In the early phase of a development process, several concept variations are developed to overcome technical problems. Despite this, only one concept makes the final selection. In this study, a theoretical process model providing an early-phase, structured proceeding guideline was adapted for use in a development process in order to simplify concept selection. This adapted process model enables a more time-efficient and transparent early-phase development process. Furthermore, it presents an opportunity for the relationship between design engineers and simulation engineers to be improved. The adapted process model was validated by using a combination of simulated models and expert interviews.
