Existing literature on research and development (R&D)

This review examines 43 recent papers about factors behind success and failure of innovative projects. Nine out of the 43 papers report a larger number of possible causes for success or failure and provide some rank ordering. Analyzing these rankings we find that the nine studies have a significant degree of similarity among the ten highest-ranking success factors; however, there is little similarity among lower ranking factors. The various studies remain either inconsistent or inconclusive with respect to factors such as strength of competition, R&D intensity, the degree to which a project is "innovative" or "technologically advanced" and top management support. Agreement exists, however, about the positive impact on innovative success of factors such as firm culture, experience with innovation, the multidisciplinary character of the R&D team and explicit recognition of the collective character of the innovation process or the advantages of the matrix organization.

Purpose This paper explores participants' perceived benefits and costs that influence the quantity and the quality of voluntary participation in knowledge networks in a resources-constrained economy. Design/methodology/approach A conceptual model of perceived benefits and costs of knowledge sharing is designed on the basis of literature. The influence of perceived benefit and cost on perceived quantity and quality of knowledge sharing are assessed on the basis of a survey with 283 participants in a business context within a resourcerestrained economy. Findings The results indicate that reputation, reciprocity, and altruism are perceived to benefit quantity of participation, while reciprocity, altruism, and knowledge self-efficacy are perceived to benefit the quality of participation in knowledge networks. Effort and time have a negative impact on both quantity and quality of participation in knowledge sharing. Research limitations/implications This study provides insights into the factors that influence acceptance and use of knowledge networks, and can thus influence business policies. Originality/value This exploratory study explores both perceived benefits and costs of participation in knowledge sharing in a resource-constrained economy.
