ABSTRACT
This chapter is both a celebration of existing research and a call to inspire even more influential work on sourcing of information technology services. We review scholarly research and propose future research directions. The review is based on our coding of 1,170 empirical relationships found in 257 journal articles published between 1992 and 2014. We found that scholars have primarily studied two types of dependent variables associated with sourcing: IT sourcing decisions and IT sourcing outcomes. Based on the strongest evidence from our codes, we developed a model of the determinants of information technology outsourcing (ITO) decisions and a model of the determinants of ITO outcomes. The model of ITO decisions includes 21 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 31 independent variables associated with transaction attributes, relational and contractual governance, client and provider capabilities, client characteristics, and decision characteristics. Together, these models succinctly capture a vast amount of empirical work to primarily aid client and provider organizations. Beyond helping these constituents, we examine what sourcing studies might be truly impactful. As scholars, we can help to answer societal questions about the role of IT sourcing in alleviating poverty, sustaining the environment, mitigating cyber threats, and helping workers adjust to the coming wave of automation.
