Answer:
Assemble to order
Explanation:
The reason is that the customer places the order and all Dell does is just assemble the product and deliver it to its customers. Dell is using just in time mechanism and has all of its chips manufacturing, LED manufacturing, etc production facilities interconnected. Even its suppliers are close to its production sites. This enables Dell to produce products that the customer is desiring. So assembling products by just after taking the customer orders is "assemble to order mechanism".
