Towards a Requirements-Aware Common Web Engineering Metamodel

In recent years, Web engineering development projects have grown increasingly complex and critical for the smooth running of the organizations. However, recent studies reveal that, due to an incorrect requirements management, a high percentage of these projects miss the quality parameters required by stakeholders. Despite this, current Web Engineering methodologies continue focusing on web design features, thus limiting the Requirements Engineering tasks to the elicitation of high-level functional requirements. This fact has caused a requirements-support gap in the recently proposed Common Web Engineering Metamodel. This paper tries to cover this gap and proposes a requirements extension for this Common Web Engineering metamodel that supports measurable requirements. The reinforcement of the role that requirements play in current Web engineering methodologies, and their explicit connection with quantitative measures that contribute to their fulfilment, is a necessary step in order to reduce some of the quality failures detected in Web engineering development projects, thus increasing the satisfaction of their users.
