Abstract: Web services have been developed in recent years as a fundamental technique for the new generation of business-to-business (B2B) or enterprise application integration (EAI) applications. For their widespread that imposes a new vision of service-oriented computing, the software industry has shifted its attention on software from developing a product as required to delivering a service on demand. In order to gain the many benefits from such a service-oriented model of software, several critical issues need to be addressed in a service-oriented environment such as differentiation of services with multiple attributes, dynamic selection and provision of services in a supply chain style, and commitment of services with prescribed rules. From the perspective of management, these issues are concerned within a process of negotiating desired services in a service-oriented environment. For the development of such a negotiation process, I introduce in this chapter an object-oriented method that identifies and specifies the negotiation process with explicit modeling constructs addressing these critical issues. The method starts from the identification of the negotiation process and its encompassed issues, through the recognition of an environmental architecture that supports the identification and realization of these process issues, and finally ends with the analysis and design of the architectural classes/objects that collaborate to identify and realize these process issues. The method is use case driven with UML notations utilized and extended as its modeling tool. Finally, some guidance on how the method is applied in a step by step manner will also be presented.
