Software variability management

During recent years, the amount of variability that has to be supported by a software artefact is growing considerably and its management is evolving into a major challenge during development, usage, and evolution of software artefacts. Successful management of variability in software leads to better customizable software products that are in turn likely to result in higher market success. The aim of this paper is to present software variability management both from a ´problems´ and from a ´solutions´ perspective by discussing experiences from industrial practice and from applied research in academia. Issues that are addressed include, but are not limited to, technological, process, and organizational aspects as well as notation, assessment, design, and evolution aspects.
