Just-in-Time JIT: Definition, Example, Pros, and Cons

For them, there are Gantt charts, sheet views, task lists and calendars. Whatever project view you prefer, it’s kept up-to-date with the rest of your team. No one can pinpoint the exact date that just-in-time manufacturing began, but it stemmed from post-World War II Japan. The war left Japan without the working capital to finance big-batch production methods that were the norm in other developed nations. By designing and managing the cell in this way, maximum labor productivity can be preserved even if customer demand changes over time. Instead, we use pull systems–commonly called kanban–to trigger the movement of material so it is created and delivered just in time and still in small quantities.

• Burger King franchisers maintain a large inventory of hamburger ingredients on hand at all times, but a hamburger is only cooked when ordered.
• Yet, it’s also an incredibly challenging system to follow – and highly risky”.
• The roots of JIT can be traced back to the Toyota Production System (TPS) pioneered in Japan following World War 2.
• As previously mentioned, the just-in-time production system follows the pull system method.
• Kanban is a scheduling system that is frequently used in conjunction with JIT to prevent overcapacity during the process.

Your workforce needs to be trained on JIT principles, including how to work efficiently in a demand-driven environment. Increased the Return on Total Assets (ROTA) and reduced overall inventory costs.

How to Implement a Just-In-Time Manufacturing System

The just-in-time (JIT) inventory system minimizes inventory and increases efficiency. JIT production systems cut inventory costs because manufacturers receive materials and parts as needed for production and do not have to pay storage costs. Manufacturers are also not left with unwanted inventory if an order is canceled or not fulfilled. Apart from Toyota, Dell Technologies also stands out as a successful example of the Just-in-Time system. Dell has been a pioneer in offering customized products by applying the JIT philosophy in computer production.

OneAdvanced offers manufacturing software tailored to support lean manufacturing. These tools streamline supply chain management, enhance real-time visibility, and optimise production processes – everything a company needs to succeed with JIT. By reducing complexities and automating inventory tracking, our Cloud-based solutions empower manufacturers to focus on delivering high-quality products swiftly and efficiently.

Once the Kanban board has been divided into these sections, you can attach Post-it sheets to this board. You then move these post-it sheets in the Kanban board according to the production process in the assembly line. When implementing the just-in-time production system, a Kanban board helps significantly. This system is relevant to the pull system in production, where goods will only be produced once confirmed customer orders are placed.

Just in Time Manufacturing

Therefore, they don’t use up raw materials that may or may not actually be necessary to fulfill the orders they have. In turn, it cuts down on the costs they have for inventory, freeing up cash flow. Just in Time (JIT) is a management philosophy that aims to minimize inventory in production and logistics processes and deliver the needed materials just in time. The basic principle of JIT is based on the understanding of “right time, right quantity, right place”. This method eliminates the need to keep extra stock on the production line, thus reducing costs and increasing productivity.

For instance, an electronics manufacturer might order parts for assembly only once a customer places an order. This reduces storage costs, limits waste, and maximises efficiency – all while meeting customer requirements on time. The car manufacturer implemented this model to produce parts only when necessary, aligning inventory orders with customer demand. The system streamlined operations, enhanced efficiency, and minimised waste. Using more efficient workflows is part of having a better planned-out facility that can handle your production flow. This can be accomplished by using work management software that helps with time management.

Understanding JIT Manufacturing

Adopting lean manufacturing principles and continuous improvement strategies will ensure you maximise the benefits of JIT while reducing unnecessary costs. JIT manufacturing isn’t just a production strategy — it’s a mindset that redefines how businesses approach resource management, inventory control, and production workflows. It centers on producing the exact quantity of goods needed, precisely when they are required, while eliminating unnecessary waste. In the fast-evolving world of manufacturing, companies continuously seek ways to enhance productivity, cut costs, and maintain a competitive edge. In traditional manufacturing we try to predict what the customer will want and we will create a forecast (or guess) against which we will produce our products.

Our dedicated account managers provide personalised, responsive support to source industrial automation parts quickly. By leveraging industrial automation suppliers like us, manufacturers can more seamlessly transition to demand-driven just-in-time production systems. In summary, a Just in time production system is a transformative production strategy focused on precisely aligning output with demand through elimination of all forms of excess and waste. When purposefully implemented, JIT enables leanness, flexibility, quality, and cost-competitiveness.

• One of JIT’s greatest advantages is its ability to align supply with actual market demand.
• Nonetheless, it’s essential to balance supplier competitiveness and supply chain security.
• Machines can work faster, more precisely, and longer with less downtime than an average shop floor employee.
• Either way, they must arrive at their destination immediately so your plant doesn’t need to store them.
• Many industries have adopted JIT manufacturing to stay efficient and reduce costs.

A common hindrance to establishing flow and pull for just in time manufacturing is long changeovers. To see what we mean, checkout our most popular YouTube video on converting batch-and-queue manufacturing to a continuous one-piece flow operation. Arguably the most popular of just in time concepts is the idea of continuous flow, or what is also called one-piece flow.

Step 1: Assess your ability to forecast demand

So to regulate the speed of all activities in the system, a standard pace is determined called takt time. Takt is the German word for “meter.” If you’re a musician and familiar with a metronome, that’s precisely how takt time works. But as the batch size is reduced to an ideal size of one, what production system is preferred by just in time some extraordinary things happen.

The JIT system works by coordinating production schedules closely with supplier deliveries and expected customer buying patterns. By adopting JIT manufacturing and lean principles, companies can cut production costs and enhance their competitiveness. JIT production is closely linked to lean waste management, which targets the seven wastes identified by Toyota engineer Shigeo Shingo. By making only what’s needed, when it’s needed, and in the right amount, this process reduces inventory, overproduction, and defects. It also improves material flow and reduces transportation, unnecessary movement, and overprocessing.

Taiichi Ohno, an industrial engineer at Toyota, developed kanban in an effort to improve manufacturing efficiency. The just-in-time inventory system is different from the just-in-case system, 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. For example, McDonald’s has adopted a made-to-order food preparation system using the JIT approach.
