Operations Management Model for Automotive Service Workshops in Peru: Service Level Improvement through Lean Manufacturing and SLP

Latin America's automotive repair SME sector faces persistent operational challenges that hinder its efficiency and competitiveness. Prior studies have explored Lean methodol ogies and Systematic Layout Planning (SLP) in large-scale industries, leaving a gap in adapting these tools for smaller automotive workshops. The discrepancies above are sought to be solved through the formulation and verification of an integrated operations management model that combines the Lean Manufacturing approach and SLP. It applied the 5S technique, layout optimization, and process standardization to minimize movements and delays. The verification step showed substantial improvement in the service level from 84.91% to 95.00%, along with a 32.99% improvement in the diagnostic time. These results demonstrate that the model can enhance service quality and operational efficiency and contribute to the academic literature and practice by providing a model usable by SMEs. Further research should assess the sustainability of the model and the use of digital monitoring systems.
