Item Facing the truth: Benchmarking the techniques for the evolution of variant-rich systems(Association for Computing Machinery, 2019-09-09) Strüber, Daniel; Mukelabai, Mukelabai; Krüger, Jacob; Fischer, Stefan; Linsbauer, Lukas; Martinez, Jabier; Berger, Thorsten; Berger, Thorsten; Collet, Philippe; Duchien, Laurence; Fogdal, Thomas; Heymans, Patrick; Kehrer, Timo; Martinez, Jabier; Mazo, Raul; Montalvillo, Leticia; Salinesi, Camille; Ternava, Xhevahire; Thum, Thomas; Ziadi, Tewfik; SWTThe evolution of variant-rich systems is a challenging task. To support developers, the research community has proposed a range of different techniques over the last decades. However, many techniques have not been adopted in practice so far. To advance such techniques and to support their adoption, it is crucial to evaluate them against realistic baselines, ideally in the form of generally accessible benchmarks. To this end, we need to improve our empirical understanding of typical evolution scenarios for variant-rich systems and their relevance for benchmarking. In this paper, we establish eleven evolution scenarios in which benchmarks would be beneficial. Our scenarios cover typical lifecycles of variant-rich system, ranging from clone&own to adopting and evolving a configurable product-line platform. For each scenario, we formulate benchmarking requirements and assess its clarity and relevance via a survey with experts in variant-rich systems and software evolution. We also surveyed the existing benchmarking landscape, identifying synergies and gaps. We observed that most scenarios, despite being perceived as important by experts, are only partially or not at all supported by existing benchmarks-a call to arms for building community benchmarks upon our requirements. We hope that our work raises awareness for benchmarking as a means to advance techniques for evolving variant-rich systems, and that it will lead to a benchmarking initiative in our community.Item The state of adoption and the challenges of systematic variability management in industry(2020-05-01) Berger, Thorsten; Steghöfer, Jan-Philipp; Ziadi, Tewfik; Robin, Jacques; Martinez, Jabier; SWTHandling large-scale software variability is still a challenge for many organizations. After decades of research on variability management concepts, many industrial organizations have introduced techniques known from research, but still lament that pure textbook approaches are not applicable or efficient. For instance, software product line engineering—an approach to systematically develop portfolios of products—is difficult to adopt given the high upfront investments; and even when adopted, organizations are challenged by evolving their complex product lines. Consequently, the research community now mainly focuses on re-engineering and evolution techniques for product lines; yet, understanding the current state of adoption and the industrial challenges for organizations is necessary to conceive effective techniques. In this multiple-case study, we analyze the current adoption of variability management techniques in twelve medium- to large-scale industrial cases in domains such as automotive, aerospace or railway systems. We identify the current state of variability management, emphasizing the techniques and concepts they adopted. We elicit the needs and challenges expressed for these cases, triangulated with results from a literature review. We believe our results help to understand the current state of adoption and shed light on gaps to address in industrial practice.Item Welcome message(2018-08-20) Berger, Thorsten; Borba, Paulo; Calikli, Gul; Botterweck, Goetz; Männistö, Tomi; Nadi, Sarah; Kehrer, Timo; Benavides, David; Martinez, Jabier; Seidl, Christoph; Guo, Jianmei; Collet, Philippe; Rubin, Julia; Diaz, Oscar; Rabiser, Rick; Elsner, Christoph; Capilla, Rafael; Noda, Natsuko; Andersson, Jesper; Mousavi, Mohammad Reza; Wortmann, Andreas; Schulze, Sandro; Xiong, Yingfei; Bonifacio, Rodrigo; Ho-Quang, Truong; Wohlrab, Rebekka; Mukelabai, Mukelabai; Andric, Tomislava; Bosch, Jan; Hao, Dan; SWTItem Welcome message(2019-09-09) Duchien, Laurence; Thüm, Thomas; Salinesi, Camille; Ziadi, Tewfik; Heymans, Patrick; Fogdal, Thomas; Martinez, Jabier; Kehrer, Timo; Teixeira, Leopoldo; Rabiser, Rick; Cetina, Carlos; Seidl, Christoph; Mazo, Raúl; Collet, Philippe; Montalvillo, Leticia; Díaz, Oscar; Huchard, Marianne; Berger, Thorsten; Noda, Natsuko; Botterweck, Goetz; Hillah, Lom Messan; Robin, Jacques; Quinton, Clément; Assunção, Wesley K.G.; Shatnawi, Anas; Tërnava, Xhevahire; Pereira, Juliana Alves; Dodo, Thùy; SWT
