The failure of MSMEs in Mexico is one of the highest in the world and despite the fact that the main causes of these failures have been identified and categorized: problems to sell, produce and operate, control of operations, planning and management, it has not been possible to reverse them, proof of this is their high death rate.

The purpose of this article is to propose a model of operational implementation parallel to that applied by a consulting team to a group of seven radio broadcasters in Mexico (that achieved improvement of organizational performance), which integrates the administrative and operational elements that counteract the main causes of failure by improving organizational performance, comprised by financial performance and operational performance. The research used a mixed model with concurrent design through a descriptive and explanatory case study. The importance of the operational model of implementation is to facilitate their execution by members of the organizations without requiring a team of experts to achieve it
