Design requirement identification is often the initial step in the product development process, for market-pull cases. Understanding the nature of design requirements and the sources, from where they can or should be captured, is critical to minimise this risk of generating poorly defined requirements. However, a clear view of the sources for eliciting design requirements is still lacking in academic studies, especially in the engineering design field. Hence, the aim of this paper is to better understand design requirement type and design requirement source, and to explore the interconnections between them through empirical studies. The research consisted of primary case studies in three Danish manufacturing companies and secondary data from a survey with 93 valid answers from the industry. The research findings enriched the understanding of where and how design requirements can be identified. This knowledge can be used to support companies to focus their efforts on the right sources according to the specific context. The development of a design requirement source-type model together with supportive toolboxes is suggested as the next step for further research.
