Workflow plays a major role in nowadays business and therefore its requirement elicitation must be accurate and clear for achieving the closest so- lution to business's needs. Due to Web applications popularity, the Web is be- coming the standard platform for implementing business workflows. In this context, Web applications and their workflows must be adapted to market de- mands in such a way that time to minimize effort. As they get more popular, they must give support to different functional requirements but also they con- tain tangled and scattered behaviour. In this work we present a model-driven approach for modelling workflows using a Domain Specific Language for Web application requirement called WebSpec. We present an extension to WebSpec based on Pattern Specifications for modelling crosscutting workflow require- ments identifying tangled and scattered behaviour and reducing inconsistencies early in the cycle.
