Abstract IT governance arrangements refers to the patterns of authority for key IT activities in business firms, including IT infrastructure, IT use, and project management. During the last 20 years, three primary modes of IT governance have become prevalent: centralized, decentralized, and the federal mode. These modes vary in the extent to which corporate IS, divisional IS, and line management are vested with authority for the key IT activities. While a significant volume of research has examined the influence of contingency factors on the choice of a specific mode of IT governance, most of this research has examined the singular effects of the contingency factors.
