Abstract

In the development of Web-enabled systems, the business environment and its domain not only drive the identification of system needs, but also are in turn fundamentally changed by the introduction or evolution of a system. This means that a Web-enabled system that is under development will be highly volatile and the changes to the design will be likely to impact on the business domain. In response to this issue, we have previously developed a model (known as WIED) which more clearly links system designs and the business model, and can hence facilitate the identification of impacts on the business domain that arise from changes that are made to the underlying information designs. In this paper we present a case study conducted for evaluating the effectiveness of this model in supporting the identification of these impacts.
