Electronic Commerce Business Interfaces The case study must examine an organisation or specific system involving (1) a comparison among three or more organisations in the same industry or service sector, which perhaps has a number of different types of EC interfaces. The case study must be based on a real electronic commerce system in Australia, Hong Kong or other International location (examples are: web sites, EDI systems, intranets, extranets, organisations planning electronic commerce systems and cashless systems). (2) Literature review to establish a robust framework about criteria for assessing and comparing the systems in the selected companies. After comparison, the best system is identified and further improvement may be recommended in the case study report. (3) Data gathering should be conducted by methods such as reading of company documents, conducting interviews, surveys or other appropriate techniques. You should attempt to visit the organisation or correspond with them in some way if appropriate. In assessing these systems, you must take some important aspects into consideration, such as: ? How the system is used to support business strategy ? Cost/benefit analysis (business case) ? Issues related with implementation and maintenance of the system ? EC processes ? What kind of electronic data transfer occurs These are required areas that must be studied, however you may also find other issues
