Lead Time SCM is a business term used to describe the amount of time it takes for a product or service to go from the initial order or request, all the way through to being ready for delivery or completion. It applies to supply chain management, inventory control, and the production and planning process. Lead time can be affected by many factors, such as sourcing of materials, availability of labor, and production capacity, so understanding and managing lead time is an important part of running any successful business. Knowing your lead times is essential in ensuring that clients get what they need when they need it – so they keep coming back!
