AbstractThis paper reports on an exploratory study of the barriers and facilitators that affect technological innovation by suppliers to the automotive industry and the adoption of such innovations by the industry. The specific focus in the study was on key decision and action points in the life of specific innovations or potential innovations (ideas for new products) which may affect their successful development and marketing. The major source of data for this study was in the form of brief cases obtained from interviews of managers and technical personnel in suppliers to the automotive industry. These cases related to specific projects engaged in or ideas proposed by the responding firms or others in their sector of the industry which were aimed at the introduction of new or improved products, components, systems, materials, designs, etc., to the automotive industry.The information and data for this study were collected by means of structured interviews with 15 managers in 13 first level supplier firms to the automotive industry. A total of 32 innovations were investigated and a corresponding number of 32 cases and additional information on barriers and facilitators were generated for these 32 innovations.In general it was found that the most important barriers and facilitators to innovating were federal laws and regulations. Overall, the two types of decisions that are made in the automotive supplier's environment which appear consistently throughout these cases are (1) the automotive customer's decision to accept, encourage development of, or adopt innovations, and (2) the government's decision to mandate changes in safety, environment or energy‐relatedregulations or legislation. The policy implications of the results of this study are discussed as they relate to an evolving model of the effects of potential federal intervention in the R&D/innovation proces
