The article addresses improving efficiency in a small baking company. The application of standardized work, autonomous maintenance and planned maintenance is proposed to adopt better work methods, strengthen the knowledge of the company's collaborators about the necessary care activities for the equipment and have a preventive action plan that eliminates delays. within the process. A poor distribution in the plant was identified through the route diagram and process activity diagram (DAP) that generated an economic impact of 20,000 PEN. With the Arena software, the proposed maintenance simulation was carried out, with process times and failures. It was possible to validate an increase in efficiency that went from 49.29% to 70.59% based on a 10% decrease in the time of activities carried out by the operator. Regarding economic validation, an NPV of 8,751 PEN and IRR of 57% were achieved. For environmental sustainability, the Leopold matrix was carried out , which obtained a result of 0.402, which is not very significant, that is, during the production process no raw material waste is generated.
