In realizing the model, two goals were targeted namely (i) to construct a requirement engineering model that support automatic transformation of domain features into actor-specific requirements; and (ii) to design and implement an interactive web based requirement engineering tool that demonstrates the requirements generation and specification process for a product line. The result obtained is twofold: (i) a model driven architecture for rapid requirements generation and specification for a product line that reduces costs and development time; (ii) tool implementation based on a web tier application framework that supports different client and actor types. In conclusion, the study is a contribution to a recently advocated idea that requirements generation and specification for product line development could be model-driven.
