This report presents data from a national study of 118 Industry/University Cooperative Research (IUCR) projects supported by the National Science Foundation. Questionnaire responses were gathered from 226 industry and university scientists working on these projects. The purpose of the study was to describe how IUCR projects develop, how they are implemented, and discover what project features contributed to successful technical and organizational outcomes. In general, the variables that seemed to contribute to all aspects of project success were those related to interpersonal interaction. The IUCR program was conceived as building on dialogue between university and industry scientists; this study uncovered abundant evidence that this design approach was realized in practice. In summary, participation in IUCR Projects seemed to have had a significant effect on the individual scientists and their respective organizations. Overall, it appears that the theoretical orientation of the university scientists reacted synergistically with the more practical concerns of industrial scientists and yielded both scholarly outcomes and the perception of commercial success.
