Retailers: Retailers are in the final stages of commodity circulation. They sell computers directly to the end consumers.

6.0 How the needed supplies can be made sustainable for protecting the continuous flow of the computer?

They mainly protect the continuous flow of computer through logistics, the flow of commerce, information flow, and capital flow (Gang Shen, 2011).

Logistics is the main process of material flow, which plays an important role in the development of new computer. Procurement department purchases the raw materials of new computer from suppliers, then processes, storages and transports to vendors, finally the new computer will reach consumers from retailers.

The flow of commerce is mainly trading process. On the one hand, suppliers accept the orders of procurement department then make contracts. On the other hand, sales department accepts the orders of distributors and retailers then make contracts.

Information flow is the flow of goods and trade information. Company publicizes the new computer’s information to consumers through sales department, meanwhile, sales department will feedback consumers’ views of new computers to the production sector timely. This can help managers make better decisions for the new computer.
