Goals and Scenarios for Requirements Engineering of Software Product Lines

Goal-oriented requirements engineering (GORE) approaches offer a natural way to capture similarities and the variability in software product lines (SPLs) development. Besides, they can effectively capture both the stakeholders’ objectives and the system requirements. From i* models, for example, it is possible to systematically obtain feature models. To complement the requirements specification of SPLs, their behavioral characteristics can be captured by using a scenario specification technique. This paper presents a process. An extension of i* that includes cardinality is used in connection with feature models and a use case scenarios to support the requirements engineering phase in SPLs development. This process also includes activities to aid the configuration of requirements artifacts for a specific product in the SPL. The paper also presents the case study being used to illustrate the proposed process.
