Analyzing iterations in mechanical design processes – a method for data acquisition in meso-level studies

Mechanical design is the process of defining a mechanical system for a specific behavior. To support mechanical engineers in their tasks, research in studies on the design process is important. Currently there is a lack of meso-level studies on iterations in mechanical design research. We propose a documentation method for such studies. Target of the method is enable identification of iterations in mechanical design processes. Iterations occur regularly in design processes and can have an impact on project cost and quality. Therefore, they can be used to identify methodical need. We apply the method in three mechanical design projects and show its suitability for mechanical design process research.
