On business services representation - the 3 x 3 x 3 Approach

The increasing popularity and influence of service-oriented computing give rise to the need of representational and methodological supports for the development and management of business services. From an IT perspective, there is a proliferation of methods and languages for representing Web services. Unfortunately, there has not been much work in modeling high-level services from a business perspective. Modeling business services should arguably capture their inherent features, along with many other representational artifacts. We propose a novel approach for business services representation featuring a three-dimensional representational space of which dimensions stand for the service consumer, service provider and service context. We also discuss how the proposed representation approach provides methodological supports to the area of service orientation. Finally, we present in-progress work on the application of our approach.
