Make-to-Order

In make-to-order manufacturing, the customer communicates specifications before production begins at any level in the product structure. No subassemblies exist in this manufacturing method, only raw material and components. Production begins after the customer identifies their specifications.

Examples of this production method are building products (lumber), windows, and doors. These products are make-to-order because the customer must specify the length, width, thickness, finish, style, and other attributes of these products before production can begin.
