Software Architectures and Multiple Variability

International audienceDuring the construction of software product lines, variability management is a crucial activity. A large number of software variants must be produced, in most cases, by using extensible architectures. In this chapter, we present the various applications of a set of modular management variability tools (FAMILIAR) for different forms of architecture (component-, service- and plug-in-based), and at different stages of the software life cycle. We discuss the lessons learnt from these studies and present guidelines for resolving recurring problems linked to multiple variability and to software architecture
