This paper presents the results of a study developed in organizations located in the metropolitan region of Belo Horizonte, in Minas Gerais state. The research aimed to evaluate: (a) the information systems (IS) used by the organizations; (b) the information provided by the IS; and (c) the satisfaction of the IS’s users. The study was based on a questionnaire applied to 335 users of several IS’s at 161 different companies. The following techniques were used to analyze the data: (i) descriptive statistics; (ii) exploratory factor analysis; (iii) Kolmogorov- -Smirnov test; (iv) analysis of variance (ANOVA); and (v) the Tukey test. It was found that the users evaluated every analyzed attribute of the IS’s, and the information provided by them, as “good”. Moreover, the users most satisfied with the IS usually responded positively to the attributes evaluated.
