Mass-production systems can be adapted to make several different varieties of a product. Items from automobiles to toothpaste are manufactured in that way. In addition to deciding whether and when to buy, a customer selects one of the variants. The production facility must be somewhat flexible — enough to switch between variants with few delays and at a low cost, thereby retaining economies of scale.

The production process must be very flexible in order to meet those requirements. There is no finished-goods inventory —there can’t be if the product is really customized.
