Managers tend to base their decisions on habits and conventions and on self-confidence. The course sets out to bring the scientific process to the center of the manager's decision-making process. The course aims to discuss how scientific methodology can be used to solve business problems, in other words, evidence-based management, which means using the best available evidence in the decision-making process of organizations. The proposal is to develop critical thinking to search for the most appropriate theory, content and knowledge to produce the best evidence, reducing biases and inappropriate judgments.
