Integrating e-business transactions across extended enterprises

International e-business, with the exception of international finance, is still in its infancy. Connectivity is quite common via such mechanisms as the internet and private networks, but application-to-application integration at the business process level is not well developed. This paper draws on our current implementation projects and presents a realistic assessment of e-business integration for the present. We extend the assessment by providing a pragmatic forecast for how the e-business integration model will evolve over the next few years.
