Software product line development (SPLD) can reduce the overall software production costs, but imposes extra complexity on the development process. Dealing with the commonalities and variabilities of the product variants and with the flexible software archiecture makes SPLD a real challenge. The demonstration shows how flexible product line (PL) architectures can be build by using the modeling capabilities provided by pure::variants, a commercial tool for SPLD.
Danilo Beuche (2008) studied this question.
