1 • p.5 IT governance is the responsibility of executives and the board of directors, and consists of the leadership, organisational structures and processes that ensure that the enterprise’s IT sustains and extends the organisation’s strategies and objectives.
• p.1 As firms strive to generate value from information technology (IT), managers are increasingly aware that IT-related decisions and behaviors must be aligned with organizational performance goals. But many individuals throughout organizations make daily decisions influencing the value received from IT. IT governance is the process by which firms align IT actions with their performance goals and assign accountability for those actions and their outcomes. To be effective, IT governance must be actively designed, not the result of isolated mechanisms (e.g. steering committee, office of IT architecture, service level agreements) implemented at different times to address the challenge of the moment. […] IT governance is the decision rights and accountability framework for encouraging desirable behaviors in the use of IT. IT governance reflects broader corporate governance principles while focusing on the management and use of IT to achieve corporate performance goals. Because IT outcomes are often hard to measure, firms must assign responsibility for desired outcomes and assess how well they achieve them. IT governance shouldn’t be considered in isolation because IT is linked to other key enterprise assets (i.e. financial, human, intellectual property, physical and relationships). Thus, IT governance might share mechanisms (such as executive committees and budget processes) with other asset governance processes, thereby coordinating enterprisewide decision making processes.
