Lead Time Definition and Formula What Is Lead Time?
Improperly managed lead time in inventory management can cause a lack of stock (read more about backorder meaning), canceled orders, delays at the online marketplace level, and loss of revenue. ARO, or after receipt of order, is the point that the supplier receives the order. Any actions taken between ARO and the delivery of goods are a part of the lead time for that order. This starts the clock on production and is the first substantial number when measuring lead time.
All of those will help you stay on top of the moving parts, avoid delays, and maintain a reasonable lead time for any sort of project or process. But you’d rather err on the side of estimating a higher lead time and delivering early than estimating too low and dealing with missed deadlines and disappointed customers. It’s always better to underpromise and over-deliver, rather than the other way around.
Lead Time In Supply Chain
With kitting services, inventory items are grouped based on their specific use in the project. Workers save time choosing from smaller lots of parts, keeping production more organized and efficient. Although people use them interchangeably, lead time and delivery time aren’t the same. Lead time is the elapsed time in a defined business process, which can include delivery but doesn’t have to.
Besides making sure resources are distributed evenly, managers can prioritize tasks, delegate work and communicate more effectively. The components of lead time are not set in stone as they can vary from one industry to the next.

A waiter guides him to a table, gives him the menu and asks what he would like to order. At that moment the customer has made an order which the restaurant has accepted – Order Lead Time and Order Handling Time have begun.
Finding this lead time in inventory management requires adding the supply delay with the reordering delay. It’s always ideal to always have enough supply on demand to feed the manufacturing process and keep the production flowing. In the manufacturing environment, lead time has the same definition as that used in supply chain management, but it includes the time required to ship the parts from the supplier.
As customers have come to expect fast delivery times, if you can shorten customer lead time, you can increase sales. Though there may be similarities, the lead time changes based on various processes. One thing that all industries have in common is that lead time allows businesses to schedule work and give their clients or end-users a deadline by which they’ll receive the product. Effectively managing material lead time involves coordinating with suppliers, maintaining accurate inventory levels, and implementing strategies to mitigate potential delays. Lead time and cycle time are both important concepts in manufacturing and business operations, but they focus on different aspects of the production process.
- Data reveals the average material lead time was 100 days – the longest ever recorded since records began in 1987.
- The reports are also easy to share as a PDF attachment or even print out to keep stakeholders updated on progress.
- You’re probably getting a grasp that lead time itself is a pretty broad concept — and it’s one that’s highly customizable and adaptable to a huge variety of teams, situations, and industries.
- Lead Time terminology has been defined in greater detail.[7] The Supply Chain from customer order received to the moment the order is delivered is divided into five lead times.
As a quick example, drafting a blog post might take three days while editing takes two days. what is lead time By implementing a combination of these strategies, businesses can effectively shorten lead times, improve customer satisfaction, and gain a competitive advantage in the market. You can take several strategic actions to shorten lead times and improve overall efficiency in delivering products. These can be performed on an ongoing basis to achieve a system of continuous improvement.
Pinpoint dependencies and simultaneous tasks
These strategies can help improve overall competitiveness, increase orders, and reduce costs. When delivering products, long lead times can negatively impact customer satisfaction, regardless of product quality. When faced with the option of waiting months for their preferred product or receiving a comparable alternative immediately, most customers will choose the readily available option. When dealing with inventory management, you’ll include the supply delay and the reordering delay.

The most important thing for anyone trying to manage inventory is to track average lead times and act quickly when any variances are found. Keeping lead times minimal can save businesses thousands of dollars from the loss of sales to halted production runs. Lead time issues are a headache no matter where a business is in the supply chain, whether it’s the food supply chain or high demand products in eCommerce. Extended lead time can cause several problems that interfere with a business’s ability to fulfill orders. With uncontrolled lead time, it is impossible to ensure you purchase the optimal economic order quantity, or EOQ.
How Does Lead Time Affect Cost?
Efficient inventory management is necessary to maintain production schedules and meet consumer demand. Stockouts occur when inventory, or stock, is unavailable preventing the fulfillment of a customer’s order or product assembly. Production stops if an organization underestimates the amount of stock needed or fails to place a replenishment order and suppliers cannot replenish materials immediately. Additional automation steps may include alerts when inventory reaches a certain level, critical errors during product testing, or customer feedback triggers. For smoother delivery, incorporate lead time impact automation as a standard project management function. Optimizing the supply chain can lead to greater resilience, fewer disruptions, defined mitigation plans, and rapid recovery, all of which contribute to shorter lead times.
There isn’t one way to calculate lead time, but the most common is to subtract the order request date from the order delivery date. Understanding lead time is an important part of the process, but the real magic happens when you start to figure out ways to minimize your lead time. Doing so means you can streamline your operations and get products or projects across the finish line even faster.
In project management, it could mean booking a freelancer on a retainer so you have first priority in their workload. If you aren’t in manufacturing, you can apply a similar concept to any sort of project process or business process management. For example, maybe you can partner with a freelancer for a specific skill rather than needing to wait for an in-house team member to be available. It’s essentially your “backup” stock that you can tap into if you experience supplier delays, an unexpectedly large order, or any other unanticipated events that could throw your inventory off track. You’re probably getting a grasp that lead time itself is a pretty broad concept — and it’s one that’s highly customizable and adaptable to a huge variety of teams, situations, and industries. But, generally speaking, you can think of lead time as the amount of time that passes between the start of a process and the end.
Lead time is rarely accounted for in the EOQ model because it’s impossible to standardize lead times across industries. That being said, it’s necessary to incorporate lead time into your EOQ whenever possible. With a keystroke, you can dive into project status, portfolio status, workload, costs, tasks and so much more.
