Information technology has played a key role in a proper inventory management. Usability, well applied, increases the productivity of users, however, its absence increases the occurrence of errors and dissatisfaction. In order to minimize problems with the tool used in this study case and to fit an appropriate inventory management model, an analysis was performed on the tool used in inventory management, using concepts of usability, data and documentation provided. The problems found ranged from the visual inconsistency in the navigation menus without any standard, too much information polluting and confusing the user, inadequate treatment of errors and lack of feedback. The study focused on the problems found with special focus on treatment and prevention of errors and appropriate return of information to users, in order to propose a web system able to reduce errors and correction procedures, reduction of operating time interface, reducing training costs, maintenance and user support, and consequently, increased efficiency and data reliability. In pursuing this goal, a study was made in order to understand the theory of inventory management and its models, the influence of information technology and how usability can facilitate the use of the system and increase the quality of user experience. As for the methodological approach, this research is classified as qualitative and as to the procedures qualifies as a bibliographical, documentary and field research. The data used in the study were provided by the company relating to the stocks of 2008, 2009 and the first half of 2010. The study shows, in technical and usability terms, that the proposal could generate significant benefits for quality of the report of outcomes, improving performance and efficiency in the use of the system. From the inventory management perspective, the study shows that with a tool capable of providing reliable and accurate data it is possible to gain greater control of inventory through the correct application of Just in Time.
