Abstract Context: Variant-Rich Systems (VRSs), such as Software Product Lines or variants
created through clone & own, aim at reusing existing assets. The long lifespan of families of …

Process models for software product-line engineering focus on proactive adoption scenarios-
--that is, building product-line platforms from scratch. They comprise the two phases domain …

Customization is a general trend in software engineering, demanding systems that support
variable stakeholder requirements. Two opposing strategies are commonly used to create …

Software engineering faces the challenge of developing and maintaining systems that are
highly variable in space (concurrent variations of the system at a single point in time) and …

When configuring a software product line, finding a good trade-off between multiple
orthogonal quality concerns is a challenging multi-objective optimisation problem. State-of …

Software companies commonly develop and maintain variants of systems, with different
feature combinations for different customers. Thus, they must cope with variability in space …

Many software systems need to exist in multiple variants. Organizations typically develop
variants using clone&own---copying and adapting systems towards new requirements …

Effectively managing versions and variants of software systems are among the main
challenges of software engineering. Over the last decades, two large research fields …

Software often needs to exist in different variants, which account for varying customer
requirements, environments, or non-functional aspects, such as energy consumption …

Software errors are a major nuisance in software development and can lead not only to
reputation damages, but also to considerable financial losses for companies. Therefore …
