Review of 23 Years of Empirical Research on Information Technology Outsourcing Decisions and Outcomes

The 2010 Journal of Information Technology article, "A Review of the IT Outsourcing Empirical Literature," analyzed 741 empirical findings on the determinants of Information Technology Outsourcing (ITO) decisions and outcomes published between 1992 and 1st quarter 2010. In this paper, we replicated the method and coded additional findings published until the end of 2014. Combining the Lacity et al. (2010) with the additional findings, we used a total of 1,170 findings to produce the most robust models on ITO decisions and outcomes to date. The model of ITO decisions includes independent variables associated with transaction attributes, outsourcing motivations, influence sources, client characteristics and capabilities, relationship characteristics, and environmental variables. The model of ITO outcomes includes independent variables associated with transaction attributes, relational and contractual governance, client and provider capabilities, client characteristics and decision characteristics. The models serve as solid foundations for researchers seeking to advance academic contributions based on strong empirical data.
