Software product lines (SPL) have a long tradition and will gain momentum in the future. Today's research tries to move software development to a new quality of industrial production. Several solutions concerning different phases of the software development process have been proposed in order to cope with different problems of program family development. A major problem of program family engineering is still the missing tool support. The vision is an IDE that brings all phases of the development process together consistently and in a user-friendly manner. FeatureIDE currently provides tool support for AHEAD (a prominent design methodology and architectural model for feature-based program families), FeatureC++, and FeatureHouse.
