In this chapter, we have reviewed the authority levels in the organization and controls used for IT governance. A short definition of IT governance is to effectively lead and monitor performance of the information technology investment. IT governance exists at three levels: strategic, tactical, and operational management. Top executives are responsible for providing the strategic guidance with policies and decisions to define objectives; department directors provide tactical management with standards and plans for their subordinates. The operational functions and procedures are controlled by the managers with execution by staff workers.
