Abstract

Workflows play a major role in nowadays business and therefore its requirement elicitation must be accurate and clear for achieving the closest solution to business's needs. Due to Web applications popularity, the Web is becoming the standard platform for implementing business workflows. In this context, Web applications and their workflows must be adapted to market demands in such a way to minimize development effort. In this work we present a model-driven approach for specifying Web workflows adaptations using a Domain Specific Language for Web application requirement called WebSpec. We present an extension to WebSpec based on Pattern Specifications for dealing with crosscutting workflow requirements by identifying tangled and scattered behaviour and reducing inconsistencies early in the requirement gathering phase. Using simple but illustrative examples we show the expressive power of the approach.
