Software product lines evolve. As a consequence, deployed products of the product line need to be updated and maintained, which is often a nightmare due to custom configurations, patches, lack of documentation. In this session, we present Evoline, an architectural approach for evolution in software product lines. Evoline supports updating a software product line by extracting and visualizing architectural information. We evaluated Evoline at Egemin, a leading provider of warehouse automation solutions, and show empirical evidence for its benefits and recommendations.
