Assemble-To-Order describes a production environment in which a good or service can be assembled after receipt of a customer’s order. The key components (bulk, semi-finished, intermediate, subassembly, fabricated, purchased, packing, and so on) used in the assembly or finishing process are planned and usually stocked in anticipation of a customer order. Receipt of an order initiates assembly of the customized product. This strategy is useful where a large number of end products (based on the selection of options and accessories) can be assembled from common components.
Synonyms for Assemble-To-Order include Finish-To-Order and Make-To-Order.
