Reuse and Requirements Engineering are very important for efficient and successful product development. However, there are many open issues for performing them well in practice, especially reuse of requirements. This paper addresses several of these issues by making use of parameters and discriminants for product line requirements. Discriminants are a special kind of requirement that differentiate one product from another. They represent qualitative variability in a product line model, while parameters represent quantitative variability. In this paper these techniques are combined in the form of parameterized discriminants. Using the techniques and a metamodel for the representation of a product line model, a stakeholder-viewpoint oriented process is defined for capturing product line requirements and constructing a product line model.
