"Information Technology for Management" is an excellent source for reviewing and understanding the various forms of business models. As defined by Turban, Volonino, & Wood (2013) "Electronic business (e-business) is business that uses the Internet and online networks as the channel to consumers, supply chain partners, employees, and so on". Much of the information in this chapter can be very useful in preparing your system proposal as some of these models may be applicable to the Riordan Corporation. You are all familiar with at least one of these forms, B2C if you have ever made an online purchase. The five models discussed are all worth investigating especially the newer model that involves online auctions. Perhaps you have stayed up all night trying to purchase a 60" TV at a bargain price. If so tell us about your experience, document your post properly with at least one reference wherever possible. What say you all?
