The central purpose of this study is to analyze how the implementation of quality management tools positively impacts internal efficiency and the reduction of operational costs at the hardware company located in Trujillo, within the La Libertad department. Initially, a comprehensive diagnosis of the current situation of the company is carried out in each production area. The choice to focus on the production area is justified by the identification of critical issues, especially the high number of unattended customers, which causes substantial losses for the organization. Additionally, this research work presents an improvement proposal, accompanied by a corresponding economic and financial analysis. The company addresses some of the problems that are negatively impacting its profitability, such as lack of inventory control, insufficient staff training, lack of a maintenance plan, and absence of capacity limit signage. The proposed improvement for the production section is based on a detailed analysis, including approaches and resources to monitor the processes involved in product creation and manufacturing. The goal is to ensure consistent and timely production, minimizing the occurrence of failures and associated costs. Finally, using all the collected and analyzed information, and based on the previous diagnosis, an analysis of the results is carried out to support the conclusions presented with quantitative data. This will validate the proposed improvement in the production area and contribute to an increase in the company's profitability. This results in a monetary benefit as well as a better relationship between the company and the customer.
