Today, many companies are organized in global networks and outsource activities that can be performed quicker, more effectively, or at lower cost by others [1]. Their competitiveness depends heavily on support systems that can keep up with constantly evolving business relationships and cross-organizational value chains. This requires methodologies, methods, software architectures, and infrastructures to support changes defi ned at a strategic level and propagate them down to the working levels in terms of business processes and associated information and communication technology (ICT) systems. One way to achieve this is by integrating the ICT systems within an enterprise and across networked enterprises.
