 "Design Science Research" is used based on the definitions of K. Peffers et al. The thesis is divided into six activities: "Problem Identification and Motivation", "Objectives of a Solution", "Design and Development", "Demonstration", "Evaluation", and "Communication" \cite{peffersDesignScienceResearch2007}. 
 These steps are grouped into three self-contained work packages \cite[p.~6]{offermannOutlineDesignScience2009}.
