We propose a new design that supports policy negotiation, process modi?cation, and interface alternation according to user needs, hence cater the service to quickly adapt to the service consumer requirements. We refer this design as Adaptive Service Design (ASD) which enables the service provider to perform: 1. Service Di?erentiation: Pre-generate multiple service descriptions for single service which facilitate di?erent groups of potential customers interaction needs. 2. Service Adaptation: identify users functionality and interaction requirements. If all current existing service descriptions mismatch with user requirements, the business processes and service descriptions are dynamically generated to meet the requirements. The basic design philosophy of ours, and one that distinguishes us from others, is that the Adaptive Service Design supports service provider to easily vary the policy, business process and service interface to dynamically adapt di?erent user integration requirements in terms of functionality and interaction patterns.
