Abstract

In this research we investigate how IT infrastructure capabilities are related to IT project success from a development team perspective. We first conduct an extensive literature review and summarize the insights to suggest an IT infrastructure base model. Drawing upon several other bodies of literature, particularly the psychology literature, we then build upon the base model to propose an integrative research model for IT project success that considers both actual and perceived effects of IT infrastructure capabilities. This research model argues that (1) teamwork quality mediates the effect of technical and human IT infrastructure capabilities on IT project success, and (2) team perceptions of both IT infrastructure and team capabilities shape team perceived likelihood of project success, which subsequently affects team commitment that is crucial to IT project success. We also propose a direct-effect model that directly links all constructs to IT project success so that we can test the efficacy of our proposed research model by comparing all three models. We then collect empirical data (n = 91) through an online survey of CIO/CTOs and team leaders. All three models are evaluated and compared using the partial least squares method. The results show strong support for the proposed research model except for two IT infrastructure components. We discuss the practical and theoretical implications of the findings, and suggest several ways this research can be extended.
