E-Commerce Systems and Components - Objectives, Requirements, Goals - the Goals of Participants - the Role of Standards - System Users and Their Roles - Business Functions & Capabilities - System Architecture and Components Jerry Gao, Ph.D Topic: Components in E-Commerce Systems

the Goals of Participants Internet commerce involves different participants. Each has its own needs and goals. There are five types of participants: Buyers (customers) Retail customers Business customers Sellers Financial processors- operates the part of the credit processing system that accepts transactions from merchants and forwards them to the merchant’s bank. Government Technologists Jerry Gao, Ph.D Topic: Components in E-Commerce Systems

the Goals of Participants Customers: Needs of retail customers: Convenience Price Selection Privacy Service Security Sellers: - Reach new markets - Create and strengthen customer relationships - Cost effectiveness - Security Jerry Gao, Ph.D Needs of business customers: Personalization Ease of use Security Topic: Components in E-Commerce Systems

the Goals of Participants Conflicts interests in sellers: - MIS may be very reluctant to deploy an Internet commerce system because it is new and different - Sales department may feel threatened by the ability of the Internet to collapse distribution channels. Financial processors: - Secured transactions - Large transaction volume - Cost structure - Added services - Minimize risk Government: - National security - Legal controls - Taxes Jerry Gao, Ph.D Topic: Components in E-Commerce Systems

Roles of Standards In information technology, a standard is a set of specifications that helps enable system built by different parties to inter-operate. In Internet commerce, standards serve two primary functions: Standards are a way of transferring power from vendors to customers. Reduce the cost of proprietary systems and technologies Standards are a way of assembling a complete system from multiple vendors. The major problem with standards --> difficult to make them simple enough to be widely adopted, complex enough to be useful. Jerry Gao, Ph.D Topic: Components in E-Commerce Systems

Roles of Standards Early versus Late Standardization: Standards efforts tend to follow one of two paths: early or late standardization Late Standardization: - Various parties work together cooperatively to build the market, or competing technologies arise and the market decides on a leader. - When a proprietary system acquires such dominant market share that it becomes a standard. This standard usually is more complex due to its origins. Early Standardization: Multiple parties get together and jointly agree on specifications. - This can work out for the benefit of everyone. - This may cause a complex standard covering too much. Jerry Gao, Ph.D Topic: Components in E-Commerce Systems

Roles of Standards Standards for Internet Commerce: - Standards aid interoperability - The best is the enemy of the good There is a strong benefit to consistency and standardization that leads to ease of use. - The good is the enemy of the best. Standardization, and particularly premature standardization, restricts innovation. Jerry Gao, Ph.D Topic: Components in E-Commerce Systems

Systems Users and Their Roles E-Commerce systems have three types of users: - Buyers of goods and services - Sellers of goods and services - System operation personnel Each user group has: - its operational function sets - its distinct role sets Jerry Gao, Ph.D Topic: Components in E-Commerce Systems

E-Systems Users and Their Roles Customer Roles: A buyer play as different roles in the the process of buying goods and services. They are: customer, consumer, purchasing agent, and so on. In some cases, the same person plays all of the roles. However, in the businesses, it is useful to consider the various roles: Specifier - this person selects what is to be purchased. Approver - this person approves a purchase recommended by the specifier. Buyer- this person negotiates the terms and conditions of a purchase and arranges for payment.

E-Systems Users and Their Roles Business Roles: A seller also play as different roles in the the process of selling goods and services in an Internet commerce system.
