This research aims to contribute towards a better understanding of the importance of IT governance and IT management, according to the Resource-based View, in order to overcome the modern challenges Brazilian public organizations face as part of their institutional mission of providing proper quality, secure and efficient public services to the citizens. The study was developed based on the data collected by the TCU from 482 organizations that responded to the Integrated Survey of Public Organizational Governance (iGov2017). The data was treated quantitatively using multivariate techniques such as common factor analysis and cluster analysis. Furthermore, a performance comparison of the concluding four groups was conducted, in terms of compliance with the current legislation regarding provision of high-quality public services. The survey revealed that 47,7 percent of the organizations exhibited incipient levels of IT governance and IT management with impacts on the quality of the public services provision. Indexes on risk management, IT service level management and information security management stood out negatively. On the other hand, 19 percent of the organizations showed satisfactory levels of results and maturity of IT governance and IT management. Evidence indicates that there is a positive correlation between the quality of IT governance and IT management and the targeted results of the organizations. The outcome of this research suggests that a complex, harmonious multifaceted orchestration that ensures a consistent and continuous alignment between strategic decisions, IT strategic alignment, risk management, IT governance and IT management decisively affects Brazilian public organizations performance.
