Boundary objects in agile practices: Continuous management of systems engineering artifacts in the automotive domain

Automotive companies increasingly include proven agile methods in their plan-driven system development. The adoption of agile methods impacts not only the way individuals collaborate, but also the management of artifacts like requirements, test cases, safety documentation, and models. While practitioners aim to reduce unnecessary documentation, there is a lack of guidance for automotive companies with respect to what artifacts are needed and how to manage them. To close this knowledge gap and create practical guidelines, we conducted a design-science study together with 53 practitioners from six automotive companies. Using interviews, surveys, and focus groups, we analyzed categories of artifacts and practical challenges to create applicable guidelines to collaboratively manage artifacts in agile automotive contexts. Our findings indicate that different practices are required to manage artifacts that are shared among different teams within the company (boundary objects) and those that are relevant within a specific team (locally relevant artifacts).
