OLIVEIRA, Roberto Célio Limão de2025-03-132012https://rigalileo.itegam.org.br/handle/123456789/645This study presents how to use fuzzy logic to reduce the subjectivity in the evaluation of IT process maturity, allowing for a more precise quantification of subjective analyses. Initially, the work addresses the theoretical foundation of fuzzy logic and the maturity model for IT processes described in the CobiT® 4.1 framework. Then, it demonstrates that the application of fuzzy logic as a tool for analyzing IT process maturity in a company allows for an analytical model that captures results through simple observations and interviews, quantifying them to provide the overall maturity level of the process more accurately than an empirical analysis. The work presents a practical example of maturity analysis of processes related to information security in an IT service provider company. The proposed model can be adopted by organizations to provide accurate information that helps direct efforts to improve processes with lower maturity levels, adding value to the organization and the services offered to customers.Lógica FuzzyModelo de MaturidadeCobiTSegurança da InformaçãoGovernança de TIpdf.Engenharia Elétrica Ciência da Computação Administração de Empresas
