• Assembly to order (ATO) is a business strategy in which products are quickly produced from components after order confirmation.

  • Assemble-to-order is a combination of make-to-order and make-to-stock.
  • In a typical ATO approach, the costs of assembling a product from its components are negligible, but the costs of manufacturing the various components can be significant.
  • A PC manufacturer that receives orders and then assembles custom computers using components such as keyboards, monitors, and motherboards uses an assemble-to-order strategy.
