Determinants of success in IS offshoring projects: Results from an empirical study of German companies

High labor cost in western countries allows cost savings by companies engaging in IS offshoring. However, studies worldwide indicate that a large number of companies that engaged in IS offshoring are not satisfied with the outcome. Our study examined the determinants of IS offshore project success: We developed a model and empirically tested it with data collected from 304 experts who reported on projects offshored from Germany to a wide range of near and distant countries. The model posited a direct effect of offshoring expertise and trust in offshore service provider (OSP) on success, as well as an indirect effect mediated by project suitability, knowledge transfer, and liaison quality. An analysis using partial least squares (PLSs) provided significant support for almost all these relationships. However, it showed that offshoring expertise played a minor role in explaining success and the mediating constructs. Trust in OSP had a small direct effect on success and a medium to large effect on the mediating constructs. Project suitability, knowledge transfer, and liaison quality all had small direct effects on success.
