Due to rising complexity of systems, the efforts needed for their development continue to increase. Particularly affected is the specification phase. As a result the widely adopted use of (natural language) text to describe system's requirements is no longer sufficient. The application of graphical models seems to be a viable solution to this problem. However graphical models cannot replace textual requirements. They amend them instead. To specify the functions of a system, an industry partner (Daimler AG) has implemented an approach that uses coexisting UML Activity Diagrams and textual descriptions. In this talk results of a number of studies on this approach are presented. Our results show that users of these contents perceive a benefit from the approach, but also face a number of new challenges while using coexisting software artefacts. Various suggestions on how to apply the approach address these challenges. The suggestions are extended by a technical solution that ensures consistency between the respective artefacts.
