A Requirements Management Template in Polarion for Model-Based Development of Airborne Systems

With numerous startups and small companies entering the market of air mobility, safetycritical system development has become relevant for an increasing number of project teams with little or no experience in that field. In a previous publication, we presented a custom software development workflow for research and prototype development based on objectives from industry standards DO-178C and DO-331. An important part of this custom workflow is requirements management since poor requirements and a lack of proper traceability has been attributed as a major source of project delays and increased costs. This paper presents the setup of an extended data model in the application lifecycle management platform Polarion including the artifact types and their attributes. Exemplary key workflows are demonstrated. It also provides more details regarding the linking strategy between the textual requirements and model artifacts in the MathWorks toolchain, as well as the trace report for the requirements including links to model artifacts and source code. The setup has proven its functionality in multiple projects at our institute without significant rework.     «
