Average, consistently achieved lead-time from customer order origination to customer order receipt, for a particular manufacturing process strategy (Make-to-Stock, Make-to-Order, Configure/Package-to-Order, Engineerto- Order). Excess lead-time created by orders placed in advance of typical lead times (Blanket Orders, Annual Contracts, Volume Purchase Agreements, etc.), is excluded. (An element of Total Supply Chain Response Time) Calculation: Total average lead time from [Customer signature/authorization to order receipt] + [Order receipt to completion of order entry] + [Completion of order entry to start manufacture] + [Start manufacture to complete manufacture] + [Complete manufacture to customer receipt of order] + [Customer receipt of order to installation complete] Note: The elements of order fulfillment lead time are additive. Not all elements apply to all manufacturing process strategies. For example, for Make-to-Stock products, the lead-time from Start manufacture to complete manufacture equals 0.
