In Dutch higher education institutions, IT outsourcing (ITO) is becoming more common. New applications nowadays are executed from the 'cloud'. But what to do with on premise applications? Can they also be outsourced? If so, what factors does a higher education institution have to consider when making the ITO decision of their on-premise applications? This research starts with finding the factors that are already known in existing ITO literature (in different contexts). Then, these decision factors are validated in four explorative interviews before surveying the factors within a higher education context. In total, fourteen factors are deemed to be important for Dutch higher education institutions. Based upon the survey responses by Dutch IT decision makers, a hierarchy exist in these fourteen factors. Also, this research suggest a relationship between outsourcing decision factors and the sourcing models. Additionally, outsourcing objectives seem to influence this relationship. Literature Study Approach Following Hevners design science approach (Hevner, March, Park, & Ram, 2004) ensures a link between practical relevance and the existing (scientific) knowledge base. Therefore, the study starts with investigating what knowledge is already available. For this several scientific databases are consulted: Academic Search Premier (Ebsco), Emerald Insight, Journal of Enterprise Information Management, Journal of Information Technology, Research Gate, ScienceDirect and Google Scholar. The main keywords used in the literature research are: "IT-outsourcing, ITO, IT sourcing, cloud computing, cloud adoption decision, decision models, decision factors, ITO decision factors, IT-outsourcing success factors, outsourcing objectives, reasons for IT-outsourcing, higher education" and combinations of these keywords. Only peer-reviewed articles were considered to be part of the literature study. After assessing these articles, first by title and abstract, and subsequently by reading the conclusion section, 117 papers were found to be relevant to our study. These papers can be categorized in the following topics: Advantages and challenges of ITO, decision factors, cloud adoption, decision making, generic outsourcing papers, outsourcing objectives, sourcing models, success factors of sourcing and decision methods.
