IT governance is one of these concepts that suddenly emerged and became an important issue in the information technology area. Many organisations started with the implementation of IT governance in order to achieve a better alignment between business and IT. This research document carries interpretations regarding important existing theories, models and practices in the IT governance domain and presents research questions derived from it. Next, multiple research strategies are triangulated in order to explore how organisations are implementing IT governance and to analyse the relationship between these implementations and business/IT alignment.
