There have been many attempts to discover the critical factors that can indicate the success or failure of R&D projects and new product introductions. Because of the large number of studies that exist, the authors undertook an extensive review of the germane literature to find whether a general agreement exists about the factors leading to success or failure in new product development and R&D projects. The review shows first that even with a conservative approach to listing significant factors, the list is very long. Second, comparing the factors across studies demonstrates that different authors have found that the magnitude of significance and the direction of influence vary. Third, given the differences in context, the meaning of similar factors may also vary. The contradictory findings lead us to propose a contingency framework for the new product and R&D project models. This framework consists of a contingency cube with three contextual dimensions. Based on this framework, we propose a set of propositions. We conclude this paper with a discussion of the implications of a contingent approach for both researchers and managers in the area of management of new products and R&D projects.
