A decision whether to sell a joint product at split-off point or to process it further and sell it in a more refined form is called a sell-or-process-further decision. Joint products are two or more products which have been manufactured from the same inputs and in a same production process (i.e. a joint process). The point at which joint products leave the joint process is called split-off point.
Some of the joint products may be in final form ready for sale, while others may be processed further. In such cases managers have to decide whether to sell the unfinished goods at split-off point or to process them further. Such decision is known as sell-or-process-further decision and it must be made so as to maximize the profits of the business.
