Most research on service matching and composition (or bundling) has been technical in nature, viz., at the IT service level. Very little has been done on value-based service matching and bundling. By “value-based”, we mean the value added by a service over and above the basic functional requirement that the service is supposed to satisfy. Examples of value added could be lowered cost, higher performance, improved security, etc. To that end, in this paper, we present our idea of a Service Value Broker (SVB),that performs value-driven service matching and bundling. Via an approach specifying business and technical interfaces for business services and IT services respectively, we show how value can be calculated and integrated at the business layer. Further, we also show how our approach makes it possible to determine the appropriate IT services to be selected so as to provide the required value add at the business layer. We demonstrate our ideas via a realistic case study in the E-Commerce domain.
