In the past, electronic commerce only focused on customer-to-business web interaction and on
business-tobusiness web interaction. With the emergence of business process management and of
service-oriented architecture, the focus has shifted to the development of 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 in their backend environment. In the past, enterprises
had to integrate their telecom services manually, 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. In this paper,
we present a research framework to describe the method. Then, we use two illustrations to explain the
generality of our method, and we focus on how international telecom corporations have become
concerned with the agility, the leanness, and the integration underlying electronic services (e-services)
integration with enterprise application interface technology.
