What is the impact of information technology (IT) governance software on IT governance processes and through that on realizing business value from IT? This question has recently gained importance, as IT budgets continue to be under pressure, as IT governance is high on the corporate agenda, and as software applications have become available that promise to enforce and streamline IT governance processes. This article examines the underlying conceptual foundations, develops a comprehensive research framework that is subsequently applied using a multiple case design, and concludes with insights from four international implementation sites. The results indicate a positive impact on IT-related business value outcomes in three areas: portfolio management optimization, project visibility and control, and IT services efficiency.
