Electronic commerce has its roots in three different IT initiatives: Inter Organizational Systems (order entry and purchasing systems), transaction automation (credit card transactions), and electronic funds transfer (financial transactions).
Read the textbook materials in chapter 4 for an excellent description of IOS concepts and two detailed case studies: American Hospital Supplies and American Airlines. These early initiatives have led to the deployment of EDI - Electronic Data Interchange. As we discussed previously this is the reason behind the success stories of today, like in the case of Wal-Mart. EDI is based on trading partner agreements and the use of standards. To see a detailed description of some of EDI standards and its role in Electronic Commerce visit this site.

We will use the same simple framework to analyze the HEB (H.E.Butt Grocery Company) case: (a) what is the problem, (b) what are the alternatives, and (c) what are the recommendations; like we have done before. We will discuss HEB first on the Web and then in class.
1. What is the problem?
Who owns the problem? Why is it a problem? Is there a decision involved? If it is a problem, what are the pros and cons that makes it a problem?
2. What are the alternatives?
What can be done? There is always the do nothing alternative. If everything went well (rosy scenario) what we would like to do? If everything went wrong (doomsday scenario) what should we do? What can we do in between the rosy and the doomsday scenarios? What are pros and cons of each alternative?
3. What is you recommendation?
What criteria should we use to select the most suitable alternative in the case? Why you are recommending one alternative versus the others? How this alternative satisfies your criteria? How to implement the alternative you selected?
