Goals and Scenarios to Software Product Lines: the GS2SPL Approach.

Goal-oriented requirements engineering (GORE) approaches for Software Product Lines (SPLs) offer a natural way to capture not only stakeholders’ goals but also similarities and the variability of an SPL. Goals to Software Product Lines (G2SPL) is an approach that guides the systematic creation of an SPL feature model from i* models with cardinality. However, by using G2SPL it is not possible to specify the behavioral characteristics of an SPL. In order to capture the system’s behavior, it is common to use a scenario specification technique. In this paper, we present GS2SPL (Goals and Scenarios to Software Product Lines), an approach for the Requirements Engineering phase of SPL development that combines G2SPL and PLUSS use case scenarios. Our approach also includes a sub-process for configuring specific applications of an SPL based on the priority given to non-functional
