Evolving deltaoriented software product line architectures arxiv. Assuming that the hypothesis holds, we argue that featureoriented software evolution relying on automatic traceability, analyses, and recommendations reduces existing challenges in understanding and managing evolution. After the evolution feature typology has been constructed, evolution model will be created to make the evolution more specific.
