What is Lead time?
Lead time means the amount of time between starting an order or step and receiving the finished result. Learn how it affects product development, prototyping, manufacturing, cost, and launch decisions.
Direct answer
Lead time means the amount of time between starting an order or step and receiving the finished result. In product creation, this term matters because it affects how a founder explains the product, compares suppliers, controls cost, or reduces production risk.
Manufacturing language can make simple decisions feel harder than they are. A useful definition should connect the term to a real decision, not just explain the acronym.
Lead time usually appears when a product is moving from idea to prototype, supplier quote, sample review, production, quality control, or shipping.
