In this paper we want to share our findings from our industrial experience in the field of system design, more precisely in production system design. We start by the observation that many rigorous designs of production systems are not facing the implementation success they suggest. We indicate three basic reasons for this: limited stakeholder involvement, lack of out-of-the-box thinking and the dominance of financial and technical evaluation criteria. Based on these findings, we suggest a five step approach: the stakeholder analysis, the definition of key performance indicators, the scenario generation, the scenario ranking and the scenario implementation.
