Achieving high quality of use-case-based requirements

Zusammenfassung Seit der Einführung von Use Cases hat deren Bedeutung zur Spezifikation von Anforderungen stetig zugenommen. Die Qualit?t der Use Cases ist ein entscheidender Faktor für den Erfolg des Entwicklungsprozesses, da die meisten Entwicklungsschritte auf den Use Cases aufbauen. Trotz der extremen Wichtigkeit der Qualit?t der Use Cases stellen die meisten use-case-basierten Entwicklungsans?tze keine oder nur unzureichende integrierte qualit?tssichernde Ma?nahmen bereit (z.B. ad-hoc Empfehlungen, Erstellungsrichtlinien, einige Checklisten zur Inspektion von Use Cases). Diese Techniken werden in den meisten F?llen unabh?ngig voneinander eingesetzt, so dass bestimmte Fehlerklassen in den Use Cases durch mehrere Techniken, andere Fehlerklassen überhaupt nicht adressiert werden. In diesem Artikel wird ein integrierter Ansatz vorgestellt, in dem Use Case Erstellungsrichtlinien, Inspektionen und Simulation in systematischer Weise miteinander verknüpft werden. Der Ansatz basiert auf einer Fehlerklassifikation für Use Cases, die als Grundlage dient, die verschiedenen Techniken auf bestimmte Fehlerarten zu fokussieren .

Since their introduction, use cases (UCs) have become increasingly important for the specification of software requirements. High quality UCs are a prerequisite for project success. Despite the high importance of their quality, UC driven approaches often lack systematic and integrated quality assurance techniques. Only ad-hoc recommendations, creation guidelines, and a few checklists for inspection are available in the literature. If at all, these techniques are developed and used separately, so that one class of defects is addressed by several techniques and other classes are not addressed at all. In this paper, we present an integrated approach that combines UC creation guidelines, UC inspections, and simulation in a systematic way. We base our combined approach on a defect classification for use cases. This classification enables the requirements engineer to focus the different techniques on different types of defects.

Fan identification and national identity

It is commonly assumed that sport plays an important role for national identity. However, empirical research has primarily focused on sport’s role for emotional-affectice rather than cognitive aspects of national identity. Therefore, research presented here explores whether identification with the German national soccer team serves to reinforce ethnic or civic conceptions of national identity. Analyses of a unique dataset conducted during the 2014 FIFA World Cup and the 2016?EURO show that national team identification is an important determinant of national pride and national belonging. Respondents who identify with the national soccer team can adhere to different conceptions of national identity. It seems that national pride and affection as well as conceptions of national identity represent stable attitudes not affected by the success of the national team. Further research should improve conceptual clarity and measurement.     

Informal Learning and the Role of Social Movements

It is now widely recognised that skills and competences needed for working and living can be acquired in a variety of ways outside the framework of formal educational systems. The author calls for an enlarged view of learning that emphasises the abilities of the individual learner and includes informal acquisition of skills on-the-job. In this kind of learning the teacher has to acquire a different role, becoming more of a partner in a joint educational process. The author argues that in this regard we can learn much from the example of popular educational movements in Latin America, some of which have established successful collaboration with the world of employment. In these examples he sees indications of promising approaches for the future.
