This research aims to analyze how operational sustainable business strategies and modern technologies, including employee training influence performance. The methodology is a quantitative approach with a cross-sectional design. Data was collected from 207 SMEs in Aguascalientes, central region of Mexico, through a survey administered to managers or those responsible for operations (INEGI, 2024). The data will be analyzed using EQS software to assess the relationships between the variables. This research aims to provide valuable insights into the factors contributing to firms’ operational performance success. The research model will be assessed by the reliability and validity of the measurement instruments using Cronbach’s Alpha, Dijkstra-Henseler’s rho, Composite Reliability Index, and Average Variance Extracted (AVE). So, the analysis will ensure that the constructs are distinct and not overlapping. The good fit for the proposed theoretical model will be evaluated to suggest that the relationships between the variables were adequately represented (Henseler et al., 2015). The study focuses on the crucial role of sustainable business strategies in enhancing the operational performance of SME (Buttle & Maklan, 2019; Marr, 2016; Marston et al., 2011; Sutherland, 2019). The results obtained in this study indicate that, on the one hand, the factor loading of the variables is within the norm and, on the other hand, sustainable business strategies do have a significant impact on the performance of operational activities in this type of company. This means that for manufacturing SMEs, it is very important to have a sustainable environment that allows all of their operations to be focused on the performance of their internal operating systems. The data collection period was between March and May 2024, considering a stratified random sample of companies within the state of Aguascalientes.
