Lead Time

Also known as: leadtimes, project lead time

Definition

The total time that elapses from when a request is received to when it is fully delivered to the customer.

The duration from the point a customer request is raised or entered into the backlog to the point the deliverable is completed and handed over.

Why it matters

Customers care about lead time because it represents how long they have to wait for their order. By measuring and reducing lead time, business owners can improve customer satisfaction, streamline operations, and gain a competitive edge.

Formula

Lead Time = Completion Date - Request Date

Improvement tips

  • Track lead time starting from the exact date a customer submits a request.
  • Map your workflow to identify delays that happen before active work even starts.
  • Use lead time data to set realistic delivery expectations for your customers.

Common mistakes

  • Only measuring the time spent on active work and ignoring the queue time before work begins.
  • Using average lead times that hide major individual delays or customer complaints.
  • Failing to separate lead time metrics for different types of customer requests.

Frequently asked questions

Do I need to measure lead time before I start my business?
You cannot measure actual customer lead times yet, but estimating them helps you set realistic delivery promises for your first clients. It ensures you do not promise faster turnaround times than you can deliver.
When does lead time first become relevant for a new business?
Lead time becomes relevant the moment you receive your first customer request or order. Tracking how long it takes from request to delivery is key to building customer satisfaction from day one.
How do I estimate lead time for my new product or service?
You can estimate lead time by mapping all the steps needed to deliver your product, including processing, manufacturing, shipping, and buffer time. Researching industry averages also provides a useful benchmark.
Can reducing lead time help a startup win its first customers?
Yes, promising and delivering faster lead times than your competitors can be a powerful selling point. It shows potential customers that your new business is responsive and efficient.
Why does lead time matter for a business already running?
Lead time measures your customer's waiting experience, which directly impacts their satisfaction and loyalty. High lead times indicate operational delays that could cause you to lose customers to faster competitors.
What goes wrong when a business ignores lead time metrics?
Ignoring lead time leads to slow delivery, customer complaints, and lost sales. You may not realize your processes are blocked until customers start canceling their orders due to long wait times.
How do I start measuring and reducing lead time in my business?
Start by recording the date when a request is made and the date when it is fully delivered. Look for delays that happen before active work begins, such as order processing delays, to find quick ways to reduce wait time.
How is lead time different from the time it takes to build a product?
Lead time measures the entire customer experience, including any queue or wait time before the team starts working. The building time only measures the active production phase.
What does lead time mean in plain business words?
Lead time is the total amount of time a customer has to wait for their order. It measures the duration from when they make a request to when they actually receive the completed product or service.
Is measuring lead time complicated or risky?
Measuring lead time is very simple and has no risks. It only requires tracking two dates: the day the order came in and the day it was delivered.
Do I need special software to track my lead times?
No, you do not need special software. You can easily track lead times using a simple spreadsheet or a calendar to record order and delivery dates.
What causes long lead times and how do I fix them?
Long lead times are often caused by orders sitting in a queue, slow approvals, or material delays. You can fix them by simplifying your order process and keeping a small inventory of common materials.
