For commodity products, Xerox coined the term deliver JIT: that is, the product had to be delivered out of stock. Where sales forecasts are traditionally poor, the challenge was one of flexibility, simplicity and speed of manufacture. For mid-range products, it was unrealistic to hold ‘just in case’ inventories of products that are too complex to be assembled quickly. Instead, finish JIT was the term coined to describe the new policy of building semi-finished products with the minimum of added value, consistent with being able to complete and deliver the product in the five-day target. Finally, build JIT was the term used to describe the new philosophy of building larger products quickly within a defined lead time.
