Naming the Pain in Requirements Engineering: Design of a Global Family of Surveys and First Results from Germany

Context: For many years, we have observed industry struggling in defining a high quality requirements engineering (RE) and researchers trying to understand industrial expectations and problems. Although we are investigating the discipline with a plethora of empirical studies, those studies either concentrate on validating specific methods or on single companies or countries. Therefore, they allow only for limited empirical generalisations. Objective: To lay an empirical and generalisable foundation about the state of the practice in RE, we aim at a series of open and reproducible surveys that allow us to steer future research in a problem-driven manner. Method: We designed a globally distributed family of surveys in joint collaborations with different researchers from different countries. The instrument is based on an initial theory inferred from available studies. As a long-term goal, the survey will be regularly replicated to manifest a clear understanding on the status quo and practical needs in RE. In this paper, we present the design of the family of surveys and first results of its start in Germany. Results: Our first results contain responses from 30 German companies. The results are not yet generalisable, but already indicate several trends and problems. For instance, a commonly stated problem respondents see in their company standards are artefacts being underrepresented, and important problems they experience in their projects are incomplete and inconsistent requirements. Conclusion: The results suggest that the survey design and instrument are well-suited to be replicated and, thereby, to create a generalisable empirical basis of RE in practice.

Teaching Software Process Modeling

Most university curricula consider software processes to be on the fringes of software engineering (SE). Students are told there exists a plethora of software processes ranging from RUP over V-shaped processes to agile methods. Furthermore, the usual students' programming tasks are of a size that either one student or a small group of students can manage the work. Comprehensive processes being essential for large companies in terms of reflecting the organization structure, coordinating teams, or interfaces to business processes such as contracting or sales, are complex and hard to teach in a lecture, and, therefore, often out of scope. We experienced tutorials on using Java or C#, or on developing applications for the iPhone to gather more attention by students, simply speaking, as these are more fun for them. So, why should students spend their time in software processes? From our experiences and the discussions with a variety of industrial partners, we learned that students often face trouble when taking their first "real" jobs, even if the company is organized in a lean or agile shape. Therefore, we propose to include software processes more explicitly into the SE curricula. We designed and implemented a course at Master's level in which students learn why software processes are necessary, and how they can be analyzed, designed, implemented, and continuously improved. In this paper, we present our course's structure, its goals, and corresponding teaching methods. We evaluate the course and further discuss our experiences so that lecturers and researchers can directly use our lessons learned in their own curricula.
