COSVAM: a technique for assessing software variability in software product families

Evolution of variability is a key factor in the successful exploitation of commonalities in software product families. Assessment of variability can be used to determine how the variability provided by a product family should evolve. We present COSVAM (COVAMOF software variability assessment method), a variability assessment technique that specifically addresses evolution of variability. We exemplify our approach with the Dacolian case study.
