This paper utilises the resource-based view as a framework to examine the interactions between information technology (IT) governance, IT management and organisational information systems. Analysis of data collected from medium and large Australian organisations indicates that IT governance capabilities act to improve IT management capabilities which in turn improve the performance of organisational information systems, specifically future-oriented accounting information systems. We propose that these interactions represent the operation of an overarching organisational IT capability. Further analysis finds significant differences in the most effective combinations of IT governance and IT management mechanisms for organisations facing differing levels of environmental turbulence. This finding highlights the importance of utilising IT governance as a higher order organisational capability to reconfigure and align capabilities and resources in response to changing strategic requirements and environmental pressures.
