Cutting‐Edge Topics on Dynamic Software Variability

The story of success of software product line engineering and software variability, as the cornerstone to support the diversity of the product portfolio is widely recognized by software companies. Nowadays, the complexity of new software‐intensive systems demanding development challenges, such as runtime reconfiguration operations, autonomous behavior, and swarm capabilities among others, makes the weakness of current software variability techniques explicit as feature models are unable to reconfigure themselves. Therefore, we address in this chapter the challenges, problems, and solutions that dynamic variability can offer, and we also highlight the role of dynamic software product lines as emerging software development paradigm.
