Enterprise Architecture Applied Towards Sustainable IT Governance

Evidence shows that investments made in the IT (Information Technology) area have a positive effect on organizational performance, even if these benefits are difficult to measure and associated with the real intention of those investments. IT presents itself as a tool and not as a guarantee of success, as this determining factor depends on how it is used and directed towards strategic alignment. This chapter sought to evaluate how much IT governance positively interferes in the achievement of strategic goals, based on the control of investments and its correct management. The results show that the organizations which adopt IT governance have their performance highly improved in relation to other companies, especially concerning profitability. Besides, the use of enterprise architecture in IT governance shows a positive correlation with corporative governance elements, encouraging the use of more efficient management mechanisms to promote sustainable IT.
