    We have perceived barriers that prevent requirements engineers from contributing properly to the development of the software systems that underpin the digital transformation. We have also realized that breaking down each of these barriers would contribute to requirements engineering (RE) becoming ubiquitous in certain dimensions. In this paper, we point out the transformation that is required to break down each barrier and briefly discuss each dimension of ubiquity. Our goal is to raise the interest of the research community in providing approaches to address the barriers and move towards ubiquitous RE.

    Die Durchführung erfolgreicher offener Workshops bedarf einer intensiven und sorgfältigen Vorbereitung und Organisation. Umso enttäuschender ist es, wenn am Ende fast niemand kommt. Diese leidvolle Erfahrung mussten wir in der Vergangenheit im Rahmen unserer Living Lab Aktivitäten in den ""Digitalen Dörfern machen. So haben wir mit Hilfe eines Klassifikationsschemas für Living Lab Aktivitäten innovative Ideen für die Durchführung von ""undercover""-Aktivitäten erarbeitet. Eine zentrale Eigenschaft dieser Aktivitäten ist es, dass sie sich leicht in den Alltag von Nutzern integrieren lassen oder sogar so durchgeführt werden können, dass die Nutzer gar nicht bemerken, dass sie gerade an einer ""Workshopaktivität"" teilnehmen. Das Klassifikationsschema und Vorgehen lässt sich sicherlich gut in andere Projektkontexte übertragen, so dass dieser Beitrag auch als Inspiriationsquelle für andere dienen kann, die sich mit der Problematik konfrontiert sehen.

    We are now living in the era of digital transformation: Innovative and digital business models are transforming the global business world and society. However, the authors of this paper have perceived barriers that prevent requirements engineers from contributing properly to the development of the software systems that underpin the digital transformation. We also realized that breaking down each of these barriers would contribute to requirements engineering (RE) becoming ubiquitous in certain dimensions: RE everywhere, with everyone, for everything, automated, accepting openness, and cross-domain. In this paper, we analyze each dimension of ubiquity in the scope of the interaction between requirements engineers and end users. In particular, we point out the transformation that is required to break down each barrier, present the perspective of the scientific community and our own practical perspective, and discuss our vision on how to achieve this dimension of ubiquity. Our goal is to raise the interest of the research community in providing approaches to address the barriers and move towards ubiquitous RE.

    RE and Society: A Perspective on RE in Times of Smart Cities and Smart Rural Areas

    Our requirements engineering (RE) community has known for decades that the success or failure of RE methods heavily depends on the context in which they are applied. Thus, many experiences have been gained and shared in the community that reflect which RE methods are suitable for a specific context, such as embedded systems development (e.g., automotive or military domain) or information systems development (e.g., banking or flight control domain). Nowadays, in times of smart cities and their counterpart smart rural areas, where newly introduced IT systems have a strong effect on our society, a new and challenging context arises for RE, which opens up new research questions. As a contribution to this situation and to foster discussions in our community about whether our RE methods are appropriate in this new "social context", this perspective paper reflects on the state of the art and on our own experiences in applying RE in the context of smart rural areas. These results might also pertain in the context of smart cities that pose similar challenges to RE. In addition, we present a framework comprising both an initial classification of social contexts, particularly their end users, and a classification for RE methods. Example usage scenarios illustrate how this framework helps to reflect on the suitability of our RE methods, and, if necessary, provides the basis for adapting them or creating new ones. Finally, we outline a roadmap with research questions and related activities with which we want to encourage our community to perform the proposed research activities in order to enrich our body of experiences and adapt our methods to this highly relevant context.
