SUMMARY:

The use of the information system brings constant benefits to those who use it, due to the increase in data generated. Grouping this information can be useful for daily activities in any work environment, and even in personal life. When talking about information system, we do not necessarily talk about computerized system, but organization, either through some automated platform or simply in a manual file. Along with the use of SI, there are risks that involve its development and that may affect its perceived usefulness. Thus, the objective of this dissertation was to propose steps to minimize the risk factors that impact the use of use of information systems delivered by the Undersecretariat of Information Technology of the Ministry of Agriculture and Livestock. Initially, it was important to search the literature for the risk variables that the authors understand to be most relevant. Subsequently, the structural equations model was applied to relate these variables and thus identify the factors with the greatest impact on the use of the IS. Regarding the practical implications, a questionnaire was first applied, where 71 responses were collected. The main results are: Perceived Utility influences the use of IS in 38.24% of cases; and Ease of Use influences Perceived Utility 15.21% of the time. In addition, the importance-performance map (IPMA) was generated to enrich the results of the PLS-SEM model and assist in the prioritization of the variables of greatest relevance and impact. In order of high importance and high performance, the indicators perceived utility and risks will be prioritized. Moreover, the moderation of the model revealed the variable Age as a point of attention because it is a variable of impact on the perceived usefulness of information systems.
