Exploring Domain Requirements and Technology Solutions: A Goal Modeling Approach

As a requirement engineering technique i* has been used to model requirements for a single system. In this paper, we consider whether i* can be used to explore and map user needs and requirements for an entire application domain rather than for a single system. A domain-wide requirements model can be used to assess the suitability of various technology architectures and solutions for that domain. The domain of Ambient Assisted Living (AAL) is characterized by a large variety of stakeholders with different professional and socio-cultural backgrounds. The domain is highly heterogeneous and thus suitable for our purpose of demonstrating domain exploration. We discuss the challenges in mapping that domain, and our attempts to adapt i* concepts and usage for this purpose
