Abstract:
This paper presents the results of an empirical study of concept generation procedures enabling flexibility in engineering systems design. Evaluation of two educational training procedures (analogies vs. explicit) and two ideation procedures (free undirected brainstorming vs. prompting) was done. The procedures aim to improve quantitative lifecycle performance, while providing users with satisfaction with the process. Controlled experiments involved ninety participants working on a design problem in emergency services. Results suggest that combining explicit training on flexibility and free undirected brainstorming was best to improve lifecycle performance, measured as average response time and net present cost of infrastructure. No statistically significant effect was measured when comparing procedures against one another based on lifecycle performance, suggesting that any procedure could be used. Analogies combined with free undirected brainstorming led to better process satisfaction for users. The results give insights on the true effects of concept generation procedures, considering quantitative performance impacts, as well as qualitative user impressions.
