The Internet’s widespread popularity and the ubiquity of the World Wide Web have revolutionized the face of business, especially in the telecommunication industry. Many enterprises have moved their place of business from the physical store to the virtual store on the Internet. Therefore, electronic commerce (e-commerce) has sprung up in this era and has provided enterprises of all sizes with unprecedented opportunities for economic growth. Initially, electronic commerce focused only on business-to-customer web interaction and on business-to-business web interaction. With the emergence of business process management and of service-oriented architecture, the focus has shifted to the development of electronic services (e-services) that integrate business processes and that diversify functionalities available to customers. The potential of electronic commerce and its information technology also has attracted some telecommunication corporations—for example, Chunghwa Telecom, Singtel Telecom, and AT&T. They have built their electronic commerce environment on the Internet, too. Most of these worldwide telecom corporations have many kinds of operations support systems (OSSs) in the backend environment. Hence, TeleManagement Forum (TMF) has started to consider the next generation of OSS which is called the New Generation Operations Systems and Software (NGOSS). There are also many vendors or research centers that consider how to provide the NGOSS-centric service to the users and to integrate the business process based on service-oriented architecture. Initially, enterprises had to manually integrate services so that they could work together. However, this integration required considerable time and cost, and it worked only for the specific services that were manually linked. Adding additional services required even more effort. And then, enterprise application integration (EAI) solved these kinds of problems by working via point-to-point interfaces. As enterprises use more applications to provide additional services, the amount of integration that various tasks require to have mushroomed and the system has become hard to maintain. In order to increase the performance of EAI, some enterprises have developed the concept of business process management and service-oriented architecture. The chief objective is to implement relevant process-centric services. Business process management and service-oriented architecture enable flexible connectivity and communication among applications by representing each as e-services that let applications communicate readily with one another. In order to effectively strengthen business process management’s and service-oriented architecture’s benefits, we use an enterprise service bus (ESB) that, by functioning as middleware glue, holds process-centric services together and allows for communication between enterprise applications. In this thesis, we present a research framework, a collaboration model, and a collaboration layers to describe the method. Then, we use several illustrations to explain the generality of our method, and we focus on how international telecom corporations have become to concern with the agility, the leanness, and the integration underlying e-services integration based on NGOSS. |
