Observation: there are many projects launched daily. However, few of these projects achieve the expected results. Various reasons create gaps between the final result and the initial objectives, among others, poor definition of the problem or project and, at times, an incompetent manager. Our first goal is to evaluate the management of a company using a project management theoretical model. The strengths and weaknesses of project management are identified during this comparative analysis. The second goal is to compare these strengths and weaknesses in order to verify the short and medium-term impact on this project. The following weaknesses were identified from the comparative analysis: poor definition of the problem to be solved and the project itself, as well as the lack of audit and project closure. These weaknesses, in the case studied, led to the company’s closing after only three years in business. To ensure that the company’s other projects do not suffer the same fate, it would be important for the company to further study its project management system and implement a project management process based on a recognized model.
