The most important factor when trying to reduce lead time is looking at your historical data. These numbers can help you determine average lead times and help you discover where lead times are increasing so you can head them off. Lead times are an essential part of the manufacturing process and can significantly impact the speed at which products are brought to market. Companies should consider all types of lead time when planning production to ensure they can meet customer demand in a timely manner.
- These programs often come from an off-site supplier, using just-in-time (JIT) inventory management for ordering and delivering components based on usage.
- Several formulas can be used to calculate the different types of lead time in supply chain management.
- By optimising material lead time, businesses can ensure a smoother and more efficient production process while minimising disruptions and maintaining consistent product availability.
- Here we break down what lead time is, the types of lead times in supply chain management, the factors that affect lead time, and how to shorten lead times to provide a better customer experience.
Lead time definition: What is lead time?
Short lead times generally indicate fewer bottlenecks and greater operational efficiency, while long lead times indicate opportunities to fix or remove inefficient workflows and tactics. Production takes time, shipment takes time, and any other intermediary steps take time. As such, lead time in inventory management needs to be monitored and planned for.

Receive instant notifications about the status of your inventory and process orders faster and more efficiently — no coding required. Color code different sections to gain instant clarity on where an order is in the fulfillment process and what action needs to be taken next. This is because manufacturers need to know exactly when parts requested are ready to be constructed with other parts, using the most efficient manufacturing practices. And when it comes to keeping supply levels ample or turning around a lengthy assignment, you’ll want to apply a deeply scientific lens to your timekeeping. You can lead a horse to water, but you can’t make him fulfill orders in a timely manner. Using offsite assembly in overseas markets instead of shipping completed goods can help companies save money on tariffs.
Components of Lead Time
This can cause further delays with subsequent orders leading to ever-growing lead times and unhappy customers. The main types of lead time are customer lead time, material lead time, factory, or production lead time, and cumulative lead time. The first three types of lead time are summed to arrive at the fourth type of lead time. Transportation lead time is the amount of time it takes for a shipment to move from its point of origin to its destination. This includes the time it takes for the product to be shipped from the manufacturer, go through customs and other regulatory processes, and finally reach its destination.
By optimising material lead time, businesses can ensure a smoother and more efficient production process while minimising disruptions and maintaining consistent product availability. The goal in managing delivery lead time is to ensure that products reach customers within the timeframe that aligns with their purchase expectations. This involves coordinating logistics, optimising transportation routes, and addressing any potential obstacles that could extend the delivery timeline. The distinction between long lead time and short lead time boils down to how long a process takes to complete from start to finish.
Now the waiter marks the order in the cash register, rips the paper from the notepad, takes it into the kitchen and puts into the order queue. The order has been handled and is waiting in the factory (kitchen) for manufacturing. As there are no other customers, the waiter decides to stand outside the kitchen, by the door, waiting for the dish to be prepared and begins calculating Manufacturing Lead Time.
Customers
Regardless of the specifics, it’s all about keeping those bonds strong so that you can get what you need when you need it and lower your lead time. Because lead time means so many different things in different industries, there also isn’t one default way to reduce it. However, there are several strategies that have proven effective and are worth a try. We don’t blame you — there’s a lot of math involved in figuring out your lead time, but it’s important to ensure that all of your timelines and plans are based on reality rather than best guesses. So, when your inventory of that specific running top reaches 1,547, you know it’s time to place another order — so you can have what you need for your customers, without ever running out.
Lead time definition is the amount of time that goes by from the start to finish of any given process. In business, this means the amount of time that passes between a customer placing an order and the products getting to them. Lead time in shipping is the period of time between when an order is first received and when it reaches the customer. It includes the processing of the order and then the time spent delivering a package. Imagine a large festival that takes place during the first week of August every year that attracts 100,000 people on average and typically sells 15,000 festival T-shirts. Help with inventory management is one of the many benefits to working with a 3PL.
Lead time scheduling allows for the receipt of necessary components to arrive together, and reduces shipping and receiving costs. Shipping obstructions due to raw material shortages, natural disasters, human error, and other uncontrollable issues will affect lead time. For critical parts, a company may employ a backup supplier to maintain production. Working with a supplier who keeps inventory on hand while continuously monitoring a company’s usage helps alleviate the issues resulting from unanticipated events. Lead time is the elapsed time from the start of a process to its completion. It can be applied to any process in which a set of actions takes place.
Transportation lead times can vary significantly depending on the mode of transportation used, the distance the shipment has to travel, and other factors. Customer lead time is approached differently in make-to-stock (MTS) and make-to-order (MTO) production modes. In MTO, production lead time signifies the expected time frame from customer order through production until delivery. In MTS, however, customer orders are fulfilled from stock, which is then replenished with another manufacturing order. Make-to-Stock lead times are therefore much shorter than those of make-to-order companies. However, when it comes to satisfaction, the most important lead time is how long it takes to reach the customer.
Companies can use lead times to their advantage by utilizing automation and optimizing processes. Automation can help to reduce lead times by streamlining the ordering, manufacturing, shipping, and delivery processes. Automation can also help to reduce errors and increase the accuracy of lead times. In addition, companies should optimize their processes by identifying and eliminating supply chain bottlenecks and by streamlining their operations. Whether you’re working in project management, manufacturing, supply chains or inventory management, you need to deliver something valuable to your customers.
For customers, it can mean the time it takes to receive an order after they have purchased it. For product sellers, it can refer to how long it takes to receive raw materials or bulk products after placing a purchase order with a supplier. Lead time describes the amount of time it takes to complete a specific process. In business, lead time is often used to describe the amount of time it takes to process an order, manufacture a product, delivery a good, or a combination of these processes. Companies with shorter lead time may have less finished inventory on hand, more efficient processes that may cost less, and generally happier customers.
The material lead time is the amount of time between when a company becomes aware of a need for raw materials and when the materials are physically obtained. Companies are often alerted by inventory management systems when orders are processed. This lead time may be influenced by information systems that notify management when current inventory levels are low. It may also be impacted by ordering, shipping, delivery, and fulfillment by what is lead time suppliers. For example, if regulatory reviews affect your lead times, determine the rate of rework your finished products undergo.
