Demand-driven Development of Service Compositions in Organizational Networks
Abstract
Organizational collaborate more and more in organizational networks to remain competitive. New systems can be created by assembling a set of elementary services provided by various organizations. Several composition methods are available, yet these methods are not adopted in practice as they are primarily supply-driven and cannot deal the complex characteristics of organizational networks. In this paper, the authors present a service composition development method and a quasi-experiment to evaluate this method by comparing it with existing ones. The development method is able to deal with incomplete information, to take the demand as a starting point, to deal with news services that do not exist yet, to include and to evaluate non-functional requirements, to show various stakeholder views, and to help to create a shared vision. Visualization and evaluation of alternative compositions and negotiation about the desired results are important functions of any composition method in organizational networks.
