The subject of this dissertation are public policies involved in the construction of urban education facilities, more specifically, policies dealing with a management programme lauched by Pará State Government, Brazil. The work approaches programmes designed for an improvement in the management of construction woks, specifically the actions taken at the Production Costs Division of the Regional Integration Special Secretariat. This approach is justified by the need of solutions for management problems in public organizations, where decision making, in most cases is based on not precise data, leading to the course of policitical influences in detriment of decisions based on technical terms. The literature review was built upon a discussion on quality improving policies, in order to upgrade decision making processes, as well as the emergence of information systems, and specifically the management of production costs. The methodology was based on a case study about the organizational context of the Public Works Executive Secretariat (SEOP), and a survey on the construction of some educational equipments. The research inquires the processes of decistion making in order to analyse the use of reliable and shared information, for an abrighed social political and economic use in the production of education facilities. It was found that there are good management practices, although, there is a rejection by some of the technicians of the secretariat to assimilate the programmes, what brings a deficiency of flows of information and of production costs control.

The concept of User Experience (UX) has been used to achieve improvements in digital informa- tion systems based on how people perceive them. Considering the digital inclusion movement and the consequent growth in the need to provide a satisfactory user experience, research on UX assessment methods becomes essential to keep up with technological changes and promote the necessary adjustments. Despite the advancement of scientific production in the field of UX, there are still relevant gaps that highlight the need to develop new methodologies and tools that aim to provide more accurate UX assessment, given the growing demand for user-friendly applications and learning, resulting from ongoing technological and social transformations. In this context, the present work aims to develop and evaluate a user experience analysis tool capable of providing qualitative and quantitative artifacts, based on the association of interaction tracking data and UX heuristics. The methodology developed for this exploratory research has as main pillars the quantitative and qualitative methods, based on data obtained from interviews, questionnaires, in addition to the analysis of generated documents and artifacts, eye tracking, mouse, keylogging and machine learning. For the execution of the study, the T2-UXT tool (Tracking Techniques User eXperience Tool) was developed, created to perform interaction data collection by multiple data entries, the tool was evaluated in two case study scenarios. distinct areas of knowledge. For the representation of interaction data, two graphic visualization options were developed, in addition to a metrics analysis table and integration with external algorithms, which allowed for more detailed analysis using Artificial Intelligence. From this it was verified that the T2-UXT is able to assist in the evaluation of UX through artifacts that can be used as a reference for modifications and customizations in graphical interfaces.
