Impact analysis of goal-oriented requirements in web engineering

Abstract

Due to the continuous changes and heterogeneous audience of the Web, a requirement engineering stage is crucial for Web development. Importantly, this stage should consider that Web applications are more likely to rapidly evolve during the development process, thus leading to inconsistencies among requirements. Therefore, Web developers need to know dependencies among requirements to ensure that Web applications finally satisfy the audience. The understanding of requirement dependencies also helps in better managing and maintaining Web applications. In this work, an algorithm has been defined in order to deal with dependencies among functional and non-functional requirements to understand which is the impact of making changes when developing a Web application. © 2011 Springer-Verlag.
