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

TL;DR

This paper presents a globally designed family of surveys to empirically assess requirements engineering practices, with initial results from Germany highlighting common challenges like incomplete requirements and underrepresented artefacts.

Contribution

It introduces a novel, reproducible survey framework for studying RE practices across countries, enabling long-term empirical insights.

Findings

German companies report incomplete and inconsistent requirements

Artefacts are often underrepresented in standards

Survey design is suitable for global replication

Abstract

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.
