Comparing the intensity of variability changes in software product line evolution
Christian Kröher, Lea Gerling, Klaus Schmid · 2024
Software Product Line (SPL) evolution impacts multiple kinds of artifacts simultaneously. In previous work we analyzed the frequency and amount in which developers change variability information on a fine-grained level in the Linux kernel [2]. This revealed that changes to variability information in code, build, and variability model artifacts occur surprisingly infrequently and only affect small parts of the analyzed artifacts.
