Introduction: management information systems currently play a crucial role in optimizing, filtering, and transforming information, which is essential for making wise decisions in companies. Objective: to describe the importance of information systems in the organizational ecosystem of companies. Methods: a document review of articles in the Scopus database was conducted to examine the influence of management information systems on decision-making in the business sector. Results: after a meticulous selection process, a total of 20 documents were analyzed. These documents were segmented in Scopus publishers as follows: Springer (5), Taylor & Francis (5), Elsevier (5), and Wiley (5). A thematic synthesis process was employed, and the most relevant information was coded and described. Conclusions: the results show that management information systems constitute a fundamental link in making wise decisions in the business sector, since they exponentially facilitate data access and control, which are subsequently used and classified as less relevant, relevant, or highly relevant information. Additionally, these systems optimize real working time, leading to a considerable increase in efficiency and effectiveness factors in companies.
