especially susceptible to an interruption in the flow. For that reason, Toyota is careful to use two suppliers for most assemblies. Thus, a strong, long-term relationship with a few suppliers is preferred to short-term, price-based relationships with competing suppliers.

Just-in- manufacturing keeps stock holding costs to a bare minimum. The release of storage space results in better utilization of space and thereby bears a favorable impact on the rent paid and on any insurance premiums that would otherwise need to be made. JIT is observed as a near perfect situation achieved by continuous elimination of the wastes. In India also, the research people are working for implementation and deriving benefits of JIT Technology in Manufacturing Industry as well as service sector.


Because inventory is maintained to a minimum, the IT method proclaims “absolutely no tolerance for errors,” making rework difficult in practice. JIT emphasises the “right-first-time” approach in order to reduce rework and inspection expenses. JIT necessitates that your staff comprehend the process, which necessitates some effort on your part in order to effectively teach your employees. Chances are quite high of not meeting an unexpected increase in orders as there will be no excess inventory of finished goods.

In JIT, the parts of the production or service system are interconnected. These systems exchange information and are mutually dependent on generating successful outcomes. It is a continuous improvement process aiming to streamline the business strategy. As stated earlier, JIT is excellent and many renowned brands have found success with this inventory management method.

How does Toyota use JIT?

Toyota sends off orders to purchase production parts only when it receives new orders from customers. Toyota and JIT manufacturing will succeed as long as the company maintains a steady production rate, with high-quality workmanship and no machine breakdowns at the plant that could stall production.

Nanda highlighted that with many small and big enterprises adopting technology, the disruptions caused in the supply chain and distribution sector will be dealt with easily and will give rise to a better JIT system. He added that for critical items, there is a strong need to look at single vendor / single country + 1 strategy to manage business risk. Let us visualize the supply chain of any manufacturing/ automobile company as having three major entities – Suppliers, the OEM and Dealerships. He and his team has helped us to make a great change In my industry and help in improving our working systems to a great extent. The new philosophy of JIC extends well beyond supply-chain management, however.

By focusing on value-added processes, JIT is able to achieve high-volume production of excessive-quality, low-value merchandise while meeting precise buyer needs. JIT helps enterprise house owners lower your expenses and scale back wastage, whereas still providing their prospects with the merchandise they need and need in a well timed method. A just-in-time inventory system works efficiently when the resources are wasted to a minimum.

Post-World War II, Japan was in search of to rebuild industry however was short on cash and space. Rather than financing the big-batch, large stock manufacturing methods used elsewhere, they built smaller factories that only housed the necessary supplies to fill existing orders. Toyota played a key position in developing simply-in-time manufacturing in Japan and introducing the tactic to the United States; because of this, it is often referred to as the Toyota Production System . JIT is a typical inventory management approach and type of lean methodology designed to increase effectivity, cut prices and reduce waste by receiving goods only as they are needed. The delivery lead time is the total time elapsed between placing an order and receipt of goods. The time can be reduced if developing a supplier network is located near the production site.

Does Starbucks use JIT?

JIT philosophy is used beside lean manufacturing, in other systems too. A great example would be McDonald's or Starbucks serving. When a customer places an order they starting to prepare the food or drink for serving.
