Few businesses have been as important to the worlds economy as the Information Technology industry. The growth of companies has boosted the economy and broken paradigms of time and space. The tasks can be made, now, faster than ever even if someone is far away. The IT industry and in particular the Northeast IT industry has showed increasing participation in the countrys economy. Many companies have emerged and innovations have been developed all the time by firms of all sizes, including micro, small and medium enterprises the focus of this work. Besides the direct impact on the economy, these highly innovative companies also provide facilities to businesses of all other sectors of the economy and help improve it. Thus, this studys objective is to investigate the performance of these firms, analyzing it from a different quantification methodology - the fuzzy logic. The fuzzy logic is particularly useful in the definition and quantification of data where the categories to which these data belong is not clear, ie where the values belong to different categories. Thus the performance of a company can be analyzed taking into account indicators usually difficult to quantify. The data serve as input to a process of fuzzyfication, where they undergo the inference of some rules and then generate discrete values to be used for the analysis of performance itself. The research was conducted with Information Technology industry experts to describe a model composed with the main indicators for companies of the industry. After this, these indicators were engaged in categories, through fuzzy logic, composing a indicator for the overall performance of the organization. In the fuzzy logic controller, the indicators were transformed into fuzzyfied variables, suffered some rules inference and then, combined, created a variable that represented the performance of an IT company. As result, a model based on fuzzy logic was presented and then, compared with expert opinion, it represented satisfactorily the performance of a IT company based on hypothetical values generated randomly. Thus, one can conclude that the method of performance analysis proposed in this work is valid and can be a useful tool for management support.
