SUMMARY:

The studies on satellites have progressed over the years, following technological advancements. As a result, the concept of small satellites, known as CubeSats, emerged, initially intended for academic purposes. However, these satellites gained prominence by assuming functions previously performed only by larger satellites. Despite this, CubeSats face significant challenges, such as low reliability in their missions, due to financial constraints, time limitations, and lack of experience among their developers, especially in academic projects. Faced with these challenges, there is a need for methods and tools that facilitate development and improve the reliability of these missions, considering their difficulties. The objective of this work is to present an adaptation of traditional failure analysis tools, FMEA and FTA, as a more agile alternative for project failure analysis, with a case study in the development of a CubeSat, aiming to simplify implementation and make the techniques more practical for teams with limited resources. The FCA has proven to be fully functional, as demonstrated in the case study, being as effective as traditional tools and providing a reduction of approximately 50% in the development stages and processes, thanks to its more objective and direct approach. In addition to the benefits obtained, the FCA has proven to be a tool of generic use, applicable to any project requiring an easy-to-use tool, with reduced application time and producing solid results, especially in teams with limited resources, thus promoting their success.
