This document discusses the low productivity and low interest in sustainability in the Peruvian garment industry by applying a lean green production model for SMEs (small and medium-sized companies) based on 5S tools and standardization of work. A global diagnosis was carried out throughout the company to identify the challenges affecting the company's performance, such as defective products, low productivity, and a lack of focus on the impact of its activities on the environment. The innovative model proposes a simple and low-cost implementation so that SMEs can focus their efforts on becoming sustainable enterprises in the medium and long term. The results obtained through the standardization of work showed a significant increase in staff productivity, especially in the sewing area. This involved following a structure that significantly impacted operator variation time and identifying unnecessary activities within the processes. On the other hand, the 5S audit showed an improvement in organizational efficiency, work area cleanliness and an increase in compliance from 40% to 92%. In conclusion, applying this proposed innovative model significantly increases productivity and product quality. Continued monitoring of implementation is recommended to maintain stability and to analyze new strategies for growth and sustainability in the sector.
