Integrated Variability Modeling of Features and Architecture in Software Product Line Engineering

Existing methods and tools supporting product line variability management typically emphasize either the feature or the architecture level. There have been attempts to combine these aspects, but no widely accepted method is available so far. This paper reports ongoing research in designing and implementing product line variability models, where the focus lies in treating features and architectural elements as parts of an integrated model. The research is carried together with our industry partner Siemens VAI
