What Is Purchase Order Lead Time (POLT)?Purchase order lead time (POLT) refers to the number of days from when a company places an order for production inputs it needs, to when those items arrive at the manufacturing plant. Put simply, a POLT is the estimated time in which it takes to receive an order after it's placed. Purchase order lead times vary from company to company and from industry to industry, and depend on many factors such as the types of goods or materials being ordered, their relative abundance or scarcity, where the suppliers are located, and even the time of year.

Key Takeaways
Understanding Purchase Order Lead TimeAs mentioned above, the purchase order lead time is how long it takes for an order to be fulfilled—from the time the order is placed until the estimated date of receipt. So if a company places an order for supplies on May 1 and it's expected to be delivered on May 10, the POLT for the supplies is nine days. The POLT includes a number of different steps including the confirmation of the order, availability of the goods, the order placement, acknowledgement of the order, the shipping notice, receipt of the goods, invoicing, and payments. Companies must carefully plan purchase order lead times when planning a manufacturing run because if production inputs do not arrive on schedule, manufacturing will be delayed, costing the company money in lost sales, idle worker time, and lower factory overhead absorption. On the other hand, if inputs arrive too early, the company could incur additional inventory storage costs. For this reason, managers need to plan as precisely as possible when they need to order the materials needed, lest they incur additional overhead. If they have a trusted supply chain, this should be one of the first items added to a production and/or staffing calendar. There are ways companies can reduce the number of days in a POLT:
Special ConsiderationsA company can set up a two-bin inventory control system, which can largely automate the reordering process for small or low-value items or materials. For more important inputs, a company must keep in mind not only the shipment time but the order processing time as well. If supplies are ordered on Friday afternoon, the order may not be until Monday, which means a loss of two days. If raw materials are in scarce supply, a manufacturer may not receive the desired quantity, and they may not arrive on time if the supplier has to source the materials from somewhere else before it ships to the customer. If the inputs are coming from far away, the manufacturer must be aware of the possibility of a delay. If there is high seasonal demand for a particular raw material, that may affect whether supplies are received in a timely fashion. Even though a producer would like to avoid unnecessary storage costs, they might choose to keep a buffer supply anyway to protect against shipment delays. Visibility of real-time inventory levels of raw materials is enabled by online software connections between manufacturer and supplier who care about supply chain logistics. The more the buyer communicates its forward needs by providing demand forecasts to the seller, the more accurate the order lead times will be. Just-in-time (JIT) inventory and just-in-time manufacturing have been buzzwords in the world of supply chain for some time now, and quite a few businesses have adopted this approach. With growing competition and increasing pressure to boost profitability, many businesses have adopted this strategy to boost their bottom line—which can be problematic when supply chains come to a screeching halt. This article will cover:
What Is Just-in-Time (JIT) in Inventory Management?JIT is a form of inventory management that requires working closely with suppliers so that raw materials arrive as production is scheduled to begin, but no sooner. The goal is to have the minimum amount of inventory on hand to meet demand. Key takeaways from this article:
Video: What Is JIT Inventory Management?
Just-in-Time (JIT) Inventory Management ExplainedJIT inventory ensures there is enough stock to produce only what you need, when you need it. The goal is to achieve high volume production with minimal inventory on hand and eliminate waste. How Does Just-in-Time Inventory Management Work?JIT inventory management ensures that stock arrives as it is needed for production or to meet consumer demand, but no sooner. The goal is to eliminate waste and increase the efficiency of your operations. Since the main objective is often quality and not the lowest price, JIT requires long-term contracts with reliable suppliers. JIT is what’s known as a lean management process. In JIT, all parts of any production or service system, particularly people, are interconnected. They inform each other and are mutually dependent on generating successful outcomes. This practice’s origin comes from Kaizen, a Japanese term meaning “change for the better.” Originating in Japan, the business philosophy looks to continuously improve operations and involve all employees, from assembly line workers to the CEO. Like JIT, the goal is to reduce waste and improve quality. The JIT Process Diagram and StepsOrganizations may vary in how they implement JIT in their environment, but the general steps are the same. This diagram shows how the cycle of continuous improvement works in JIT inventory management. Steps in Cycle of Continuous Improvement for JIT Inventory
Advantages of JIT Inventory ManagementJIT inventory management boosts a company’s ROI by lowering inventory carrying costs, increasing efficiency and decreasing waste.
To support these goals, you can invest in new technology or update existing solutions that will link your system with your suppliers to coordinate the delivery of parts and materials. JIT Inventory MethodologyThe JIT inventory methodology uses a variety of techniques to smooth operations. The lean method focuses on optimizing organization, paying attention to detail, having small lot sizes, increasing transparency, fostering cell manufacturing and using a pull (rather than push) approach. Techniques Involved in JIT Inventory Methodology
Why Is Kanban a Critical Element for the JIT Inventory System?Kanban is the “nervous system” of lean JIT production, controlling work-in-progress production and inventory movement. Kanban is crucial when it comes to eliminating manufacturing waste due to overproduction. More traditional mass production methods use push inventory strategies based on the estimated number of expected sales. Kanban’s pull system creates more flexibility on the production floor because a company only produces goods based on actual orders. Kanban uses cards (paper or digital) to track the progress of production on a factory floor. As inventory moves through the manufacturing process, Kanban cards reflect that progress and can signal when it’s time to order more stock. Typical Kanban Board in JIT Inventory ManagementWhy Use JIT Inventory Management?Companies often adopt JIT inventory management as a cost-cutting strategy. When implemented correctly, JIT can create more value than traditional methods that require more extensive inventories. Learn more about inventory management controls. How Does Just-in-Time Inventory Management Improve Businesses?Just-in-time inventory management reduces waste, improves cash flow, increases flexibility, optimizes human resources and encourages team empowerment. Companies that are successful at JIT inventory management maximize profits by keeping investment in stock as low as possible. They use data to manage inventory. They use an ERP system to gather information on shipping, customer satisfaction, loss prevention, warehousing, purchases, reorders, goods in storage, receiving, stock turnover and more. Benefits of JIT Inventory Management
Disadvantages of Just-in-Time Inventory TechniquesJIT inventory management relies heavily on precise forecasting and strong relationships with key suppliers. When something goes wrong with either of those, that’s a problem because there are no backup options in place. For example, a single supplier that can’t deliver for any period of time can disrupt the entire supply chain and halt your operations. In addition, companies practicing strict JIT inventory management probably won’t have extra stock to satisfy unexpected orders. If an organization’s forecasting can’t account for a surge in demand, for instance, it won’t have the stock to fill those orders. That could mean lost revenue and, potentially, lost customers. Potential Risks of Just-in-Time InventoryThe primary risk of JIT comes from its philosophy. JIT inventory management requires everyone in an ecosystem and supply chain to commit and work cohesively. If any part of that arrangement breaks down, it risks the entire infrastructure.
Pros and Cons of JIT Inventory ManagementJIT inventory management has its pros and cons: less inventory saves money but relies on strong coordination between workers and suppliers. Also, strict protocols and forecasting requirements produce value, but various factors can disrupt it. Overall, the pros historically outweigh the cons unless there is a global supply chain disruption: Pros and Cons of JIT Inventory Management

History of Just-in-Time Inventory ManagementThe just-in-time philosophy was initially known as the “Toyota Production System” (TPS) or just-in-time manufacturing. The approach was developed in post-World War II Japan, when car manufacturing faced shortages and had to minimize resource consumption to survive and remain competitive. Eiji Toyoda and Taiichi Ohno, Japanese industrial engineers, created the system when Toyota Motor Company (TMC) recognized that U.S. carmakers of that era were outpacing their Japanese counterparts. After some testing, they established the Toyota production system and closed the gap between 1945 and 1970. JIT has continued to grow as a practice worldwide. This system’s basic underlying idea is to minimize the consumption of resources that add no value to a product. Figure 1.

Learn how to improve efficiency and boost profits with a leading inventory management system. JIT inventory has the potential to generate tremendous benefits for many companies. This approach has caught on since Toyota invented it because it can lower costs and increase profitability in a big way. To evaluate whether it’s a fit for your business, you should consider the pros and cons with your industry and business model in mind and whether the organization could support the processes required to make this work. JIT Inventory Management FAQsWhile JIT aims to create simplicity, understanding how to implement it, associated terms and related methodologies takes some effort. This FAQ answers common questions about JIT inventory management. What is a just-in-time inventory system?The JIT inventory system aligns production schedules with the delivery of supplies. These systems increase efficiency and decrease waste by receiving goods on an as-needed basis. What is the just-in-time method of inventory control?The JIT method of inventory control involves creating, storing and tracking enough orders to supply demand. JIT differs from other inventory strategies in that businesses don’t make and hold excess inventory in anticipation of future orders. What’s the difference between JIT inventory and JIT manufacturing?JIT inventory and manufacturing have a similar principle: produce or receive a product only when needed. They operate at different points in the supply chain but can work together or independently. What is the difference between just-in-time vs. just-in-case (JIC) manufacturing?JIT aims to reduce waste by only taking in inventory as needed for production. JIC prioritizes stocking surplus goods and outpacing the current demand to fulfill orders on time. What is the difference between just-in-time inventory vs. Economic Order Quantity (EOQ)?JIT ensures there is the right quality and quantity of inventory using minimum resources, time and material waste. EOQ is a formula used to identify stock replenishment levels to avoid shortages and extra costs. The EOQ regulates the most favorable inventory to produce or buy to minimize order and storage costs. The EOQ formula is useful for companies that have consistent demand, order and holding costs over time. What is an example of just-in-time delivery?Supermarkets take advantage of just-in-time delivery by only restocking a product once customers have bought nearly all available items. The demand for any item directly affects supply, meaning the market replenishes some goods on a regular basis and others infrequently. How does the Theory of Constraints (TOC) apply to JIT inventory management?TOC is a continuous improvement principle and process that identifies systemic weakness or variables. In JIT, the TOC pinpoints the weakest part or person that may constrain system throughputs.
