Just-in-Time Inventory: What It Is, and How to Implement It

by Corynn Anderson in August 3rd, 2022

Having good control over inventory is essential for the proper functioning of any business. In this article, we'll talk about the Just In Time Inventory (JIT) method. This method requires that managers are in tune with a company's operations and the nuances of its environment, including customer behavior. Such visibility into a company's operations for successful JIT inventory management often requires a technology investment.

In modern business models where physical stores are connected to online channels, such as the buy-online-pickup-in-store (BOPIS) fulfillment method, it is even more challenging to have accurate inventory visibility. When a retailer doesn't have full visibility into its inventory-related processes, relationships with its suppliers can be strained, and the customer purchase experience can be negatively impacted.

Most companies build and hold excess inventory as a way to ensure that orders can be fulfilled. Alternatively, Just-in-Time Inventory helps companies cut unecessary costs and reduce waste by making sure that nothing is produced, transported, sold, or purchased any earlier than is absolutely necessary.


How Does Just-in-Time Inventory work?

The Just in Time Inventory method involves creating, storing, and controlling only enough orders to supply the actual demand for the company's products. Just in time is a method that fits better for some industries than others. So, let's take a detailed look at how it works and whether it's the right choice for your company.

Process timing Time

In just-in-time, each step of the production process needs to feed into the next at just the right time. Therefore, it is necessary to have complete control over the lead time — identifying opportunities for improvement in advance so that everything is produced as quickly as possible.


But remember, it's not just about speed. You need to know that your team can maintain quality even in times of high demand. Applying just-in-time inventory requires a high response from your productive and administrative team. Therefore, your company's workforce must be well qualified, able to handle an on-demand operation.


Just in time depends not only on processes and employees but also on how your company thinks about its own spaces. The shop floor layout needs to facilitate an efficient workflow. This means that your factory must be rethought in all production scenarios, from how inputs come in when shipments arrive all the way through to how merchandise leaves the warehouse and is shipped.


Quality control plays a fundamental role in the success of the just-in-time inventory method since agility is just one of the pillars of the strategy. It is necessary to know how to align speed with proper quality controls for effective process execution. The objective is that the quality remains the same (or improves) even when the operational demand increases.


Finally, all the orchestration of processes necessary for the success of just-in-time inventory management is based on your suppliers' capacity to fulfill your demand. If your company plans to implement JIT inventory management, it is important to have suppliers who are capable of quickly meeting your needs. If you haven't already, you will need to build a close trusting relationship with your suppliers — so that they understand your production methodology and can handle demand at all its stages, from production to logistics.


Just-in-Time Success

JIT is a model approach that helps to optimize processes and can be adapted to different business models. Today, many companies employ just in time in their production models.

One example is Apple. By reducing the amount of available inventory, Apple is less likely to overstock. This is something Apple CEO Tim Cook talks about. For the executive, the stock is a problem native to companies: "The inventory is fundamentally bad. You want to manage like you're in the dairy business. If you go past the updated date, you have a problem."

Another example is Tesla. With total control over its supply chain, Tesla can customize all of its production to operate on demand, keeping very little stock. Thus, it significantly reduces the costs associated with holding stock. Another factor that the company incorporates to "improve" the on-demand operation is the possibility of customization. Tesla offers customers exclusive extras to personalize the car. In this way, the company positions itself as an innovator in the segment and justifies its delivery deadlines.


Benefits of Implementing JIT Inventory

Great, so JIT Inventory Management worked for Apple & Tesla, but their successes don't offer a full picture of the method or how it might play out for other businesses. A few key advantages that just-in-time inventory management could bring to your companyare:

  • Optimized Inventory Management - The company's purchasing dynamics will follow demand, which makes it easier to manage the storage of goods and supplies.
  • More Effective Processes - Your business will benefit from having all of your processes mapped standardized, promoting efficient process execution while increasing product quality.
  • Reduced Waste - Companies using just-in-time inventory are often able to reduce waste, prevent excess stock, and avoid devaluation of merchandise or unnecessary storage costs.
  • Improved Allocation of Labor Hours - JIT Inventory improves your team's performance, by orienting labor allocation around prioritized projects with high production value.

Again, companies use the just-in-time method so that their production is directly aligned with the orders placed. This way, it is not necessary to manufacture additional products to meet the needs of any potential orders that may or may not be placed. When inventory is managed like this, costs are reduced through controlling excess and increasing profitability. By increasing inventory management efficiency, retailers can reduce waste by avoiding failures during peak sales periods.


Tips for Implementing Just in Time Inventory

In order to successfully implement JIT inventory, remember to take steps that will prepare your company for the changes such as training employees, adapting to new technologies, and using a management system.

  • Identify the Scope of Change: Some companies are in a good position to implement JIT inventory, some have to slowly adapt processes across a 5-10 year period, and for other companies, JIT inventory just isn't the right fit. How much would JIT inventory require your current business to change? Would the return-on-investment be enough to justify the change?
  • Qualification: Adopting a new work methodology requires assimilation and training. Therefore, it is essential that all the people involved can be properly trained in order to avoid process failures and other operational bottlenecks.
  • Communication: Be ready to review and continuously align the method, whether with suppliers, employees, or customers. You will need to be ready to rely on concrete and reliable KPIs, and establish good communication across your organization when changes need to be made.

By thinking through topics like those addressed here, you can make sure your organization is prepared for change, and your shift to JIT inventory will go much more smoothly. More important than any of these tips for preparation, however, is having the right technology in place to handle the JIT inventory method.


Using Technology to Apply Just-in-Time

A good ERP system makes it possible for managers to monitor the entire production chain including machines, deliveries, suppliers communications, and much more. By integrating with other company sectors, such as inventories and sales, the entire production flow is improved.

Five Advantages of Investing in Management Software

Just in Time Inventory requires an organizational culture focused on agility in the execution of processes. Therefore, technology can be an excellent ally. Here are some of the advantages of implementing a high-quality inventory management technology when pursuing the JIT Inventory management method:

1. Production on Demand

Controlling business processes using archaic systems can lead to serious problems with Just-in-Time Inventory. Without real-time insights into customer orders and fulfillment progress, you won't be able to meet demand, and customer satisfaction will decrease.

Producing on demand is not a simple process — it especially requires extensive integration of information that facilitates communication across industries. However, by implementing good business management technology, you'll be able to manage this entire process, end-to-end in an efficient and effective manner.

2. Planning Process Steps

So, how does a business put production planning into practice? With software, managers can more easily identify potential problems or opportunities in each step of production operations. Process steps can then be revisited, refined, and planned out again in an improved fashion.

3. Inventory Optimization

Inventory optimization does not happen automatically in a company that employs just-in-time inventory management. Inventory must first be very well monitored. Management software gives more transparency to this process, enabling a broad view of the items in stock and what will go into production and should be replaced.

4. Elimination of Manual Errors 

By having greater control over processes, employees can reduce the frequency of manual errors by employees. Management software allows for the automation of several tasks. This not only eliminates human errors within those automated tasks, but also frees up the time of individuals who can now dedicate that time to other value-added tasks that help to improve the overall quality of outputs.

5. Constant Monitoring

The proper management software offers a high level of monitoring of the company's production and results. In this way, the manager has in-depth data on the performance of each area at hand, which allows for better and more efficient decision-making.
