The generic rationale of IT governance and IT outsourcing is similar. Both aim to increase business value delivery from IT. This article examines empirically how IT governance maturity evaluations of 109 senior executives in 20 enterprises differ, between those enterprises that have outsourced their IT function selectively and those enterprises that have conducted total outsourcing of their IT function. We collected survey data with an instrument, which builds on a generic IT governance framework and measures IT governance maturity. The article also evaluates whether the survey instrument is applicable to research that compares selective versus total outsourcing in the context of IT governance. In statistical analysis, we found several differences between selective and total IT outsourcers.
