The growth of the InterNet has caused larged increase in the amount of information on sites that run in a more and more dynamic way. Therefore, many companies have been using content management and publication systems (CMS) to manage it. However, the re-utilization of these systems in a context other, than the original one, may result in usability problems, compromising its efficiency and user´s satisfaction, the problem of this research. In order to identify the problems and provide recommendations that may facilitate the interaction between the content management and publication systems and its users, this research has as main objective to carry out an ergonomic evaluation of the Gutenberg system of management and publication of content, through interviews and usability tests carried out with users from Faperj - Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro - and professionals from Winco - company responsible for the system´s development. In order to carry out the analysis of the results gathered through research techniques, the ergonomic criteria of Nielsen, Bastien and Scapin have been used, confirming the hypothesis that the adjustments necessary for the application of the content management and publication systems in another context may cause usability problems, making it hard for the users that utilize the system to implement and maintain the site. The recommendations brought about by this research, result of the users´ suggestions together with the researcher´s over the process of evaluation of the system, are directed to the context analyzed. However, it may also be of use as a reference to for other systems of the same segment.
