Variability realization improvement of software product lines

TL;DRAbstract

As a software product line evolves both in space and in time, variability realizations tend to erode in the sense that they become overly complex to understand and maintain. To solve this challenge, various tactics are proposed to deal with both eroded variability realizations in the existing product line and variability realizations that tend to erode in the future. Moreover, a variability improvement process is presented that contains these tactics against realization erosion and can be applied in different scenarios.
