The textile and garment sector in Peru is crucial to the economy, contributing to productive diversification and generating foreign exchange through exports. However, SMEs in this sector face significant operational challenges, including inefficient machine setup, high rates of rework, frequent breakdowns, and excessive sewing times due to lack of standardized processes. Addressing these issues is essential to enhance their competitiveness and sustainability.

The proposed model integrates Lean Manufacturing and Total Productive Maintenance (TPM) tools, such as 5S, Standardized Work, SMED, and Autonomous Maintenance, aiming to optimize production processes, reduce waste, and improve operational efficiency. This approach targeted deficiencies in machine setup, operational errors, and inadequate maintenance practices prevalent in the sector.

The implementation of the model demonstrated significant improvements. Operational efficiency increased by 32.01%, defective product rates decreased by 29.81%, and setup times were reduced by 27.26%. These results were achieved through the systematic application of Lean and TPM principles, which streamlined processes, minimized downtime, and enhanced overall productivity.

The research's impact extends beyond operational improvements, contributing to the academic literature by filling a knowledge gap in the application of Lean and TPM tools in textile SMEs. Socioeconomically, the model promotes job creation, preserves cultural traditions, and enhances the competitiveness of SMEs, fostering economic growth in the region.

This study underscores the importance of adopting efficient production practices in the textile sector. It calls for further research to explore the integration of advanced technologies and methodologies to sustain and enhance these improvements. Scholars and practitioners are encouraged to build on these findings to drive innovation and growth in the industry.
