Model Driven Engineering (MDE) was identified as a viable software development paradigm to help improve the product derivation phase of the Software Product Line (SPL) engineering process. Existing model-driven derivation approaches fail to properly address the behavioural derivation part, yielding a frustrating situation. In this paper we first introduce a(More)
