IT governance is one of these concepts that suddenly emerged and became an important issue in the information technology area. Some organisations started with the implementation of IT governance in order to achieve the fusion between business and IT. This paper interprets some important existing theories, models and practices in the IT governance domain and derives research questions and research propositions from it. They are the basis for pilot case research in Belgian organisations. Conclusions from these pilot cases are presented in this paper together with implications for further research.
